Sounded interesting until I started looking into this. I am trying to get off of Soda. Pretty much stopped drinking. Love wine. I am trying to get my body back to a more neutral pH. I am trying to stay away from acidic drinks (though getting rid of soda is tough)
https://en.wikipedia.org/wiki/Kombucha
Adverse effects associated with kombucha consumption include severe hepatic (liver) and renal (kidney) toxicity as well as metabolic acidosis.[8][9][10] At least one person is known to have died after consuming kombucha, though the drink itself has never been conclusively proved a cause of death.[11][12]
Some adverse health effects may be due to the acidity of the tea, which can cause acidosis, and brewers have been cautioned to avoid over-fermentation.[13][14] Other adverse health effects may be a result of bacterial or fungal contamination during the brewing process.[14] Some studies have found the hepatotoxin usnic acid in kombucha, although it is not known whether the cases of damage to the liver are due to the usnic acid contamination or to some other toxin.[9][15]
