The Strange History of Kombucha: From Russian "Tea Fungus" to Global Phenomenon

What do we call this drink?

Depending on which website you read, kombucha was invented in China, discovered by a Korean doctor, given to an emperor, or has existed for thousands of years.  The real history is far less certain, but even more interesting.

We make and drink чайный гриб (pronounced chaynyy grib). I like it.  I have read many places on the internet where it is referred to as Чайный квас (chaynyy kvass), and many westerners refer to it as 'Kombucha'.  Whatever you call it, this is a great drink, and Like many traditional household ferments, it is also surprisingly cheap to make.  Like many common things, the history of kombucha is surprisingly intriguing. 

We don’t know definitively where kombucha originated, nor do we know how it got its popular western name 'Kombucha'.  

It is noteworthy that Kombucha is not the same as Japanese kelp tea, which is confusingly called 'konbu-cha' or 'kobu-cha'.  Kelp tea is a tea made from kelp, kombucha is made from fermenting tea.  

The history of kombucha is interesting.  I will split this into parts, recent and verifiable history, and older history that needs a little deciphering.  All of the history is fascinating, and while we cannot prove exactly where kombucha originated, the earliest reliable records I can find point to Russia and Siberia as the first documented home of kombucha.

The Mystery of the Name Kombucha

While we cannot know exactly where kombucha first developed, the earliest reliable records we have of the drink are from Russia in the early 1800s.  We know that kombucha entered the western nations through Russia.  We know when and how it left Russia, and we know where it went once it left Russia.  This part of kombucha history is not under any debate.  

We also know in Russia it was (as it still is today) referred to as чайный гриб, which translates to something like 'tea fungus'.  In English this would be pronounced something like chaynyy grib.  This is what everyone grew up hearing it called.  Sometimes it is just called grib, which means something like 'mushroom' or 'fungus'.  Today in places where people speak more English, when talking about kombucha I hear people say things like ‘we used to have our own mushroom’ meaning that they used to brew kombucha at home.  I am yet to hear anyone Slavic call it kombucha.  The name чайный гриб has been used for so many generations of Russians that, if it did have a previous name, it was well and truly lost that name generations before leaving Russia.  

It makes no sense that when going from Russia to Germany and further west that it would revert from the commonly used name чайный гриб to an unused previous name of 'kombucha' that no one ever used or even remembered.  Logically, it could keep the name чайный гриб, or take one or more translated versions of чайный гриб, or possibly get a new name entirely.  It seems far more realistic that the name kombucha is a completely new name that it was given after it left Russia, and it had never been called that before.

The Earliest Documented Records: Kombucha in Siberia

The available historical evidence points most strongly toward Russia and Siberia as the earliest documented home of kombucha. 

Evidence strongly suggests that kombucha was popular from the early 1800s in Siberia.  Kombucha appears to have been a familiar household ferment in many parts of Siberia, passed between families in much the same way other traditional cultures were.  It seems like many households had it, the babushkas made it with leftover tea and ladled it out for the family.  This makes sense as the samovar was an integral part of Russian life, every family drank a lot of tea.  Russians did not waste food, and left over tea was used to make kombucha.  This was a folk medicine to keep the family healthy and strong.

While there are several references to kombucha, there isn't a huge amount written from back then as most commoners were illiterate, and kombucha was so common that no one really bothered to write about it.  Still, there are some references to it, most mention it in an off hand way as if they assume that everyone knows of this common thing.  

Tea would have been expensive in those days, but many babushkas still made kombucha for their families to keep them healthy.  We know that tea was in Siberia in the 1600s but it was expensive, and that people also made tea substitute using Bergenia crassifolia (and a few other plants).  Because B crassifolia was traditionally used as a tea substitute in Siberia, it is possible that some households used similar substitutes when making fermented tea drinks, although direct historical evidence is limited.  This plant was native to Siberia, and would have been easily obtainable by everyone in that area, so it is possible that some households could have made fermented tea-like drinks even when traditional tea was prohibitively expensive.  

