Simple Kombucha continuous brew recipe

Very simple Kombucha (чайный гриб) continuous brew recipe 

I wrote an earlier blog post on kombucha SCOBY and described what a scoby is compared to the pellicle and starter liquid.  That post started to get a little long so I decided to stop there and write a separate post on the kombucha recipe we use.  

There are plenty of kombucha recipes on the internet.  They pretty much all work because it is actually hard to go wrong brewing kombucha when you use both pellicle and starter liquid. 

I am not suggesting that the way I brew kombucha is the best way to do it, or even a good way to do it, I am only saying it is simple and it works for me.  This blog post is partly a way for me to record this in case I ever forget how to do this in the future.

Continuous brew чайный гриб

I tend to do continuous brew rather than messing around with batches and bottling and using fridge space.  Continuous brew works for me, it never goes wrong, I don't see how it could go wrong, and it takes very little time and effort.  

Some people much prefer batch brewing.  I hear about these going wrong from time to time.  Apparently the issues with batch brewing are simple enough to avoid.  I can't offer any advice on batch brewing or flavouring kombucha because I don't do that.  

Continuous brew and batch brew are both good methods, which one to use is more about personal preference than anything else.  The scoby doesn't care if you do continuous brew or batch brew, you could try both and see what you prefer.  

Kombucha ready to drink

Kombucha looks like beer or apple cider

I have a large glass jar with a tap.  This jar contains one or more pellicles and some finished kombucha/starter liquid.  

I drew two lines on the jar, one at 4 liters, the other at 6 liters.  I fill it up to the 6L line, we drink it as wanted and I refill it once it drops to the 4L line.  It is simple, and a little inconsistent, but can never fail unless there is some mechanical failure such as the jar gets smashed or the tap falls out.  

I don't put the lid on the jar as the scoby needs some air.  Instead I tend to keep a cloth on top of the jar, this keeps out insects and dust.  I used to hold the cloth on with a rubber band, but stopped bothering with that a few years ago and the cloth just sitting on top still does the trick.  

Continuous brew чайный гриб recipe

Once we drink enough that the liquid drops to the 4L line I fill it with sweet tea that has cooled.  Never use hot tea as this will kill (or at least damage) the scoby. 

  1. I boil 2L of water, add 1/2 cup white sugar, and 2 or 3 tea bags.  I mostly use regular black tea bags, but sometimes also include a bag of green tea.  
  2. I let this steep for about 5 to 15 minutes, then remove the tea bags.  
  3. I let this cool to room temperature.  
  4. Once cooled I pour this sweet tea in my jar, and it is ready to drink in a few days (or immediately if you prefer it sweeter).  
Let me stress that I always allow it to cool before adding it to my jar, never add this when still hot or it will kill the scoby.  

Some people use more sugar while others use less sugar, some people use more tea bags others use less tea bags.  Sometimes I use some black tea and include some green tea, other times I only use black tea.  I use tea bags so I don't have to strain out any leaves, using loose leaf tea would also be fine as long as you can strain out the leaves.  

If I go away for a while I just fill it up and it is fine when I return.  I don't have a lid on my jar so there is no risk of building too much pressure.  The contents of the jar are too acidic for most pathogens to survive, so there is no danger there.  A pantry moth or something could get in and I would have to deal with that, but that hasn't happened here yet.

Continuous brew kombucha simply works, you can't really go wrong as long as you let the tea cool before adding to the jar and the scoby is strong. 

Continuous brew kombucha, I keep a cloth on top 

My jar already has a pellicle, and 4L or so of starter, so it brews quickly and is ready to drink in next to no time.  I hear of other people having to wait two weeks before their brew is ready, they tend to use significantly less starter liquid than I do.  

Sometimes when we are drinking a lot of kombucha this drops a bit below the 4L line before I have a chance to refill it, that doesn't really matter.  Other times I refill before it reaches the line, again this doesn't really matter.  Over summer it brews a lot faster, over winter it brews far slower.  This is not a precise science.  

Most recipes suggest adding a pellicle and 10% starter liquid to 90% tea, this works fine but is a lot slower than how I do it.  I use about 66% starter liquid and about 33% sweet tea, and it brews very fast.  We tend to drink some kombucha most days, so want to fill my jar and have it ready to drink as soon as possible.  Sometimes my kids drink it as soon as I filled it, I prefer to wait a few days as I like the sharper taste.

