Basic Water Kefir Instructions (see notes for variations)
Light and bubbly, water kefir is a simple and delicious way to balance and strengthen digestion.
Recipe type: Beverage
  • ¼ - ⅓ cup unrefined sugar
  • 1t unsulphured blackstrap molasses (or your chosen source of minerals)
  • 2.5 - 3 cups spring water (leave enough room for your grains and extra space at the top for fermentation gas)
  • ¼ - 1 cup of water kefir grains
  1. Shake up the sugar, molasses, and spring water in a wide-mouth quart-sized mason jar until dissolved. (You don't want your grains getting stuck in a bottleneck on their way out!) Leave an inch or two at the top to allow for the build-up of carbon dioxide.
  2. Add in rinsed grains and close the lid. Some people use cheesecloth with the mason jar band in lieu of the lid, but I've always sealed it. (If you purchased dehydrated grains, follow instructions for rehydration. The directions are similar, but it will take a few rounds to get them going before the water kefir is palatable.)
  3. Leave the grains to ferment at room temperature for 48-72 hours (2-3 days). It's good to taste a spoonful of the drink at 48 hours. If it is too sweet for your liking, let it go another day. It isn't recommended to go beyond 72-96 hours because the grains will weaken.
  4. Strain your finished water kefir and store it in the fridge. I use old juice jars or swing top bottles for this.
  5. Rinse your grains (filtered water is best, but tap is ok) and repeat. Again. And again...
Once you are comfortable with your grains and if they are multiplying well, split some off for experimentation and let the fun begin! There is no limit to what you can create.

Cultured juice sodas: take your finished water kefir (pictured in step 3) and add about ¾-1 cup of juice. I love using a quality, not-from-concentrate grape juice for this. Cherry would be wonderful as well. It is critical to leave even MORE room at the top because it is going to get VERY fizzy! Do not add the grains back in. Leave it to ferment on the counter for another 12-24 hours. (Sometimes I let it sit for only a few hours.) The longer it goes, the less sweet it will be. Refrigerate when you're happy with how it tastes. This is called a second fermentation.

You can also add juice straight to your finished water kefir (after straining the grains) without a second ferment. Pop it into the fridge, and enjoy as is. Try the juice of one lemon and a tablespoon of finely grated ginger for a beautiful probiotic lemonade! I've even heard of making cultured mojitos this way, by adding the juice of a lime and muddling some fresh mint.

Dried and/or fresh fruit: It's common to add dried and/or fresh fruit into the batch either before it ferments, or into the finished, strained water kefir. Pineapple, lemon slices and dried unsulphured figs are popular choices. Tepache is a traditional drink of Mexico made with pineapple, brown sugar and cinnamon.

Coconut Water Kefir: follow the instructions using coconut water instead of spring water. You will not need any sugar or molasses. Add the grains right in. The fermentation is MUCH faster. Check it in 6 hours and don't let it go for much longer than 12-15. Some may like the taste, but many will not. It is dry (unsweet) and quite yeasty. But this could be a great option for those avoiding sweeteners.

Cultured Herbal Teas: Steep herbs and/or spices in your spring water and let cool before following the basic recipe. Rosehip and/or hibiscus is delightful!

Dairy Kefir: Water kefir grains will weaken when used in milk (milk grains are best), but if you have extra grains and want to experiment just add the grains to milk with no sugar or molasses. Alternatively, you can add an ounce of finished, strained water kefir directly to milk. Check it after 24 hours or so.

Coconut Milk: This is also a fun thing to experiment with although it will weaken the grains over time. Transfer half a can of coconut milk into a glass container and add 2 tablespoons of grains. Taste it after 24 hours and keep it going if it's not tangy enough for you. The coconut milk can thicken during the process, especially after it is refrigerated and could be used to make cultured coconut whipped cream.
