Creating your own little symbiotic culture of bacteria and yeast (SCOBY) for kombucha making is as simple as mixing cold, sweet tea with a bottle of unpasteurized kombucha from the store.
Keyword Fermentation, kombucha
Prep Time 2 minutesminutes
Cook Time 10 minutesminutes
Culture 14 daysdays
Equipment
1L jar (wide mouth mason jars are great)
Ingredients
1teabag
2tbspsugar
250mLwater
~473mLunpasteurized kombucha16 oz. See note
Instructions
Mix the sugar with half the water. Bring to a slight simmer and wait for the sugar to dissolve.
Turn off the heat and add the teabag. Let sit for 10 min.
Discard the teabag and pour the tea into a 1 L jar.
Pour in the rest of the water (this is just to help the tea cool faster). Once the tea reaches room temperature, pour in the kombucha.
Cover the jar with something that allows air exchange but prevents anything from falling in, such as a towel, coffee filter, cheesecloth... Secure with a rubber band
Let sit in a dark place for 7-14 days. SCOBY should start forming after 24-48 h. You can take a peek daily and see the SCOBY take form and grow but it's not necessary.
Notes
Unpasteurized kombucha: the volume listed here, 475 mL, is the volume of a small bottle here in Canada. Other similar volumes are most likely perfectly fine. The important part is that the kombucha contains live yeast and bacteria, which they usually do.
