It’s a probiotic… it’s a carbonated drink… it’s water kefir!

I started making this as part of my mission to get more probiotics in our diet and it has worked like a charm! The kids love it and ask for it each morning.

Water Kefir Culture

You will need one unusual ingredient for this recipe: water kefir cultures (also called water kefir grains). They aren’t really grains, but are a symbiotic colony of beneficial bacteria that create probiotics and enzymes during the process of breaking down natural sugar.

I got my water kefir grains from this family-owned company. You’ll also need…

Equipment Needed

  • Glass jar (1 quart or half gallon)
  • Wooden spoon for stirring (avoid metal)
  • Towel, cheesecloth, or coffee filter to cover jar
  • Rubber band

Ingredients

Instructions

  • In a half gallon size glass jar, dissolve the sugar in a small amount of hot water. If you plan on making the full half gallon you will need ½ cup of sugar. If you are only filling the jar halfway then you only need ¼ cup of sugar. 
  • When the sugar is dissolved, fill the rest of the jar with cool filtered water and make sure the water is not warm. It must be at room temperature!
  • Add the hydrated water kefir grains.
  • Cover with a towel, cheesecloth, or coffee filter and rubber band to keep out insects and small children.
  • Leave on the counter (preferably at 70-75°F) for 24-48 hours.
  • After 48 hours, strain the water kefir grains through a bamboo or non-metal mesh strainer pouring the liquid into another container. I use a half gallon jar for the first process then strain into two quart size jars.
  • Restart the process by dissolving more sugar in water, adding cool water, and adding the same kefir grains. 
  • To make the water kefir carbonated, pour a couple ounces of fruit juice such as grape, pomegranate, apple, or cherry into the water kefir you just strained. I don’t recommend citrus for this part, as it makes stringy yeast-like things that are not tasty!
  • Once you’ve added the juice, cover the jars tightly with an airtight lid and leave on the counter n additional 1-3 days before drinking or refrigerating.
  • Repeat the process!

Notes

The longer you let your kefir ferment, the more sugar ferments out. So if you’re limiting carbs, I recommend fermenting for the full 48 hours. Don’t leave it longer than that though or it can starve the grains, which need sugar to live!

My Favorite Kefir Variations

  • After the first fermentation, cap the water kefir without adding any juice and leave on the counter. After two days, put in refrigerator and add vanilla extract before drinking — tastes like cream soda!
  • Add lemon juice and drink right after the first fermentation — tastes like lemonade!
  • Do the second fermentation with grape, apple, cherry, or pomegranate for a fizzy fruit flavored soda.
  • Add raisins or prune juice for the second fermentation — tastes like Dr. Pepper.
  • Make a grape or berry flavored second fermentation and mix with iced herbal tea for a carbonated fruity iced tea drink.
  • Add pineapple juice after the first fermentation, but drink right away — don’t allow to ferment or it gets slimy!

    Hi! Just wondering.. Can you reuse kefir grains? Or do you have to get a new batch each time?
    Also.. Can I use cheesecloth to strain, rather than a mesh strainer?
    Thanks!

    Hi Katie

    I would like to try making this, can you please tell me where you get your Rapadura sugar?

  3. Tai B. Avatar

    ok, I’m going to do this. I went to the suggested link to order the water keifer grains, its says 2 tablespoons worth in 4oz of liquid. is this all I need? how much will this produce? my goal is to have about a cup worth a day. thanks! 🙂

    Every time I make kefir I have 3X the amount of grains that I started with. What do I do with all these extra grains? They multiply faster than rabbits!

    1. Lisa Avatar

      me too! I have some hibernating in the fridge, dried, dehydrated, frozen, given away and now don’t know what to do with them.
      Currently 2/3 cup turns into 5/3 cups in one fermentation!

      I need some grains, and would like to know how water kefir tastes. I tried to make some but I did not like and I am not sure I did it right. so I would like to try some from someone who already has experience.

    Is it possible to leave out the sugar in this recipe? Or cut it right down to a bare minimum?

    Also, can I substitute the water for coconut water?

      1. Sunny Avatar

        I start with unsweetened coconut water (cardboard container in the refrigerated groceries) and just add sugar like I’m making water kefir. Turns out great!

    Just wondering at what age would you suggest introducing water kefir to kids?

  7. Holly Avatar

    Do you worry about consuming water kefir while pregnant because of the alcohol content? Is serving it to kids similarly dangerous for the negative effects alcohol has on the nervous system, memory, vision, liver, etc.? I really want to use water kefir to improve my gut health, but I plan to become pregnant. My two-year old son also has digestive problems and I would love for this to help him. But I plan to not use it to avoid the risk of alcohol’s effects and will try to find a non-alcoholic source for probiotics. Are you or readers familiar with any research or experience on water kefir’s alcohol content and its effect on pregnant women or young children? Do you recommend any safer form of probiotics?

    1. Katie - Wellness Mama Avatar

      The alcohol content is so minimal that I’m not worried about it. Also, in most cultures outside of the U.S. children and pregnant women consume small amounts of alcohol, without any negative side effects. It was only after the temperance movement in this country that the practice was deemed “unsafe”.

