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!

    I didn’t see this question yet. Can you use the grains over again? If so how do you store them? I’m asking since they were being sold in quantities of 2 tsp.

    I’ve been making it for about a year. The flavors for the second ferment are limitless and so fun to be creative. I use a Pickle-it jar for the first ferment and flip top bottles for the second. The carbonation is over the top (literally) and my ceiling proves it! Cleaning jars and bottles—I poor boiling water over the jar and bottles before I use them to sterilize before each batch. May not be necessary but I like feeling cleaner about it. Let the jars cool before you start, however. I have also made batches using lavender tea (first make big batch of tea and use it for first ferment). It is great before bed. I’ve made it with other teas as well (green, mint, burddock, dandelion). I try to make slightly herbally medicinal batches from time to time. Like I said, it is limitless what you can do. My grains like orgainc sugar and a pinch of himalyan sea salt and bottled spring water in the first ferment, best. I think grains vary…some like molassas…mine hate it. Some things to try for the second ferment—cherry juice and chia seeds (similar to Synergy brand), grapefuit, elderberry (fights virus), ginger, pinapple and coconut. I sweeten with stevia in f2. I am hopeful most of the sugars have been eaten up by the grains by the time it is done so I think it needs a little extra sweetness. It is limitless and so fun.

      Are the same grains used to make Water Keifir and Milk Keifer? I accidentally bought a package for Milk and was wanting to make Water Keifer. I already make my own Kombucha. I even added Chia seeds to some the other day. It was really good. My favorite Kombucha so far is citrus. I can’t wait to experiment with Keifer.

    I finally started using flip-top bottles for my water kefir in it’s second (flavored) fermentation. Since I strain it a bit through several layers of cheesecloth, I was quite surprised to see white things growing in the bottles. It looks like milk kefir. It only showed up in the strawberry and the strawberry/ginger.
    What is this? I have pictures, but don’t know where to post them.

    Thanks,

    I was wondering if I put minced ginger (or lemon, or pineapple, or orange) in the coffee filter and tie it and put it in the bottle with kefir for the second fermentation would it still be flavoured and bubbly?

    I recently made my first batch of water kefir. I did the grape soda variation and it turned out great! My second batch is done its first ferment and I wanted to do the cream soda variation. I misread the instructions though and put the vanilla extract in right after I strained the grains out, instead of waiting until after the second ferment. Is this going to be a problem? Should I chuck it now or wait and see what happens in a couple of days?
    Thanks for your help!

    I have been making water kefir for several months now. It was working well, but now I’m wondering if my storing it in the refrigerator after each batch is causing it to be less carbonated. I store in the refrigerator 1-3 days after each batch covered in water. Would that be causing a lack of carbonation? Also the grains have grown a lot and I wonder if having too many grains could be a source of the problem.

    Hi. I’ve been trying to make kefir and what i cant figure out is that even though my grains seem very healthy and are multiplying like crazy, they don’t seem to eat a lot of sugar and the kefir tastes very very mild with no vinegary taste at all. I’ve made batch after batch for about a month now and when I try to second ferment it wont carbonate, standing on the counter or on the windowsill for the sun. I continually made kefir last summer and didn’t have those problems. It ate the sugar, carbonated a lot. and had a slight vinegar taste. I got the grains from a friend who had them standing in her fridge for months but i don’t think she fed them much. Thank You!

    I have been making and drinking 2nd ferments of kombucha and water kefir. But have been noticing that when I drink the kombucha I tend to get that gnawing feeling in my gut about 2 am or a few hours after drinking in the day. I am not noticing this with the water kefir. I really enjoy the taste and have consumed about 6 oz in the morning and then again about oz of either in the mid day or evening. Any input on why this gnawing feeling? I do not have ulcers and feel good overall besides excessive swelling and arthritic pain in my hands in which I only noticed recently after the drinking of the tea.