In 1835 a Russian government official was sent to Irkutsk, Siberia.  As documented in the 1835 travel diaries of Russian researcher and official P. R. Stantsevich during his expedition:

“Irkutsk is an amazing city. Here tea is drunk not only hot, as is customary for us, but also cold, insisting that it has a slippery cake, like a mushroom that grows on rotten stumps. However, the drink is quite tasty, similar to our Vyazma kvass.”

This description closely resembles kombucha as we know it today, although it does not explicitly name the culture.  It is highly likely that this was referring to kombucha, and if so this is one of the first written records of kombucha.  This description is important because it is not a legend written centuries later, nor was it a marketing ploy.  It is a contemporary observation from someone describing an everyday household drink.

From Siberia, kombucha spread throughout Russia, and then seems to have started spreading out of Russia and went a little further west as mentioned above.     

This is where the documented history of kombucha ends.  We know kombucha was in Siberia in the early 1800s.  Everything older than this needs a bit of consideration and guess work.  

From Russian Household Ferment to European Health Tonic

We know that kombucha spread to the world at large from western Europe, and we know that it reached western Europe from Russia.  

In the 1910's there is mention of kombucha in Poland, with various newspaper articles and classified ads mentioning a “Japanese mushroom”.  There is broad agreement that this kombucha had not come from Japan, but had come from Russia.  Back then, people would name things to sound mysterious and foreign.  Adding the name 'Japanese' helped things to sound more decadent, much like how the tomato called Japanese Black Trifele is actually an old heirloom Russian variety of tomato.  When things sound mysterious and ancient they tend to sell better.

From there kombucha began to gain popularity across Europe.  By World War I there start being reports in newspapers of kombucha being used as a 'health tonic'.  Kombucha appears to have become increasingly known in Germany and other parts of Europe after the First World War, likely helped by contact between Russia and Europe during this period.  I have read various internet claims that when soldiers and prisoners of war returned from Russia they brought the culture with them.  To put this in perspective, penicillin was not available until 1928, which was after World War I had ended.  

Interestingly, after kombucha left Russia it was thought of as a 'health tonic' or 'medicine', it was sold as a 'cure all' that almost had magical properties.  

There are scattered accounts of folk practices surrounding kombucha, including attempts to increase its perceived potency through religious symbolism.  I read several accounts of people in Italy stealing holy water to use in kombucha in an attempt to make it more potent.  I also read that this caused a stir, and all kinds of efforts were made to prevent people doing this.  

This seems to have been a local cultural practice rather than something connected to kombucha itself.  In Orthodox communities, holy water has traditionally had a different cultural role, including being used in households.  Holy water is freely given out in Eastern Orthodox churches, and people commonly use holy water to cook with or drink sips of it each morning.  No one really writes about cooking with holy water as it is such a common practice that it doesn't need to be said.  

It is possible that using holy water in kombucha was also practiced in pre-Soviet Russia, but this is difficult to prove because ordinary household practices were rarely recorded.  Much like orthodox Christians using holy water in cooking is so common nowadays that no one bothers to write about it, using holy water to brew kombucha back then would likely have been so common that no one would have bothered to write about it.  

It seems once kombucha left Russia it spread in almost every direction by multitudes of people, and there is no one historical journey from this point.  From here on it just spread, countless individuals and families took it with them to countless new places.  Most people made it for its health benefits, some liked the taste, and some wanted to make money from it.

All of this modern history places the earliest documented use of kombucha in Russia.  This is not under dispute, what does cause controversy is the question of the history of kombucha before Russia (and if kombucha even existed prior to being in Russia).

The Older History: Separating Evidence From Legend

Did Kombucha Really Come From China, Korea, or Japan?

The internet speaks of kombucha as originating in China, or Korea, or Japan, each of which are difficult to support with historical evidence.

A lot of kombucha websites particularly focus this claim on China, yet the reasoning behind this claim is lacking.  It seems the claim that kombucha may have originated in China is made purely on the basis that tea was common in China, and this claim seems to ignore all evidence indicating this may not be the case. 

Kombucha does not appear to have the same longstanding household tradition in China, Korea, or Japan that it has in Russia.  Many Chinese people have never heard of kombucha, and the ones who have mostly see it as a new thing.  