It usually has more bubbles

While my method may not be the best way to brew kombucha, the fact that I can keep a continuous brew going like this for a few years is testament to the fact that this method is working.  Perhaps there are better methods, but this works for me, and it is so simple. 

If you have a kombucha recipe that is different, and it works for you, please keep using it.  If you try one recipe and don't love it, then change it and try something different.  One of the best parts of kombucha is nothing is precise, and you really can't fail.  

If you are new to brewing kombucha, it is difficult for anything to go wrong if you brew using both pellicle and starter liquid.  Some people discard the pellicle from every batch, which works for them, but when first learning how to do this it is best to include the pellicle as well as the starter liquid.

чайный гриб has been brewed by people at home since at least the 1800s, it is simple and inexpensive.  I have never used a heat mat, I don't have a thermometer, nothing is overly precise and nothing ever goes wrong.  At worst I leave it too long before drinking and it tastes a little too sour for my liking.  

If you want to try brewing kombucha at home, you could try using unflavoured kombucha from the shops.  This will likely have a significantly lower number of strains and you can't be certain it has not been pasturised (killing many of the bacteria and yeasts) prior to sale.  You are better off finding someone who brews kombucha and buying a scoby (not just a pellicle) from them.  If you can't find any locally, and you are located in Australia, my contact details can be found on my for sale page.

Kombucha (чайный гриб) SCOBY

For a few years we made чайный гриб (pronounced as chai-knee grib).  This translates to tea mushroom.  The beverage itself is sometimes known as grib “mushroom”.  I have read on the internet that it is also affectionately called gribok “little mushroom”, but have never heard anyone use this term.  Most people in Australia call this drink kombucha. 

Kombucha is sweet tea that has been fermented using SCOBY.  If you make kombucha at home it is cheap and surprisingly simple to do.  Many people flavour it with various things, while some of these are nice I prefer to drink it as is without flavouring.  

SCOBY is an acronym for Symbiotic Culture of Bacteria and Yeast.  Various studies have been done to count the number of species present in the scoby, while these numbers range dramatically depending on the scoby tested (and keeping in mind that each scoby will gain and/or lose species as time passes), kombucha often contains around 200 species with 20 bacteria and 16 yeast being the most dominant

People often like to think that symbiosis means all the organisms working together in balanced harmony to benefit each other.  The truth is far less romantic.  Symbiosis only means different organisms living together for a period of time, symbiosis does not have to be mutually beneficial, or even beneficial at all.  

In kombucha, all the organisms are competing for survival, some of them benefit from this arrangement, others less so, some even entrap and almost 'farm' others.  These organisms competing for survival make the environment too harsh for non-beneficial organisms, while adding health benefits to the drink.  It is a fascinating subject that is poorly researched, and no two scoby's are exactly the same.  

kombucha jellyfish

For some inexplicable reason there is a growing number of people who like to argue (looking at you Reddit) over what exactly is the 'SCOBY' in kombucha.  It seems like semantics to me.  They will also aggressively demand that scoby is written all in capitals because it is an acronym, they are correct on that point, but I find it harder to read when all in capitals so tend to use lower case. 

Kombucha pellicle

When making kombucha at home it often has a pellicle.  The pellicle is a flat thing that looks a bit like a pancake, or a jellyfish, (or a placenta).  Some people refer to the pellicle as the scoby, while others aggressively attack them for using this term as it is not strictly accurate.  

The pellicle is made of cellulose that is built by bacteria.  The scoby lives in and on and under the pellicle, you could not separate them if you tried.  The pellicle helps to protect the scoby, and helps the scoby survive if conditions are not ideal.  Kombucha pellicles have been tested in the international space station to see how it protects against radiation etc - it is a fascinating subject.  We don't fully understand how the pellicle works, or exactly what it does, but we know it has a role for the microorganisms interacting with each other.  While the pellicle is not the scoby, I don't see much harm in calling the pellicle the scoby, to me it seems like semantics.  

While certainly not ideal, it is possible to brew kombucha by simply adding the pellicle to sweetened tea.  This is possible, and I have done it, but things could go wrong.  The main problem is the liquid will generally not be acidic enough to prevent other microorganisms from growing.  Another issue is most of the scoby are in/on the pellicle rather than mixed through the liquid.  If starting kombucha with only using the pellicle, by the time enough of the scoby are in the liquid and the pH is low enough there are also many other microorganisms who have started to grow.  For this reason you should always include at least some starter tea when brewing kombucha.  Most people add about 10% starter to 90% sweet tea but I include a lot more.  You could only use the pellicle and add something acidic to lower the pH, but it is easier and better to just include some starter tea.  

