I brewed kombucha for several months/years and received absolutely no
benefits from it at all. In fact during this time I developed Type II
diabetes and I attribute some of that to kombucha which contains both
sugar and alcohol. In fact the longer you brew it to lessen the sugar
content, the greater the amount of alcohol it will contain.
I've also practiced the Master Cleanse and found that I had to stop it
because of the maple syrup which is not compatible with Type II.
I was on a Yahoo user's group during my kombucha brewing experiences and they
trashed anyone that tried to use anything other than sugar to brew the tea.
Normally, kombucha contains less than 0.5% alcohol, which classifies it as a
non-alcoholic beverage. Older, more acidic, kombucha might contain 1.0% or 1.5%
alcohol, depending on more anaerobic brewing time and higher proportions of
sugar and yeast