Although kombucha is often described online as originating in East Asia, clear historical evidence linking the modern drink to China, Korea, or Japan is difficult to identify.  

The Korean Doctor Kombu Story Seems Unlikely

The internet speaks of the name kombucha as being the old name for this drink, which is improbable.  It is far more likely that the name kombucha is a relatively new name that was made to sound mysterious and oriental. 

There is a story that the word 'kombucha' was made by combining the name of a Korean doctor (called Kombu) with the word for tea (chai).  Combining words like this for something new is imaginable, and without thinking about this further you could be excused for believing it is true, but in this case it does not appear to be where the name kombucha arose.  While this is romantic, it is unlikely to be true for a number of reasons.

Many websites mention a Korean doctor with the surname of Kombu from the kingdom of Silla on the Korean Peninsula.  It is said on many websites that he gave a curative tea drink to the Japanese Emperor Ingyō.  While this is commonly mentioned on kombucha websites, historical documents seem to lack any reference to a doctor by this name.  If this doctor did exist, he was not remarkable enough to be written about.

To add to this, Kombu does not appear to be a Korean surname, or if it is, it is a very rare surname.  

While an unremarkable doctor with a unique name does not mean that he did not exist, it begins to cast a little doubt on the accuracy of the story.  

The only reference I can find which makes any mention of this has the medic’s name as 'Kon Mu' (which is almost like kombu), unfortunately this may be a completely different person as this reference says nothing of him using any form of curative tea.  

Combining the name for tea with the name of a doctor not mentioned in history with a unique surname do not rule out this story by itself.  The most glaring issue with this story is why this common name would exist now.  

If the name was made by combining the name of the doctor with the name for tea (which sounds reasonable enough) why would the name have then been changed when it entered Russia, kept as the new name for several generations (to the point that the old name had long been forgotten), and then upon entering new lands with several new languages be changed back to the now forgotten old name.  This creates a historical problem that is difficult to explain.

Did Sugar Influence Where Kombucha Developed? 

The basic idea is that kombucha probably first came about because someone left some tea out and the right combination of microbes colonised it.  A lot of tea was in China, therefore people assume the chances of this happening in China were probably high.  But there is one significant problem with this.

Kombucha needs sugar in order to ferment.  

Tea was traditionally made without sugar in China and Japan.  This adds evidence that kombucha probably did not spontaneously originate in China or Japan.  

Tea in Russia was traditionally made with sugar (or with some other natural sweetener).   

Kombucha is commonly consumed in Russia, there are various family traditions surrounding this.  

Japan and China do not traditionally drink kombucha, traditionally they drink tea (without sugar), or they drink kelp tea with a name that sounds similar to 'kombucha'.  This kelp tea superficially looks similar to чайный гриб, and also comes from the Mysterious East, this means kombucha may have gained the common name while being an entirely different beverage.

So, Where Did Kombucha Come From?

While we may never know exactly where kombucha first originated, the history we can trace is fascinating enough without adding myths.  The earliest plausible and reliable records we have point to Russia and Siberia, where чайный гриб was kept as a household ferment and passed between generations before spreading across Europe and eventually the rest of the world.

Some of the popular stories about kombucha's origins are intriguing, but many are based more on assumptions, similar names, or modern retellings than on historical evidence.  The real story is less mysterious, but perhaps more interesting: a simple fermented tea culture survived through ordinary households, was shared between families, and eventually became a global drink.

Kombucha's history is not a story of one famous inventor or a single moment of discovery.  It is the story of countless people keeping a living culture alive, generation after generation.

    The Weird History of Milk Kefir: Ancient Myths, Scientific Mysteries, and the Woman Who Changed Kefir Forever

    Depending on which website you read, milk kefir grains are said to have been either a gift from the Prophet Muhammad, food eaten by Abraham, impossible for scientists to recreate, or over 4,000 years old.  Surprisingly, much of this isn't supported by historical evidence.  The true story of kefir is even more fascinating and bizarre.  

    Modern kefir has a surprisingly well-documented history dating to the North Caucasus and early twentieth-century Russia, while many of the much older stories are fascinating but poorly supported by historical evidence.  Some parts of kefir's history have been lost entirely.  Other parts can be pieced together from historical records, archaeology, and later evidence.  

