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 your immune system and reduce symptoms of depression.

The FDA states that kombucha is safe to drink when brewed correctly. Brewing your own kombucha is easy, inexpensive and convenient. The process is simple and requires minimal space.

Equipment

There are many manufacturers who offer systems that streamline the process and guarantee consistency. These systems are perfect for small 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. Often overlooked, but essential to regulate the temperature of fermentation. A heating mat is also useful in winter for warming up kombucha.

Long, flexible brush for bottle cleaning: Ideal for cleaning bottles in tight corners. Brewery Wash: Specially formulated for removing stubborn residues which can form on jars surfaces and in narrow necks. Use with a bottle brush to get the best results.

Ingredients

Kombucha is a fermented tea that has been touted for its 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 fermentation also breaks down sugar to carbon dioxide and small amounts alcohol. This is why kombucha has been called “the champagne of health.” Commercial kombucha is typically less than 0.5% in alcohol, which meets FDA requirements for a nonalcoholic label.

When you brew your own kombucha, it is important to use high quality ingredients. 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 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 has cooled to room temperature, pour it into your brewing vessel and add the scoby (store-bought is fine). Cover the scoby with a tightly-woven cloth, such as an old teeshirt or bandana. This allows airflow, but keeps fruit flies out and dust out.

Place your jar in a warm, dark place and let it ferment for 7-10 days. Check the jar periodically and gently touch the surface. 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.

Storage

If you want to store your Kombucha in a dark area, make sure the temperature doesn’t fluctuate much. A large cabinet or closet is a good choice if you open and close it often enough. If you decide to store your tea in a cabinet, keep a jar with starter tea nearby just in case you need to re-start the 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 discover mold or fungi on your scoby, discard them and start over. Use the starter fluid from your SCOBY Hotel and re-start a new batch. Repeat this process until your SCOBY Hotel is always stocked with delicious Kombucha! Enjoy!
