Water kefir is the vegan cousin of milk kefir and the caffeine-free alternative to kombucha. These live cultures can be used again and again to create refreshing, naturally fizzy probiotic drinks at home.
Easy to make and endlessly versatile, water kefir is a great way to support gut health while creating delicious homemade sodas, fruit ferments, and flavoured drinks.
How does it taste like?
Water kefir has a mildly sweet, slightly tart and refreshing taste similar to a very light, non-alcoholic cider. It is much less acidic and "funky" than kombucha and is naturally caffeine-free.
The exact flavour profile changes and depends on how you ferment it. Because the plain base (1st fermentation with grains) is relatively neutral, it easily takes on whatever flavors you add to it. Many people bottle the plain kefir with fruit, juice, or herbs (2nd fermentation without the grains) for another 1–2 days. This adds natural fruity flavors and creates a fizzy, soda-like sparkle.
Fresh or dried grains — which should I choose?
Both work equally well, so it really comes down to personal preference.
Our dried grains rehydrate quickly and easily — 1 Tbsp of dried grains becomes approximately 3 Tbsp of active hydrated grains within 24 hours and can be used immediately to brew kefir, just like the fresh grains.
Dried grains are especially suitable for:
- Rural deliveries
- Shipping delays
- Gifts
- Long-term storage
They are shelf stable for up to 6 months before needing hydration and feeding.
Fresh grains are already fully hydrated and active, therefore they will need feeding soon after arrival.
Please note:
- Fresh grains are shipped at the beginning of each week
- Dried grains are shipped daily
Why choose our grains?
- Fed exclusively with certified organic ingredients
- Cultured using filtered spring water
- Produced and packed in a certified kitchen
- Grown by experienced kefir brewers with years of hands-on expertise
With proper care, your grains can last indefinitely.
