I just finished bottling up a batch of kombucha for its second ferment.  I have several flavors here apple, apple-cranberry apple-rhubarb, black cherry, cranberry....I think that's it.  I have been brewing and bottling kombucha for over 1 year and credit it to finally ridding myself of my Diet Coke addiction.  I drank Diet Coke every day, for over 25 years and for several of those years, it was the first thing I drank in the morning.  I craved it sooooo much.  Happily, after about 1 month of not drinking it and instead drinking kombucha, I was able to rid myself of this poison.   I was also able to get my Father off of Diet Coke too, by drinking kombucha.
