Looks great. I had a five gallon batch perpetually brewing for over 5 years strait. I would drink it everyday. After the third kid came I just couldn't keep up with everything and the kombucha was one of things that I took a break from. But you definitely make me want to get it going again. I used to do all sorts of flavors in second ferment with herbs and fruits. Peach basil jasmine green tea was my fav.
No hot takes on health aspect really. I think it did help somewhat overall with digestion but I didn't think it's a miracle tonic. Mostly I just like it and makes me feel good. A little bit of sugar, a miniscule bit of alcohol, a small amount of caffeine, and lots of yummy fermented goodness.