    In this article, I'll look at what archaeology, historical records, scientific research, and religious traditions actually tell us about kefir.  Some of the oldest and most often told stories that sound perfectly believable are surprisingly poorly supported, some of the newest discoveries are genuinely exciting, and one chapter in kefir's history is so bizarre it sounds like it was lifted straight from a fairy tale.

    The Extraordinary Story of How Kefir Reached Modern Russia

    Evidence level: Strong

    Remember the fairy tales/fables where something bad would happen, and everyone would lament if only someone could tell the Tsar then he would make everything alright?  Well, this is pretty much what happened with milk kefir.  

    The first reliable references to kefir grains that can be traced to today come from Russia, and are surrounded by a true story that sounds like a fairy tale.  

    Until the early 1900s, kefir wasn't produced in Central Russia, it was only occasionally brought from an area of the Caucasus in south west Russia, and sold in Moscow at a very high price.  Only the drink itself could be bought, and it was generally used as medicine.  At this time kefir was only for the rich, as common people could not afford the high price attached to this 'miracle drink'.

    The first mention of Kefir in literature I can find is: 'Сиповичъ. Сообщеніе о кефирѣ въ протоколѣ засѣданія Кавказск. Мед. Общ. 1-го Іюля 1867 г'.  This roughly translates to: Sipovich. Report on kefir in the minutes of the meeting of the Caucasian Medical Society, July 1, 1867.  

    Russian officials heard of the rumored health benefits of the nomadic Karachay people living around Mount Elbrus (in the Caucasus region), these stories combined with claims in the early literature mentioning the health benefits of kefir made it sound too good not to investigate further.  

    Historical texts vary a bit here, most documents refer to milk kefir coming from the North Caucasus, and a number of references are made to Khurzuk and the Karachay communities near Mount Elbrus.  All of them agree on one point: the region where the earliest kefir history is documented was within Russia. 

    To keep the people strong and healthy, the government wanted to obtain kefir grains and make kefir themselves.  Studies of the drink itself were always positive, but kefir can't be made without using grains.  To benefit the people and society as a whole, they hoped to make kefir themselves and eventually be able to make kefir available for average people.  

    Around 1907 or 1908 the All Russian Physicians’ Society (the name of this society varies a bit, and may have been translated slightly wrong) requested Nikolay Ivanovich Balandov, who was head of the Moscow Dairy, to source milk kefir grains.  The story goes that Balandov tried to buy kefir grains, and was refused multiple times.  He knew his chances of getting anything were low, so he sent a woman named Irina Tikhonovna Sakharova.  

    The idea was Irina would go with a team to the Caucasus, and she would charm a prince called Bek-Mirza Barcherov (I am not sure how to spell this name, or if he was even a 'prince', but he did rule over an aul) into giving her some kefir gains.  The prince was apparently quite taken by Irina, but there was strong tradition never to share kefir grains with outsiders, so he refused to give her any kefir grains.  Irina and her team eventually left to return home empty handed.  

    On her way home, Irina and her companions were stopped by the prince's men, and Irina was kidnapped to become the prince's bride.  This 'kidnapping a bride' thing was common in that part of the world at the time.  

    The rest of her party returned to Moscow, and petitioned the Tsar for Irina's release.  The Tsar intervened, ordered Irina's release, and demanded that she be offered adequate compensation.  This is where the story takes a twist.

    Irina could have asked for money or gold, but instead asked for kefir grains.  Not wanting to contradict the Tsar and start a war, these demands were begrudgingly met.  As compensation for being kidnapped, Irina was given around 4.5 kg (10 pounds) of milk kefir grains.  

    There is an alternate version of this story that is far less told, and far less romantic.  Shortly after arriving in Kislovodsk, Irina (accompanied by a factory manager) set out for a Karachay aul to visit 25 year old Prince Bek-Mirza Barcherov.  The prince supplied milk to the Balandov firm.  Barcherov was captivated by Irina’s beauty, and presented her with 10 pounds of kefir grains as a gift.  I don't know which version is true, but I can understand why this less incredible version would not be shared as widely across the internet.  

