How To Ferment Tea

Brewing Kombucha in a Brewing System

Kombucha is a healthy beverage that contains beneficial bacteria and yeast. It also contains vitamins and minerals. It can help boost the immune system and reduce depression symptoms.

The FDA has stated that kombucha does not pose any health risks if it is brewed correctly. Brewing your own kombucha is easy, inexpensive and convenient. The process is simple and requires minimal space.

Equipment

There are several manufacturers that offer systems to streamline the brewing process and ensure consistency. These are ideal for small-scale commercial and home brewing.

Large glass container: Choose a one- or two-gallon container that is solid and without a spigot. Look for ones with a wideneck (a smaller surface area allows for more oxygen). Mason jars or other containers with a narrow mouth do not allow enough oxygen to enter during the fermentation process.

A thermometer is essential for controlling the temperature during fermentation. A heating mat is also useful in winter for warming up kombucha.

Long, flexible bottle cleaning brush: Perfect for scrubbing tight corners and nooks to keep your bottles clean. Brewery wash is specially formulated to remove stubborn residues from jar surfaces and narrow necks. Use in conjunction with a bottle cleaning brush for the best results.

Ingredients

Kombucha, a fermented beverage, has been hailed for its health benefits. It is made by mixing bacteria and yeast in a symbiotic solution with sweetened tea. The symbiotic culture creates a matrix called a biofilm. The biofilm is made up of lactic acid bacteria, yeast and other substances. These acids and substances give kombucha a distinctive flavor and nutritional benefits.

The symbiotic reaction also breaks sugar down into carbon dioxide, and small amounts of ethanol. This is the reason kombucha can be called “the Champagne of Health.” Commercial kombucha typically contains less than 0.5% alcohol, which meets FDA regulations for a non-alcoholic label.

It is important to use only high-quality ingredients when you make your own kombucha. You should choose a non-herbal, unflavored black or green tea with plain white or turbinado sugar to avoid flavors and oils that can compromise the brew. The sweetener will feed the SCOBY and be converted into vitamins and antioxidants during fermentation.

Scobys

A scoby is a collection of bacteria and yeast that form a symbiotic relationship and make kombucha tea. You can purchase a starter online, get a scoby by asking friends or family who make kombucha to give it to you or attend a workshop that will provide the starter.

Once the tea has cooled to room temperature, pour it into your brewing vessel and add the scoby (store-bought is fine). Cover the tea with a cloth of a tight weave, such as a bandana, or an old t-shirt. This allows airflow but keeps out fruit flies and dust.

Place your jar in a warm, dark place and let it ferment for 7-10 days. The scoby will become smoother and more uniform with each batch of kombucha you brew. This is normal. The scoby will become smoother and more uniform after each batch of kombucha that you brew. Keep your jars out of the sun, as it can make kombucha taste vinegary.

Storage

When storing your Kombucha, find a dark spot where the temperature won’t fluctuate too much. A large cabinet or closet is a good choice if you open and close it often enough. If you choose to keep your brew in the cupboard, you may want to keep a starter tea handy in case you wish to re-start another batch.

Always use sterile equipment and clean hands when handling a SCOBY. It is also important to test your Kombucha regularly for harmful fungi and bacteria.

If you find mold or fungi in your kombucha, discard it and start again. Use the starter liquid in your SCOBY Hotel for your next batch. Continue this process until you have a constant supply. Enjoy!
