I just bought this Komucha, before I had Honest Kombucha, which was good, but a little more expensive and only available at Whole Foods.
This one is more affordable and available at Henry's.
I tried the Original Taste and it was indeed a little sour. All Kombucha Teas have a special taste one has to get used to. Kombucha makes me feel good, I don't have so much appetite anymore, which comes in handy to loose some pounds and it gives me energy.