    In both versions of this story, the milk kefir grains were then taken to the Moscow Dairy, and studied and multiplied and divided.  Production of milk kefir was ramped up rather quickly.  

    The first milk kefir produced from these grains was given to patients at Botkin hospital.  Later it was sold through pharmacies as a health tonic.  

    While kefir was intended to be made as a medicine, it was so simple to produce that it was then sold in shops and (after kefir grains found their way out of the dairy) started to be made in people's houses.  

    By September 1908 the first bottles of milk kefir were sold in Moscow.  By the 1930s milk kefir was produced in large scale and was widely available across Russia.  

    Milk kefir and modern Russia
    Modern Russia has significant historical ties to milk kefir

    Kefir in archaeology

    Evidence level: Moderate

    Researchers recovered ancient proteins and microbial DNA consistent with kefir-like fermentation from ~4,000 year old tombs of Tarim mummies.  This has sparked many over-hyped and over-simplified reports of the Chinese making the world's oldest cheese.  

    The Tarim mummies were discovered in the territory of the Uyghur Autonomous Region, this is located in present-day Western China.  The story gets more interesting, as while this is in current day China the mummies are not 'Chinese' in the true sense of the word.  It has been determined that the mummies had blonde hair, a genetic trait that is remarkably uncommon/absent among genetically Chinese people.  

    While the tombs sit within the borders of modern day China, in times past various Siberian people and other groups also inhabited in that area.  While the ancient tombs are located within the boundary of present-day China, the people in these tombs were genetically South Siberians.  

    Current evidence suggests that the Tarim mummies had eaten something similar to kefir ie it had kefir proteins.  We don't know if they had kefir.  We don't know if the kefir of today descended from what was being consumed by the Tarim mummies, or if it was lost and the grains we use to make kefir today emerged some time later in history.    


    Religious references to kefir

    Evidence level: Weak

    Kefir and the Bible 

    Milk kefir is old, it has been around for a long time, and we don't know for sure when or how it was created.  While there are a few claims on the internet about milk kefir and the Bible, and there is a vague claim about milk kefir coming from Mohammad, it is unlikely that any of these claims are true. 

    Some people claim that kefir is mentioned in the bible.  Most of these claims are highly improbable, though not entirely impossible.  The bible repeatedly mentions eating 'curds' which may possibly be referring to kefir, but it probably just means they were eating curds.  

    Abraham lived to around 175 years old, which was not overly uncommon for people of that time.  The internet has a few pages that claim scrolls in Turkey exist which attribute Abraham's longevity to consuming kefir.  I am not sure that these scrolls ever existed.  Other than a few internet sites (which reference nothing), I can find no mention of these scrolls.  From Genesis 18:8 we learn that Abraham consumed milk curd, and it is safe to assume he likely consumed various types of fermented milk.  While it is not impossible he had kefir, it is extremely unlikely the kefir of today is descended from those grains.  Without finding huge numbers of references in historical literature, as well as strong religious traditions mentioning kefir, it is more likely that if kefir existed in Abraham's time, it later died out, and was recreated at a later date.  

    I have read internet claims that Noah received kefir grains from God to help him and his family survive on the ark.  I find this claim to be highly unlikely at best.  I am yet to find any source of this claim other than web pages that don't reference anything other than other web sites also making this claim.    

    Moses lived until about the age of 120.  Around 40 years of his life he was in the desert eating (among other things) manna.  There are some highly dubious claims online that manna was kefir grains.  Given that manna is described as tasting sweet, and kefir is best described as sour, this interpretation seems difficult to reconcile with the biblical description.  While we don't know for certain what manna was, it is likely that manna was actually secretions from scale insects.  

    Even if fermented milk resembling kefir grains existed in biblical times, there is no evidence linking it directly to the heirloom kefir grains used today.  

    Kefir and Islam

    There are a few internet sites mentioning kefir grains as being a gift from Mohammad to his people and/or to Orthodox Christians.  Many of these internet claims say the grains were a gift from Mohammad to his people and to Orthodox Christians.

