This healthful beverage made from tea, sugar, and a fungal culture mushroom is relatively easy to prepare. For starters, you will need a kombucha culture, sometimes referred to as The Blob. You may obtain a kombucha mushroom culture from a friend. You may also purchase one from a local health food market or order online. It will take approximately six to fifteen days for the fermentation process to complete. But in the end, you will have a delightful pitcher of tangy tea. It does require a bit of prep, but once you get the hang of making it you'll enjoy experimenting with different flavored teas to create your own original concoction that your tastebuds will love.

Here's How:

  1. Wash all utensils with hot sudsy water and rinse well.
  2. Boil three quarts of purified water.
  3. Add 1 cup white sugar to water when a rolling boil is reached. Boil water and sugar mixture for five minutes.
  4. Turn off heat and add 4-5 tea bags of black or green tea.
  5. Steep for 10-15 minutes. Remove tea leaves or bags and let tea cool. (FYI - You may steep the tea longer if you like).
  6. Pour cooled tea into gallon size glass container.
  7. Add your Kombucha culture placing it so that the smooth shiny surface lies up. Add 1 cup of fermented Kombucha Tea from a previous batch (or substitute 1/4 c. distilled vinegar).
  8. Place cheesecloth over the opening of the jar and secure with a rubber band. This keeps dust, mold, spores, and vinegar flies out of the fermenting tea.
  9. Allow to sit undisturbed in a well ventilated and darkened place away from direct sunlight (temp. 65-90 degrees F.) for 6 - 15 days.
  10. To make sure the tea is ready to harvest, pour off a couple of ounces for a taste test.
  11. Taste Test: A taste test on a batch of Kombucha Tea may taste like this: 4-6 Days - Too sweet, not all sugar converted. 7-9 Days - Tastes like sparkling apple cider. 10+ Days - Vinegar taste becoming prominent.
  12. When the tea is brewed to your taste, remove the two cultures.
  13. Gently separate and place the cultures in a glass bowl covered with plastic wrap or a plastic container and refrigerate. They will keep refrigerated for approximately six months, possibly longer.
  14. Pour the fermented tea through a coffee filter and bottle it into glass or food-grade plastic quart bottles.
  15. Date and label the bottled tea and put it in the refrigerator.


  1. 1/4 cup white distilled vinegar can be substituted for the fermented tea starter.
  2. One of the four tea bags can be substituted with an herbal blend for variety.
  3. Sometimes the culture floats on the surface, sometimes it sinks to the bottom of the liquid. Either way is okay. When the culture sinks to the bottom a new culture (baby) will begin to grow on the surface of the tea.
