Making water kefir is great for people who enjoy carbonated beverages but would rather have probiotics than artificial flavor and color. These grains are different from milk kefir grains, but they also make an excellent drink. And it's vegan!
I’ve been a little hard on kefir. At first I didn't care for the sour, yeasty tasting milk made from funny little grains. But one taste of pancakes made from the stuff and I was hooked! And kefir is very simple to make from scratch.