    Kefir is not mentioned in Sunnah or Hadith, and kefir being a gift from Mohammad is not a universally held belief among Muslims, all of which immediately casts serious doubt upon this claim.  

    Kefir is not a common traditional religious food of all Muslim people.  Many nomadic Muslims produce and consume various other types of fermented milk instead of kefir.  There is little evidence that kefir occupies a unique or honoured place across Islamic tradition today, which further weakens claims that it was universally regarded as a gift from Muhammad

    It seems illogical that Mohammad would only give this gift to Orthodox Christians, and not to his own people as well.  Again this part of the story casts serious doubt on this claim.  

    I am not certain, but don't think Mohammad travelled into the Caucasus mountains or any part of south west Russia (which is the location of the first modern historical references to milk kefir).  It would be more likely that if kefir grains came from Mohammad, they would have entered the world somewhere else, and spread from there.  

    I also found IslamQA which states they "haven’t come across any authentic narrations citing the incident above".  While I don't know how reliable that site is, the response was prepared by Islamic scholars. 

    For the above reasons, I find it highly unlikely that Mohammad giving the grains to his people or to Orthodox Christians could be the origin of kefir.  The only thing that gives this story any weak credibility is that milk kefir recently came from the Caucasus region, which is Muslim dominated and would have had Orthodox Christians in early years.  The part about Mohammad not travelling there makes this story difficult to reconcile with the historical evidence currently available.


    Scientists can make kefir grains (but not the ones people use at home) 

    Evidence level: Strong

    Contrary to a common internet claim, scientists have successfully produced kefir grain-like microbial structures capable of fermenting milk.  They are not identical to the heirloom grains used today, but they demonstrate that kefir grains are not beyond scientific understanding.

    There are several published, peer reviewed papers where kefir grains have been reproduced, either entirely artificially, or by using somewhat natural methods (such as this, or this, and this). 

    These incorrect claims of scientists being unable to make kefir grains are possibly because most kefir sold in supermarkets is not usually made using grains.  Supermarket kefir is usually made by adding a very small number of isolated strains to milk.  This is not because scientists can't make kefir grains.  

    Commercially produced kefir not being made with grains has nothing to do with scientists' ability or inability to make the grains, its about keeping everything uniform. 

    Instead of making kefir by using traditional grains, commercial kefir is usually made by adding a few isolated strains to milk.  Using a very small number of isolated strains ensures consistency of the final product, and makes it easier to batch test for safety.  Kefir made with grains often has vastly more cultures than store bought kefir, but it is different each batch, it changes from season to season.  Foods need to be tested to ensure safety.  Kefir made with grains is very safe, yet it is difficult to test each and every batch to demonstrate its safety, so it is not usually made this way commercially.  

    The grains available to home fermenters were originally family heirlooms, passed down through generations.  While kefir grains you get from one person will be slightly different than grains you get from the person next door to them, they are still kefir grains.  

    Even though scientists can make kefir grains, you cannot get kefir grains that descended from the ones that were originally made by scientists.  The heirloom grains passed between home fermenters remain the traditional way of making kefir.

    What We Know (and What We Don't)

    What we know

    • Kefir was documented in the North Caucasus region of Russia by the nineteenth century.
    • It spread to wider Russia in the early 1900s.
    • Irina Sakharova played a central role in that story.
    • Kefir grains are living microbial communities.
    • Scientists have successfully created kefir grain-like structures.

    What we don't know

    • Exactly when kefir grains first formed.
    • Whether today's grains descend from ancient fermented milk cultures.
    • Whether biblical or religious stories have any historical basis.
    Unlike written history, microbial communities don't leave an easily traceable fossil record, so finding the source of the very first kefir grains is extraordinarily difficult.

    Kefir Today

    By the late twentieth century, kefir had spread well beyond Russia and today is produced around the world.

    There are various companies mass producing and selling what they call kefir.  These fermented milk drinks are marketed as kefir, but they are usually produced using a few isolated bacterial cultures rather than traditional kefir grains.  There are also some sachets that are used to make fermented milk, this is meant to taste vaguely similar to kefir.  Commercial kefir generally contain far fewer microbial species than traditional grain-fermented kefir, and is manufactured for consistency rather than wide microbial diversity.

