Ingredients to brew Kombucha:
4 cups of filtered water, then 8 cups of cool filtered water
6 bags of black tea (6 grams of loose tea)
1 cup of sugar
2 cups of “starter tea” from last kombucha brew (if you have it)
1 active Kombucha SCOBY
Stock pot to sterilize bottles
1 gallon glass jar
organic cotton cloth / bag
six swing-top bottles w/ caps – 16.9oz, Amber Glass
glass measuring cup
- Boil four cups of water.
- Add the cup of sugar and dissolve it in a glass receptacle.
- Steep the tea bags in the sugar water for 5-7 minutes.
- Measure out the eight cups of cool water into your gallon glass jar (emptied and cleaned and rinsed).
- Add the four cups of tea to the gallon jar.
- If you have two cups of “starter tea” from the last kombucha brew, add it to the gallon jar.
- Once the gallon jar is room temperature-cool, slip your scoby into the gallon jar.
- Cover the jar with an organic cotton cloth, secure with twine / rubber bands, and set aside in a warm place out of direct sunlight. Ferment for 7 to 10 days.
- After seven days, taste the kombucha daily until the sweet-tart flavor is balanced to your preference.
Ingredients to bottle brewed Kombucha:
orange, ginger, lemon, lime, berries, mint, etc.
Directions for second fermentation/bottling:
- Prepare fresh tea (as directed above) for your next batch.
- Take out the scoby with cleaned hands (rinsed well). Remove the bottom (momma) scoby layer to give away to a friend or toss or save for back-up. Set aside the top (baby) scoby carefully for your next batch in a glass receptacle.
- Set aside two cups of this kombucha homebrew as “starter tea” for your next batch.
- Pour the fermented kombucha into your sterilized (5 minutes boiled) bottles.
- Add sliced flavorings (see above) to bottles — experiment! Leave 1.5 cm. head space in the bottle before capping.
- Prep your next batch: clean the gallon jar after emptied. Combine the 4 cups tea, 8 cups cool water, 1 cup sugar, and 2 cups of “starter tea” in the gallon jar. Slip (newest) scoby carefully into jar.
- Store these bottles at room temperature out of direct sunlight for 2-4 days, and pop the cap open each day to release excess carbonation.
- Refrigerate to stop fermentation. Drink within a month.
I picked up a scoby from a kombucha-brewing friend (Amber) and used regular Lipton tea bags and white sugar (my grandma saves them from her senior community center in Queens). Avoid any teas that contain oils, like earl grey or flavored teas. Avoid touching metal, especially aluminum. Peel off the bottom (oldest) layer every few batches. Can’t wait to try a berries and mint combination, as recommended by a friend!
