Water kefir is my new favorite thing to drink. It's so light and naturally bubbly, and can be made into any flavor with the addition of fruit juices. Plus it has the health benefits of living cultured foods. In less than a week and with minimal effort, your kefir grains will transform a small amount of juice and sugar into an amazingly tasty, versatile, and healthful beverage.
There are two stages of fermentation for your kefir, the first ferment and the second ferment. I will describe them both here. When you are given water kefir grains, they will look like this:

Here is how to feed and care for your kefir grains, and produce a delicious tonic in the process:
First of all, they need sugar. Simply mix sugar into warm water until it dissolves. I heat about two cups of water in a pan on the stovetop, just until it's steamy, and then stir in the sugar. There's no need to boil it. More cool water will be added, to bring the total liquid up to about a quart. I loosely measure 1/4 cup of rapidura or sucanat sugar, and stir it to dissolve. This is then poured into a large glass jar with about 1/4 c of water kefir grains. That's it.

Choose the least processed sugar you can find, since the kefir grains benefit from the minerals. If you only have processed sugar, add a dollop of molasses to give back some of the minerals that the kefir needs to thrive.

Let this ferment, undisturbed and at room temperature, for 24-48 hours. Cooler temperatures will slow down fermentation. You don't want the kefir grains to run out of sugar or they will die, so don't let it go too long.
After two days, it's time to strain out the liquid into a bottle or jar, and add some fruit juice. Use whatever flavor you fancy; we've tried fresh apple, grape, elderberry, and orange, and they've all been really good. For the elderberry, I used a small amount of homemade elderberry syrup in place of juice, and it worked great. I tend to use about 1/4 to 1/3 for my ratio of juice to kefir liquid.
