What is Kombucha?
Kombucha is a fermented tea beverage with a long history and unique brewing process. It has gained popularity as a health drink in recent years.
History and Origins
Kombucha originated in Northeast China around 220 B.C. The name “kombucha” is believed to come from Dr. Kombu, a Korean physician who brought the fermented tea to Japan as a curative for Emperor Inkyo.
From Asia, kombucha spread to Russia and Eastern Europe. It gained popularity in these regions during the early 20th century.
Kombucha arrived in the United States in the 1990s. Since then, it has become increasingly popular as a health-promoting beverage.
Kombucha Brewing Process
Kombucha is made by fermenting sweetened tea with a symbiotic culture of bacteria and yeast (SCOBY). The SCOBY resembles a rubbery pancake and is often called a “mother” or “mushroom.”
The brewing process typically takes 7-10 days. During this time, the SCOBY consumes most of the sugar, producing various organic acids, vitamins, and enzymes.
The result is a slightly sweet, slightly acidic beverage with a hint of effervescence. Kombucha can be flavored with fruits, herbs, or spices after the initial fermentation.
Home brewing of kombucha has become popular, though it requires careful attention to hygiene and fermentation conditions to ensure safety.
