I am part hippie, being from Oregon, so this is exciting for me.
My kombucha is starting to grow. Took a while, I didn't know anyone with a baby so I tried finding a real chunky Synergy bottle to start with; it worked. It is supposed to aid the liver and fight cancer; personally, like many health products, I'm not totally convinced it does anything but I find the process to be fun and incredibly cheaper than buying it.
I'll have some tips later for making a good brew.
