So, what exactly is kombucha tea?

Kombucha tea, also known as "mushroom tea," is a fermented tea that becomes lightly effervescent naturally and can be made with black or green tea.  Kombucha requires what is often called a "SCOBY" which is short for Symbiotic Colony of Bacteria and Yeast.  

The colony of yeast and good bacteria (probiotics) transform the sweetened black or green tea by consuming the sugar and caffeine and growing a thick jelly-like structure that floats on top of the fermenting tea.  The kombucha tea becomes packed with vitamin B, enzymes, probiotics, and antioxidants.

The Kombucha Fermentation Process

Fermenting kombucha is very easy and the ingredients are simple.  After cooling the sweetened black or green tea, add the necessary blend of yeast and good bacteria (for best results use Kombucha Starter Seed™ which guarantees a perfect first batch).  After adding the yeast and good bacteria to the tea, cover the glass container with a tightly woven cloth or filter and let it sit in room-temperature (the optimum temperature for kombucha fermenting is around 70-80 degrees).  The fermentation takes about 7 days and produces a tangy and bubbly drink.