Kombucha

Kombucha starter tea

Some people refer to the kombucha liquid that you drink as the SCOBY.  Again, this is not technically true.  The liquid is tea and waste products after it has been partly digested by bacteria and yeast (it sounds gross, but it is good for you).  The scoby lives in this liquid, and feeds off this liquid, and you could not separate them if you tried.  While the liquid is also not the scoby, I don't see any harm in people referring to the liquid as the scoby, again it seems like semantics.  

It is possible to brew kombucha by simply adding some starter liquid to sweet tea.  I am told the finished kombucha brew tastes different than when the pellicle is also added.  

Fermenting kombucha using only the liquid and no pellicle works well enough because this liquid is too acidic for many harmful microorganisms to thrive, the scoby are mixed through the liquid, and the scoby can multiply quickly and make the environment too harsh for other microorganisms to get a foothold.

For those who disagree with me that the pellicle acts as biofilm and can be used effectively as an inoculum, I thought I would include a link to a paper on this topic and quote some relevant parts.

https://pmc.ncbi.nlm.nih.gov/articles/PMC8371556/#:~:text=Kombucha%20pellicles%20are%20often%20used,part%20of%20the%20kombucha%20consortia.

The below talks about what the pellicle is, the different layers, and the role of entrapped yeasts: 

The kombucha biofilm presents similarities to cellulosic pellicles grown by pure acetic acid bacteria (AAB) in sugared black tea but differs by the presence of yeast, which are involved from the early steps of biofilm formation. Based on observations, the formation model consists in an initial trapping and aggregation of yeasts (possibly in pseudo-mycelium form) in bacterial cellulose. With accumulation of cellulose and cells, a consistent layered pellicle is formed and, from then on, grows in thickness. The top layer at the interface with air is made of parallel cellulose fibrils and hosts yeasts and bacteria, while the bottom surface at the interface with liquid is made of cellulose network colonized by bacteria and where biomass accumulates. Finally, a middle layer located under the top cellulosic layer is filled with biomass and viable bacterial cells that are suspected to be the active agents of pellicle growth. This region is thought to play a nutritional function for bacteria by taking advantage of entrapped yeast metabolism and autolysis, thus revealing an aspect of the microbial interactions in kombucha. This study indicates that the yeast–AAB interactions in kombucha act on the structure and building of the pellicle, which could, in turn, enhance other types of interactions, including the metabolic interplay necessary for optimal kombucha production.

Some people brew kombucha without ever using a pellicle, and throw away every pellicle they see.  While this seems to work for them, for a beginner I would not recommend it.  Brewing kombucha using both starter tea as well as the pellicle is very simple, and it has been demonstrated to produce a healthy result.  Using both pellicle and starter tea is the traditional way to make kombucha, and it is really hard for anything undesirable to start growing.  

For someone who is just starting out brewing kombucha, it is easiest to use both pellicle and starter tea.  The pellicle and the starter liquid both contain live SCOBY, and including both when brewing kombucha is simple and gives a beginner no real way to fail.  Including both the pellicle and the starter tea ensures you will have the maximum diversity of microorganisms, it will have the maximum number of beneficial microbes, and it gives the best chance that they will be interacting in ways you want them to.  

Once you have done a few kombucha brews and have a feel for how things should progress, as well as what looks normal, feel free to discard the pellicle and only brew using the liquid (which is simple), or to only use the pellicle (but only if you are very confident you know what you are doing).  When you are still learning, however, I strongly suggest using both the liquid and the pellicle.  

If you are new to kombucha, and are buying scoby to get started, don't just buy a pellicle.  Make sure you get pellicle and some of the starter liquid.

There are plenty of kombucha recipes on the internet.  They all work because it is hard to go wrong brewing kombucha when you use both pellicle and starter liquid.  

I tend to do continuous brew rather than messing around with batches and bottling and using fridge space.  Continuous brew works for me, it never goes wrong, and it takes very little time and effort.  

Other people prefer batch brewing.  This works for them, and they are happy with the result.

They are both good methods, they both work well, it is just personal preference.

You can see in the photo above I have a large jar that has a tap.  It is simple, and can never fail unless the jar gets smashed or the tap falls out.  

