Kombucha is a low calorie naturally carbonated beverage that has been fermented using microorganisms. The "culture" looks somewhat like a mushroom top, and as such is often called a mushroom. It is also sometimes called SCOBY, for "Symbiotic Colony of Bacteria and Yeast", and is clinically known as a fungus.
Kombucha contains many different cultures along with several organic acids, active enzymes, amino acids, and polyphenols. Depending on the source of the culture the following components may also be present : Acetic acid, which provides much anti-microbial activity; butyric acid, gluconic acid, glucuronic acid, lactic acid, malic acid, oxalic acid, usnic acid, as well as some B-vitamins. If your a home brewer there is no way to know the amounts of the components unless a sample is sent to a lab.
These microorganisms feed on a mixture of sugar and tea. Because tea is used, Kombucha is a popular drink because of its health benefits. During the Qin Dynasty (250 BC), the Chinese called it the "Immortal Health Elixir," partially because they felt Kombucha aided in digestion, allowing the body to focus on healing.
In addition to the health benefits, drinking Kombucha can be surprisingly invigorating and intoxicating. Alcohol amounts vary from 0.5% to 1.5%, depending on anaerobic brewing time and proportions of microbe. This low level of alcohol and caffeine does not explain the feeling of well being, relaxation, and euphoria that some people experience. One possible cause of these effects is the psychoactive amino acid L-theanine, which is naturally present in tea. Stimulation of the circulatory and immune systems, and associated glandular releases, may also account for some of these effects. It is common to drink three glasses a day for maximized effects. One glass on an empty stomach in the morning, the second glass after a meal in the course of the day, and the last glass before bed.
