I get a kombucha called “LIVE” and it comes in Cola, Dr. Pepper, Root Beer, and Ginger flavors. My grocery store carries it but Whole Foods also sells it. Very tasty and only 35 calories per bottle.
When I make Kombucha (which is always), I spend about 5 cents for 2 gallons —a relief, since by the (small) bottle it’s usually about $3 at my local Whole Paycheck.
Making it, you can get very creative and explore different flavor combinations:
Apricot, strawberry, blueberry, apple, cherry....
You can also customize the pre and probiotics you add in the 2nd fermentation, which hugely adds to the healthiness.