I don't put the lid on the jar as the scoby needs some air.  I tend to keep a cloth on top of the jar, this keeps out insects and dust.  I used to hold the cloth on with a rubber band, but stopped bothering with that a few years ago and it still does the trick.  

This blog post is getting a little long.  At some stage I will try to write another blog post with the kombucha recipe I use.

Milk Kefir Bottle Strainer

Years ago I got some milk kefir grains, and we made milk kefir regularly.  

Milk kefir is kind of like a thin drinking yogurt, it has been around virtually forever, and is very good for health.  Kefir contains vastly more probiotics than yogurt, it is simpler to make than yogurt, and once you have it you can keep it going for ever as long as you have access to milk.  

Back when I was first making kefir there was very little information on kefir on the internet.  From memory there was a web page by Dom Anfiteatro (which seems to no longer exist) and basically no other internet sites mentioned kefir at all.  Things have changed a lot since then. 

At that stage lots of people made kefir at home, but no one really spoke about it.  There was no kefir (or kefir flavoured milk) available at supermarkets back then, and it seemed like no one had thought of selling those dreadful starter satchels.  

Kefir bottle strainer

I drank our milk kefir most days, and it was good.  We then moved house and bought the kefir grains with us.  Back then we had access to raw milk from a dairy, so making kefir was very cheap.  

Years later we moved house again, once again we brought the kefir grains with us.  As we no longer have access to a local dairy, milk kefir started to cost a lot more as store bought milk is expensive.  

I used to use a kitchen strainer to separate the grains from the milk.  When the kefir was thicker than normal or had a lot of curds I found it difficult to strain through the fine mesh.  I started to find that cleanup was bothersome and my strainer was starting to fall apart from old age. 

The cost of milk, combined with the hassle of clean up, plus being busy in general, meant I eventually let my kefir grains die.  I regret that, it was a mistake.  Don't ever let your kefir grains die.

Our kefir from years ago: Milk Kefir on left, Water Kefir on right

I missed kefir, so not too long ago I decided to get milk kefir grains again.  Milk kefir is very simple to make, you can't really do it wrong.  

To help with clean up, I got a cheap can strainer.  I figured this would be fast to use and simple to clean.  

Kefir can strainer

I won't be making a lot of kefir to begin with.  Perhaps a few cups or so for now.  This amount fit easily in a small jar.  

This strainer is made of silicon (or silicone, I can never remember how to spell this), and fits neatly on the end of a jar.  The holes are large enough that I thought it should strain thicker kefir much faster than the fine mesh strainers.  The holes also seemed small enough that I thought they should be able to retain most of the larger kefir grains.  

The bottle strainer was very cheap, and the jar was free.  Making kefir is simple, I don't know why people try to make it more difficult than it needs to be.  Kefir was made by generations of nomads using bags made of goat skin or horse skin, there is not need for much expense or high tech equipment when making kefir.

I found a solid lid to keep out dust and insects

The other day I saw a kefir kit for sale at the supermarket.  This kit sells for $35 (plus postage if you cannot pick up in store).  This seemed overly expensive for what it is.  

That price only includes a jar, a strainer, some instructions, and a weird wooden spoon.  Even at this high price it does not come with any kefir grains.  My can strainer on the end of a jar should work much the same as the pre made expensive kit.  

Massively overpriced kefir making kit (not my photo)

This lid is prettier than mine (not my photo)

To get an idea if my strainer would work I looked at reviews for the kit online, but none seemed to be written by anyone who had used them for any length of time.  Some reviews speak of how their kefir tasted, or how the instructions were simple to follow, but few mentioned how well the kit worked.  How strange.

The jar I use was free, the strainer cost under two dollars including postage, I already own various spoons, and (while I don't need instructions) anyone who sells grains sends instructions or instructions can be found online for free.  My set up is similar to the kit, but cost me a tiny fraction of the price.  

I figured I would give this can strainer a try and see how it works.  Now that I have used this for a while I figured I would write a blog post explaining how it worked for me.   

Bottle strainer should be good for milk kefir

After using the strainer for a few days it was obvious that it doesn't work well enough.  It is a great idea in theory, but doesn't work well in practice.  I pushed on and kept using this to see if it got easier with time, and it didn't.  It looks like it should work a treat, and I really wanted it to work, but it isn't the best tool for the job.  

