Cold Brewed Kombucha

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 can be easy, cheap and convenient. The process is easy and requires little space.

Equipment

There are a number of manufacturers who offer systems designed to streamline the process and ensure consistency. These are ideal for home and small commercial 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, and other containers with narrow mouths, don’t let enough air into the container during fermentation.

A thermometer is essential for controlling the temperature during 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: Specially formulated to remove stubborn residues that can form on jar surfaces and in narrow necks. Use a bottle cleaner brush in conjunction with this product for best results.

Ingredients

Kombucha, a fermented beverage, has been hailed for its health benefits. It is made by mixing a symbiotic culture of bacteria and yeast with a sweetened tea solution. The symbiotic culture creates a matrix called a biofilm. The biofilm contains lactic acid bacteria and yeast, which produce the acids and other substances that give kombucha its 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 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 is used to feed the SCOBY, which will then convert it into vitamins and antioxidants.

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 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 the jar in a dark, warm place for 7-10 day. 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. Be sure to keep your jars away from sunlight, as light can cause the kombucha to taste vinegary.

Stores

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 do choose to store your brew in a cupboard, consider keeping a jar of starter tea nearby in case you want to re-start a batch.

Always handle a SCOBY using clean hands, and use sterile tools. It’s important to test your kombucha regularly for harmful bacteria and fungal growth.

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!
