I brewed it for awhile. It was pretty easy and you can do endless variations in flavor. Eventually I stopped drinking it regularly enough to keep going and got sick of all the fruit flies it was attracting.
I brewed a few batches myself, but I'm not a fan of vinegar at all, and that's really where the acidity is coming from in Kombucha. I have some water kefir grains lying around (similar beverage to kombucha, but less vinegar from what I understand), but I haven't brewed with it yet.
I've decided that as much as I like the idea of alternative fermented beverages, what I'm really looking for is an adult soda-like beverage. I think I'm just going to make my own soda and leave it on one of my taps in my kegerator. I see myself enjoying that a lot more in the long-term.
