A few years ago I tried fermenting veggies. My family weren't big fans of the veggies.  Then I decided to make my own kombucha and then kefir milk.  Which then led to kefir water.  Now today I make just kefir water.  4 out of 6 of my kids LOVE it!!  It's better than soda and so much better for you.  Great way to get probiotics.