    I have found that the kefir grains will also make a great kefir wine. I have had great luck making honey mead as a second ferment.
    I started with a cup of strong ginger bug and added a lb of honey, one lemon, one orange(both sliced), a handful of raisins and enough water to fill a half gallon. I use an airlock to ferment. It takes 3 months to complete, straining after the first month and aging for the additional 2 months to allow the sediment to settle. It taste just like Verde with champagne bubbles. I also have made Dandelion wine and adding grains to the first ferment instead of brewers yeast. I have also used the kefir grains to make fruit and herbal tonics starting with a thicker juice concentrate and adding beneficial herbs. these make a great tonic for taking in small doses before flu season hits. I have had great results with kefir grains.

    I love the theory behind this drink :To your knowledge is it suitable for diabetics?
    My partner is type 2 with stable sugar levels. We’ve been together 6yrs now and my house is a no soft drink and fruit juice household. Water, Milk and Herbal Teas are allowed. Before moving in with me he consumed Litres of soft drink daily, I’d hate to kick start the habit again. Thanks

    If i double the first ferment recipe, in a 2 quart jar, instead of 24-48 hours do i let it sit longer?

    I am so excited to try this out – you made it sound so do-able!! Two newbie questions if anyone knows…..

    ….do the jars have to be boiled/sterilized or can they just be dishwashed jars?

    ….could a silicone spoon work for stirring? I don’t have wooden yet.

    Great video. I thought kefir grains had to go into milk periodically?

    1. Annie Avatar

      There are two very different kinds of kefir grains – one that looks like cheese curds (milk grains) and one that looks kind of like translucent plastic beads (water grains). Some people have used their milk grains to kefir water and non-dairy milks and those have to be periodically “re-charged” in dairy milk. If you have water grains, you never need to feed them any milk.

    Thank you, looking forward to our first batch. Would it be okay to add our diatomaceous earth to our water kefir soda?

    Can you use home-made jam in your second ferment? From what I am understanding the sugar would be perfect for a bubbly kefir, but not sure about the pectin content???? I am rehydrating my grains now and will be ready for my first batch the first of the week….any input will be appreciated. I am also starting my first Kombucha brew, and have drank some that is marketed in a local healthfood store, but have never tasted Kefir. I’m taking a leap of blind faith here! 🙂

    Can we add our D.E. to the water kefir, and how large a container would you start your water kefir with for a family of 8 or 10.

    Thanks!

    Wondering what the shelf life is for kefir water. Should it be stored in the refrigerator or can it be stored in a cool dark place. I’d like to sell it at farmers markets………….also interested in perhaps selling grains……..how feasible would this be?????

    1. Annie Avatar

      Water kefir continues to ferment the longer it’s kept, although refrigeration slows it down considerably. You also have to either store them loosely capped or continue to burp airtight bottles to reduce/eliminate the risk of explosion.

    Hello,

    If the ideal temperature for making water kefir is between 70-75 degrees F, what happens when we drink it where the average body temperature is nearly 100 degrees F? Won’t the probiotics all die off because of the excess heat?

    Thank you for your answer!

    Hello, I’ve tried for a couple months to get some water kefir to be successful. CFH even sent me a second packet of water kefir grains thinking there was possibly an inert packet sent to me the first time. I’ve tried using Trader Joes evap cane juice sugar, adding some sea salt, using spring water from a local public tap, molasses… it’s never done anything. no change in flavor or aroma. Would you have any opinions?? I change it out every two days, sometimes three if I notice it is still just as sweet thinking it just needs time.
    I look forward to brewing kombucha once I’m done nursing my very last ever baby. He just turned one, so it could be any time.. maybe… but water kefir was supposed to hold me over til then!
    Thank You!!

      Kefir needs some time to acclimate to new surroundings. Mine has been going strong for two years with just spring water or well water and brown sugar, Here are some thoughts:

      Be sure to start with a glass jar thoroughly cleaned with vinegar – not soap or detergent.
      Don’t use metal spoons or strainers.
      Give your kefir enough time at first. It may need more than two or three days at a time to acclimate. Just keep tasting and you will know if they still have sugar to eat. Mine took a while to really get going. I just had to be patient.

      Hope you have success!
