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 says kombucha poses no health risks when it’s brewed correctly. Brewing kombucha at home is simple, inexpensive, and convenient. The process requires minimal space and is simple.

Equipment

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

Large glass container: Look for one or two-gallon containers that are solid without a spigot, especially ones with a wide neck (smaller surface area allows more oxygen). Mason jars, and other containers with narrow mouths, don’t let enough air into the container during fermentation.

A thermometer. Often overlooked, but essential to regulate the temperature of fermentation. In winter, a heating pad can be used to warm up kombucha if it is too cold.

Long, flexible brush for bottle cleaning: Ideal for cleaning bottles in tight corners. 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 is a tea that has been fermented and touted as having health benefits. It is produced by mixing a symbiotic bacteria and yeast culture with a sweetened solution of tea. The symbiotic culture creates a matrix called a biofilm. The biofilm contains lactic-acid bacteria and yeast that produce acids and other substances which give kombucha it’s distinctive flavor and nutritional value.

The symbiotic process also breaks down sugar into carbon dioxide and small amounts of alcohol, which is why kombucha is sometimes referred to as “the champagne of health.” Commercial kombucha usually contains less than 0.5% of alcohol, which is FDA-approved for non-alcoholic labels.

When you brew your own kombucha, it is important to use high quality ingredients. Choose a black or green tea that is not herbal and unflavored, with white or turbinado plain sugar to avoid oils or flavors that could compromise the brew. The sweetener feeds the SCOBY during fermentation and is converted into vitamins, antioxidants and other beneficial compounds.

Scobys

A scoby is made up of bacteria and fungi that form a symbiotic partnership and make kombucha. 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 is at room temperature, add the scoby to your brewing vessel (store-bought scobys are 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 fruit flies out and dust out.

Place your jar somewhere warm and dark. Ferment it for 7-10days. The scoby will become smoother and more uniform with each batch of kombucha you brew. If it feels nubbly, rough or patchy, this is normal; the scoby will become smooth and more uniform with each batch of kombucha you brew. Keep your jars out of the sun, as it can make kombucha taste vinegary.

Stores

Find a dark place to store your Kombucha where the temperature will not fluctuate too much. If you have a large closet or cabinet, and you can open/close it frequently to promote airflow, this is a great option. 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’s also important to regularly test your kombucha for harmful bacteria and fungi.

If you do discover mold or fungi, dump your kombucha and scoby and start over. Use the starter liquid in your SCOBY Hotel for your next batch. Continue this process until you have a constant supply. Enjoy!