    After looking through the myths, archaeology, scientific papers and historical records, one thing becomes clear: the real history of milk kefir is fascinating enough without embellishment.  We still don't know exactly where kefir grains first appeared, but we know considerably more than many websites suggest, and the documented journey from the Caucasus to modern kitchens is remarkable in its own right.

    I cover with a strainer, but a cloth also works

    Why the origin of kefir grains is such a mystery

    Unlike yoghurt cultures, kefir grains are complex self-organising microbial communities.  They don't fossilise easily, they weren't deliberately invented, and before the nineteenth century almost nobody wrote about them. 

    That combination makes tracing their true origin extraordinarily difficult. 

    Where to get kefir to ferment at home

    If you want to try fermenting milk kefir at home, you need to get some kefir grains.  These are not a type of 'grain', it is just their common name.  Much like a sea monkey is not a type of monkey, and a sea horse is not a type of horse, milk kefir grains are not a type of grain.  

    Milk kefir grains are complex and ever changing colonies of beneficial bacteria and yeasts growing in a matrix of kefiran.  Kefiran is a microbial exopolysaccharide and is thought to be incredibly beneficial, this is often missing from commercial kefir flavoured drinks.  Milk kefir is super easy to make, while slightly more work than filmjölk, it is about the same effort as kombucha.

    If you want to try making milk kefir yourself, For Australian readers, if you want to try this yourself, I sometimes sell traditional milk kefir grains.  My kefir grains are heirlooms, they contain living microbes, and they will live longer than you if they are looked after.

    Micro Tom tomato history

    I have been growing Micro Tom tomatoes for a short time now, over that time I have grown several generations of them, saved pure seed, and crossed them with various other tomatoes to try and create new micro tomatoes.  Micro Tom tomatoes are a delightful little plant, the more I grow them the more I like them.

    I have read a few different things about Micro Tom on the internet, unfortunately much of it is very different from my observations.  I thought I would write a blog post to clear up some confusion about Micro Tom tomatoes.
    Micro Tom tomatoes
    Where did Micro Tom come from
    Micro Tom has been declared as the world's smallest tomato variety.  It was released from the University of Florida in 1989 where it was developed by Dr. J.W. Scott and Dr. B.K. Harbaugh.

    I have read various people on the internet claiming that because Micro Tom was bred at a university that it must be a Genetically Modified Organism (GMO), others that say it is not, some that say it is a hybrid, some that say F1, others that say Micro Tom is open pollinated.  So I did some research on Micro Tom tomatoes.

    The truth is that Micro Tom is a stable tomato variety which is as stable as any other tomato variety, it can be grown open pollinated and seeds will grow true to type unless it is crossed with another variety.  Micro Tom is NOT a GMO and was bred conventionally in the same way as almost everything else that you have ever eaten.  The reason Micro Tom grows so small is due to at least three different genes that were bred into it conventionally, the same way that red colour was bred into tomatoes.  These three genes were all spontaneous mutations so nothing untoward has gone on here.


    How is Micro Tom so small
    Micro Tom has a combination of three different genes which make it grow tiny.

    One gene is for dwarf growth that is common in dwarf tomatoes, it is most likely d.  Strangely this dwarf gene also has a mutation in Micro Tom, but that is a rather complicated story for another time.

    Micro Tom has the self pruning gene which is responsible for creating determinate tomato plants, it is most likely sp.

    Micro Tom also has the sun dwarf gene which creates extremely short internodes under high light intensities, it is most likely sd.  I assume that if grown in low light then Micro Tom would be a bit taller, but even when grown in winter my plants are always under 10cm tall.

    All three of these genes are recessive, which makes breeding new micro tomatoes using Micro Tom as the female parent a reasonably straight forward process.