Over summer my kefir seems to get thick curds within a few hours of adding the grains to the milk.  I could probably have more milk to less grains to make it thinner, but I don't want to do that.  Much more importantly, the kefir grains also clogged up the holes and prevented any liquid from flowing through. 

The liquid would not go through the can strainer without being stirred constantly.  I tried first mixing the curds and grains through the liquid and then immediately tipping the kefir through the strainer, but it still didn't work well.  The grains almost immediately block all the holes, and the kefir would not go through the jar strainer without being stirred constantly.  What a hassle! 

Stirring got the grains off the holes and it made the liquid go through the can strainer easily while I was stirring, and it stopped going through when I stopped.  Stirring kefir while it was in the can strainer is more difficult than just using a kitchen strainer.  It worked, but was not overly practical.  Eventually I got frustrated and looked for something else to use. 

I found it a lot faster and easier to tip the kefir through a tea strainer that we already have.  The mesh is very fine, but I can stir it with my finger or a spoon, which is enough to make the kefir go through quickly.  I sit this tea strainer in a coffee mug which catches the kefir.  The fine mesh means it captures all but the tiniest of grains, retaining tiny grains has meant my grains have divided and increased faster.  

I don't love using metal with kefir, but stainless steel is meant to be ok.  The grains are only in the strainer for under a minute each day, and most of them are not in contact with the metal at any point, so they seem to be coping well and multiplying fast.

can strainer vs tea strainer

Cleaning the tea strainer after using it for kefir is simple and fast.  After tipping the kefir through I scoop the grains out, and then run the strainer under the tap for a few seconds.  That seems to be enough to clean it well.  This only takes a few seconds.  

I plan use the tea strainer for now, but my grains quickly multiplied to the point where they no longer fit in it and the jar I am using does not hold enough milk.  I find kefir grains multiply well in the warmer months, and not so well when it is cooler.  

Soon I will use a larger jar, and spend a few dollars and get a plastic kitchen strainer with fine mesh like I used to use.  We don't have one of these at the moment, but they shouldn't be too expensive.  

This is the type of strainer I previously used (not my photo)

I already have some very large jars that used to hold pickles or olives or something, so this won't cost me anything.  Instead of tipping the kefir into a mug I will use a bowl or something that we already have.  Other than a few dollars for the strainer, and buying milk, it won't cost anything to make kefir.  

Making milk kefir at home is very simple, and there is no need for it to cost a lot of money other than a once off purchase of grains, and buying the milk.  

Milk kefir bottle strainer - may work for water kefir

As mentioned, the can strainer seems like a good idea but is not well suited to straining milk kefir.  I also don't think the expensive milk kefir kits would work any better for milk kefir.  Or maybe they do work, but only if you use satchel starter instead of grains, in which case I don't know what you would be straining.  To be honest, I don't understand why you would bother making kefir using stater when grains are so much cheaper and vastly superior to satchel stater, but that is a topic for another time.  

This strainer looks like it might work well when making water kefir.  Water kefir is different to milk kefir, there are no curds or thick liquid to deal with, it is just the grains and the liquid.  Or perhaps the water kefir grains will clog the holes and it won't work, I don't know yet.  I plan to try using this can strainer with water kefir for some time and write another post on how it performs for me.

Kombucha Continuous Brew

We have been keeping various ancient cultures for years.  We started with milk kefir, then went on to things such as water kefir and sour dough.  Some cultures we have kept going for years, others we have lost, and others we decided to stop doing for now due to various reasons.  One of the cultures we have at the moment that I really enjoy is kombucha.

Unfortunately the origin of kombucha has been lost to history.  Several romantic theories have been made about the origins of kombucha, none appear to be based on anything other than dramatic story telling, and these stories eventually merged to the one that is often told today.  The truth is that we know roughly where kombucha originated, we know vaguely when it started to become popular, but it doesn’t make one ounce of difference.  The drink tastes good, it is simple to make, and it reportedly has several health benefits.  Who really cares when or how it was discovered.

I thought I would write a blog post to share the down sides of continuous brew kombucha, and test some of the health claims.  I think you may be surprised by the results.
Kombucha scoby continuous brew
Continuous brew kombucha

Early this year a very generous person gave me their beautiful continuous brew kombucha set up.  This thing is amazing.  It is large enough to make decent amounts of kombucha, and other than drawing off liquid and filling it up when low the system pretty much takes care of itself.  I have no idea if continuous brew is as good as batch brewing, but it works well for us so I am happy with it.  There have been two down sides to continuous brewing kombucha so far.