    How long can you keep the finished water for? Do you need to keep it refrigerated?

    Yay! Since my home would be too cool for cultivating kefir during the winter, I dehydrated my grains.
    Didn’t use a dehydrator; after draining them as well as possible, I laid them out on some clean parchment paper, put that on a few layers of bath towel, and put it all on a heating pad set to lowest temp. I took another piece of parchment paper and put it over the top and carefully folded the edges to seal it.
    Checked it often and it took several days for it to turn into this minuscule layer of “pollen”- like grains. Then I wrapped them up in an envelope of clean parchment paper and put it in a small canning jar with a little bag of DE (diatomaceous earth) for residual moisture absorption.

    Ok. The Yay! is because it worked! I have rehydrated the grains and am now “back in business”. Can’t wait to emit my first home-brewed kefir burb of the summer!

    Thanks, Wellness Mama, thanks to you for getting me started toward wellness in the first place!

    How do you add minerals to the water with egg shells? I have had RO for a while and have just now found out that it needs to have minerals added back into it. Thanks!

  11. Laura Avatar

    Hello – apologies if you’ve answered this somewhere but I’ve recently started drinking Kefir water and am concerned by my sugar intake. I understand that the scobi have to have sugar to eat, live and grow, however when I drink the kefir water it tastes very sweet and I am concerned that I am introducing a lot of sugar into my system. Is this correct or are the grains breaking down the sugar so what I’m ingesting is actually ok / healthy? I don’t drink soft drink or juice so that sugar isn’t really part of my usual diet and I’m subject to yeast infections.

    Many thanks 🙂

      I think it depends on how long you let it ferment: the longer it ferments the less sugar will be present, since the grains will eat it all up, but it will taste “stronger”. Maybe you are just not used to any sugar, and so it tastes sweeter than it really is? I would say maybe that the proof is in whether you develop sugar-related issues. Obviously it would be better to avoid that entirely, but it would be confirmation.

    Hi there! I was wondering if you could use mason jars instead of swing top bottles for the second fermentation (perhaps with a small hole poked in the lid?)? This is my first time to ferment anything, and I want to make sure that I get it all right!
    As a side note, I really appreciate all of the information that you provide through your website!

      You can use mason jars for the 2nd ferments but the jars won’t generate nearly as much carbonation as a swing top bottle would because mason jars aren’t airtight. By this same reasoning poking holes in the top would kinda defeat the whole purpose because you want your water kefir to be as airtight as possible in the 2nd ferment (that way it builds up gas which=fizz).

      A swing top bottle is not your only option though! Just go to your local grocery store and buy a juice that comes in a glass bottle and use that. I actually prefer to use KeVita bottles for my 2nd ferment over one of those swing top bottles because then I can put fruit and ginger in the bottle easily. You can go to KeVita’s website to see where it’s sold in your area (FYI KeVita is the overpriced commercialized version of water kefir; it’s usually about $3 a bottle but that’s cheap if you’re reusing it). I actually looked it up once and apparently lots of people reuse KeVita’s bottles for their water kefir. KeVita is really fizzy so their glass bottles aren’t gonna explode on you provided you use common sense.

    I find my kefir water has a lemony odor to it (I do not put any lemon in). Is this normal?

    Thanks

    Hello,

    I do the all-in-one-ferment; just put the kefir grains in water with sugar (no need to dissolve), a slice or two of lemon with zest (supposed to be anti-fungal and adds some taste) and a handful of dried fruit (any kind can be used) and leave for a day or two. This works really well, tastes great, and it carbonates beautifully without a 2nd ferment. It doesn’t harm the crytals either, as suggested above. Just never cut figs, the little grains are a mess to get out.

    But I too was wondering about the alcohol content? It seems that water kefir has somewhere between 0.2 to 2.5% alcohol after 2 days of fermentation (I’m sensitive to alcohol and I can feel it. Not taste it though). So I’m not sure about giving it to the kids. Is there anything that you think makes it safe though?

    Thanks!!
    Love your site 🙂

    Hello,
    I have quite a few kefir grains I have been using to make milk kefir, is there any way to transition them to water kefir brewing?

    Quick question! My Dr prescribed me a drink called Inner Ecco (coconut water kefir drink that you can get at whole foods/sprouts) 1 tablespoon a day which has 100 Billion probiotics in just that one tablespoon. I would love to make this at home to save money but how can I tell how many probiotics I’ll be getting? Does anyone know? Thanks!

  17. Jamie Avatar

    Thank you so much for this post, I wanted to ask if you know if it would be okay for me to use my water kefir grains in apple juice to ferment and then switch back to a back of sugar water, then maybe coconut water. Is it okay to switch it around like that, or do I need to keep using the same base for one batch of grains.?

  18. Susan Avatar

    Can I use milk kefir grains…I have so many and would like to try water kefir. I had water kefir grains years ago, given to me. I would like to start up again, but only have the milk ones now. Is that possible?
    Thanks for your help.
    Susan

        You can use milk kefir grains in water but you have to do a milk batch with them every month or so, otherwise some of the bacteria will die off.

    I use a few star anise and a stick or two of cinnamon for the second ferment.