    How productive is Micro Tom
    I have read a lot of differing views on the productivity of Micro Tom tomatoes.  Various seed sellers have the following listed on their web sites:
    • "produces a crop of around 40-plus cherry tomatoes per plant"
    • "bear 1-3" good flavored tomatoes in heavy quantities"
    • "The plants are suprisingly productive, a 6" plant can produce up to a couple dozen fruits."
    • "is loaded with tasty fruit"
    • "bearing loads of flavorful, 1 oz., deep red fruits"
    • "Plant produces good yields of tiny pea size red tomatoes"
    • "I am able to harvest about 20 - 30 tomatoes from this plant growing in a 6in pot"
    My growing conditions are a lot more harsh than most, so perhaps I get less fruit per plant than I could.  I dare say that your growing conditions are also not perfect.  Keeping that in mind, I would not consider any of the above reviews of crop size to be accurate.

    I normally get around 10 tomatoes per tiny Micro Tom plant.  Sometimes a few more, sometimes a few less.  If I used fertilisers and coddled the plant I think I could get around 20, but I am happy with it producing 10.  I certainly would not say that it is 'loaded' with fruit or produces 'heavy quantities' or produces '40 plus' tomatoes.

    I also found a Japanese research company that sells Micro Tom seeds to scientific organisations for the purpose of genetic research, they said "It yields about 20-30 seeds per fruit. One plant yields about 200-300 seeds"  in other words, about 10 fruit per plant, much the same as I am getting.


    How tall does Micro Tom get
    The internet seems to have a large range here.I have found reference on the internet to the following:
    4-7 inches, 4-6 inches, 5-8 inches, 6-8 inches, under 12 inches, 8 foot (I hope that this one is a typo and they meant inches).

    My Micro Tom plants are all descendants of one old seed, so the genetic pool with which I work is rather narrow and may not be indicative of overseas strains.  Personally I am yet to have a Micro Tom plant reach 10cm (about 4 inches).  Mine have all grown between 4cm and 9cm tall.  Growing in a cup of soil or in the garden has not changed the height noticeably.


    What size is Micro Tom fruit
    This is one of the claims on the internet that makes me think that many seed sellers have never actually grown the plant themselves, and don't care enough about the buyer to bother putting accurate information.  Many have gotten confused when they read about micro dwarf and think it is talking about fruit size, when it is talking about the height of the plant.  I have found reference on the internet to the following:
    • "pea size"
    • "cherry tomatoes"
    • "1-3 inch"
    • "1 oz deep red fruit"
    • "1 inch fruit"
    "Pea size" being the most common fruit size that I saw, but probably the furthest from the truth, although I can not even begin to imagine a 3 inch (7.5cm)  tomato fruit on a 4 inch (10cm) plant!!!

    My fruit are reasonably consistent in size, around 2cm, this photo shows how large they are for me.  I have given seeds to a few other growers, they all report Micro Tom tomatoes mostly being about 2cm.

    How many days to maturity for Micro Tom
    This is another weird one when you look up what the internet says.  I have found the following listed on various seed company's web pages:
    Days to maturity: 50, 60, 120  
    Days from seed germination to ripe fruit: 50, 60, 70 
    Days from transplant when grown under lights in winter/early spring, 39, 75-85, 70-90, 88.

    As you can see, that makes no sense at all when you try to compare the same information on different web sites.

    The first time I grew Micro Tom I recorded around 113 days from planting the seed until harvesting the fruit. Then I grew it a few times without recording the dates.  This last time I recorded 97 days from planting the seed until harvesting the first ripe fruit.


    What does Micro Tom tomato taste like
    They are ok, Micro Tom lack any real depth of taste and will not be anyone's favourite tasting tomato variety.  They taste much nicer when ripened in warmer weather than they do in cooler weather, and at some times of the year they taste a bit nicer than cherry tomatoes that I can get from the shops.  While Micro Tom is certainly not the best tomato you will eat they are far from the worst.  I have never seen someone who ate one and disliked it. 


    More people should grow Micro Tom tomatoes
    I really like Micro Tom tomatoes, the plants are tiny and the fruit tastes ok.  I don't see the point in exaggerating when describing plants.  If people want to grow them, then they will grow them even if they do not produce millions of fruit on a tiny plant.  I have shared seeds with several seed savers and a few dedicated growers.  I also list organic seeds for sale on my for sale page when I have enough to spare.  At this stage this is the only place in Australia to get Micro Tom tomato seeds.