Firstly, and unimportantly, my scoby is not as pretty as the ones I see on the internet.  On the internet they always look like a perfect neat pile of fluffy pancakes floating blissfully in clear tea.  My scoby looks more like a pile of pancakes that was quickly eaten and immediately puked up by a donkey.   I am sure I could remove the messier ones and make it look prettier for a short time if I wanted to, but it would soon get back to looking like this.   It does its job well, so it doesn’t matter what it looks like.

Secondly, the only important down side I have noticed is that the little tap gets clogged from time to time.  The tap had a little mesh filter behind it, I removed that filter and it has never clogged since.
 
Kombucha scoby, mine doesn't look as pretty as the ones I see on the internet!

There are many anecdotal reports about the health benefits of kombucha, these range from things that seem reasonable to utterly absurd exaggerations that only a fool would be taken in by and everything in between.  Some health benefits have been scientifically tested, while others have not.   Some of the more commonly reported health benefits include decreased blood pressure, evening out of blood sugars, improved digestion, weight loss, increase in general immunity, lowered levels of anxiety and depression, and improvement in overall health.

Some of the alleged health benefits would be lovely, while others would actually be bad for me.  Decreasing blood pressure would be dreadful for me as I already have low blood pressure.  It is possible that kombucha helps even out blood pressure, but the people who rave about it mostly have high blood pressure?  Or maybe it has no noticeable effect on blood pressure and this is one of the many false claims?  I don’t know, so I decided to just drink it and see how I went.

Nothing works immediately, if anything is actually going to actually make you healthier it is going to take time before you can notice the difference.   When you notice the difference straight away it is often not going to do you a great deal of good long term (such as in the case of pain killers or antibiotics) or it is a placebo.   For the past few months I have been drinking kombucha most days.

So how do I feel after drinking kombucha for around six months, and how does that compare to before I started to drink kombucha?
kombucha continuous brew
Kombucha - the lines let me know when to refill

Unfortunately I have to admit that I feel exactly the same as I did before I stared to drink kombucha.  That's disappointing and unexpected.
 
My digestion is no better or worse, my general immunity is no different than before, my blood pressure and blood sugars are the same as always, and my overall level of health has not been altered one bit.  I was not expecting that.

I would love for kombucha to be a cure all tonic that made me as fit and strong as I was ten years ago, but it is not.  This doesn’t matter, I plan to keep brewing and drinking kombucha simply because I like it.

I don’t know if kombucha ever improves people’s health, maybe it helps some people but not others.  Perhaps my health made no improvement as I was relatively healthy to begin with.   I have issues with my neck and back due to an injury, I have low blood pressure and I need to keep an eye on my blood sugars (I have almost cured myself of blood sugar issues), but I eat well and am not sick all that often.  I don’t eat a lot of processed food and I sometimes drink water kefir so my gut flora is probably well established and robust.

Maybe kombucha improves the overall health of people who are generally unhealthy, eat poorly, and have imbalances in their gut flora.   I will continue to brew and drink kombucha simply because I like the taste, any health benefits that I may be getting from it are just a bonus.
Kombucha taste good to me

I should put up a post with the recipe for how I make kombucha, partly to help others but partly in case I ever forget.  The recipe I use is really simple and takes very little time.   When I do write a post with the recipe I will try to remember to link to it from here.

I don’t currently sell kombucha starter scoby through my for sale page as I am concerned about how it is covered under food safety laws.   I know that it is virtually impossible to legally sell eggs at markets in Australia due to food safety laws, I assume kombucha is probably restricted in similar ways.

Yacon Water Kefir


I have had milk kefir grains for some time now, the kids love it, I like it but find it a bit too sour to drink by itself, and Tracey dislikes the taste of it.  Kefir is good for you so I wanted to try water kefir.  Perhaps that would be a way for the kids to get more of the kefir goodness into their diet.

Recently we obtained some water kefir grains.  Water kefir is different from milk kefir, it is still very good for you though.  The younger kids do not like water kefir all that much (mostly because it is a bit bubbly), Igloo loves it, I love it and Tracey thinks it is ok. 

Kefir
Both types of kefir contain live and beneficial probiotics.  Basically they consist of "good" bacteria, yeasts and other microbes. These good microbes are eaten by you and some will colonise in your digestive tract and continue to provide you with benefits long after you have finished consuming the kefir.  There are many recipes for water kefir on the internet but we have been mostly following the one that came with the grains.

