This is how I made my own alcoholic brew from foraged wild blackberries. I use the term "cider" loosely here, since there is no actual apple juice involved. It has great flavor and carbonation, and was a fun and easy home projec
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!
