Water Kefir & Probiotic Drinks Recipes

Curated by Evelina Melnikova
Water kefir is the easiest fermented beverage to make and the fastest to produce results. You can go from sugar water to a bubbly, probiotic rich drink in 24 to 48 hours. Compare that to kombucha, which takes 7 to 14 days, and you see why water kefir is where I recommend most beginners start their fermentation journey.
The process is absurdly simple. Dissolve sugar in water, add water kefir grains, cover loosely, and wait 24 to 48 hours at room temperature. Strain out the grains (which you reuse indefinitely), flavor the liquid with fruit juice or fresh fruit, bottle in a sealed container for another 24 hours for carbonation, and refrigerate. The whole cycle from start to fizzy finished drink takes about 3 days.
Water kefir grains are not actually grains in the wheat sense. They are small, translucent, gelatinous clusters of bacteria and yeast that resemble tiny cauliflower florets. You can buy them online or get them from another brewer. They multiply over time, so you will eventually have enough to share. The grains are reusable and essentially immortal as long as you keep feeding them sugar water.
The flavor possibilities are wide open. Grape juice produces something that tastes like sparkling grape soda. Mango juice makes a tropical fizz. Ginger and lemon is like a natural ginger ale. Fresh berries produce a beautiful pink, slightly fruity drink. The base water kefir is mild and slightly sweet on its own, making it a blank canvas for whatever flavor direction you choose.
These 20 recipes cover the basic water kefir process plus a range of flavoring options and a few other probiotic drink recipes that use similar fermentation principles.

Frequently Asked Questions
-
Water kefir is a fermented probiotic drink made by culturing sugar water with water kefir grains (a symbiotic culture of bacteria and yeast). The result is a mildly sweet, slightly tangy, effervescent beverage that can be flavored with fruit juice, fresh fruit, or herbs. It is naturally gluten free, dairy free, and vegan.
-
Water kefir ferments sugar water while milk kefir ferments dairy milk. They use different cultures that are not interchangeable. Water kefir produces a light, fizzy drink similar to soda. Milk kefir produces a thick, tangy, yogurt like beverage. Both are probiotic rich but serve different purposes.
-
Every 24 to 48 hours when kept at room temperature. If you want to take a break from brewing, store the grains in sugar water in the refrigerator. They slow down significantly when cold and only need fresh sugar water once a week. Revive them with a room temperature brew when you are ready to start again.
-
Both contain beneficial bacteria and can support gut health. Water kefir tends to have a wider variety of bacterial strains. Kombucha contains additional organic acids and B vitamins from the tea fermentation. Neither is definitively "better" than the other. Drinking either regularly adds beneficial bacteria to your diet.
-
Raw honey has its own antimicrobial properties that can harm kefir grains over time. Refined white sugar is actually the best food for water kefir grains because it is pure sucrose with nothing that might inhibit the culture. You can use coconut sugar as an occasional alternative.
-
The carbonation happens during the sealed second fermentation. Make sure your bottles are truly airtight. Add a small amount of sugar or fruit juice at bottling to feed the remaining yeast. Ferment at room temperature, not in the fridge. Warmer temperatures produce more carbonation. Give it a full 24 to 48 hours before refrigerating.