Yacon
Yacon contains inulin and other sugars which are not digestible by humans.  Yacon is considered a prebiotic, this means that it contains things that feed the good bacteria etc in your digestive system which help to keep you healthy.  Yacon tubers also taste great, it is a vegetable that is eaten like a fruit and is loved by kids.  Yacon is my favourite vegetable.

Kefir & Yacon?
If water kefir contains probiotics, and yacon contains prebiotics which feed the probiotics, then it made me wonder if I could culture water kefir on yacon and leave out all of the other things.  After internet searching I found many people who claimed water kefir flourished when using yacon syrup instead of sugar.  Some people culture water kefir only on water and sugar, many of these people were the ones saying that the yacon syrup was great.

The only problem is that I do not have access to yacon syrup, I grow yacon plants and have access to the delicious yacon roots.  I do not know how to make the syrup and I do not intend to find out, I certainly have no intention of ever buying yacon syrup!  Nowhere on the internet seems to mention anything about yacon root (which I grow) being used in water kefir.  There is no one saying that they have tried this and failed or succeeded, someone needs to try this and let people know if it works or not.  That is why I am writing this post.
Yacon kefir - all the bubbles are gone because I carried the jar outside to take a picture

This is almost certainly not the best way to do this, but it is my first attempt so I will write what I did, and what I think should be done differently to make it better.  At some point in the future I may write another post and say what I changed and how it worked (or did not work).


Yacon Water Kefir

Ingredients:
1 small peeled yacon root (about the size of my thumb, perhaps a bit larger)
1 small peeled and grated yacon root (similar size to above)
1/2 cup water kefir grains
4 cups water

Method
1) add water kefir grains and water to a jar
2) squeeze the liquid out of the grated yacon root.  I put a strainer above the jar and squeezed above this so that the liquid would go in but not the solids.  Discard the squeezed and grated yacon
3) add the peeled yacon to the jar of liquid
4) wait 2 days for the kefir to do its thing.  I do not put a lid on the jar but you need some way to prevent insects and dust from entering
5) remove the yacon root, remove the kefir grains, drink the liquid.  Pretty simple


Even before the 2 days were up I noticed a few things.  Firstly, grated yacon is delicious!  I think it would go well in a salad being grated like this.  Secondly the kefir was bubbling a bit, this tends to indicate that the grains are working well.  If the jar had a lid we may have had issues with the pressure.


What does it taste like, Would I do this again

It tastes alright, but nothing to write home about.  It is similar to how water kefir tastes when it is made on sugar rather than adding any kind of fruit.  The water tastes like it is bubbling, even when it is not, other than that it does not have a strong taste.  I could barely taste the yacon, if I did not know that yacon was in there I would not have guessed it.  Kind of like soda water but without being bitter.

I don't think I will do this again, or if I do I will change things around and perhaps add some limes.  I love how water kefir normally turns out and found this yacon kefir to be less than exciting.  I also prefer to eat yacon normally rather than to eat it after it has been kefired.  The water kefir grains did not multiply as much as I had hoped.  They did multiply a bit, and the grains had been in the refrigerator for a week which generally means that they wont multiply a lot, but I had high hopes.  The water kefir grains have been multiplying slowly lately and I had hoped that the natural sugars in yacon would fix this, apparently we just have to wait for the weather to change.

Interestingly enough, the peeled yacon root also tasted like it was bubbling after it is removed from the completed kefir.  The kids thought that eating the yacon was fun as it did not taste much like yacon, it tasted like it was bubbling.

I also found it interesting that yacon normally discolours reasonably quickly after it has been peeled, but even after two days in the kefir the peeled yacon root looked much the same as when I put it in the jar.


What I would do differently

Yacon kefir tastes ok, but not great.  Adding some kind of fruit or berries or something may have made it much nicer.  Adding some sort of juice or something to the finished yacon kefir certainly makes it taste great.  I don't know, I may try a few different things and then write a post about them.


Where to get yacon and kefir grains

I sell yacon crowns on my for sale page over winter.  I may offer water kefir grains and milk kefir grains for sale, if I do they will be listed on the for sale page too.  Kefir grains sometimes reproduce slowly, other times quite fast, so you may need to contact me to see if they are available.  I also sell a few other organic perennial vegetables and some organic heirloom vegetable seeds.
