You Brew Kombucha Second Fermentation

Brewing Kombucha in a Brewing System

Kombucha is rich in beneficial bacteria, yeast and vitamins and minerals. It can boost your immune system, and reduce depression symptoms.

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

Equipment

There are many manufacturers who offer systems that streamline the process and guarantee 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 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 bottle brush: Ideal for cleaning tight corners and nooks. Brewery wash is specially formulated to remove stubborn residues from jar surfaces and 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 method creates what is called a “biofilm”, a matrix of cells. 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 typically contains less than 0.5% alcohol, which meets FDA regulations for a non-alcoholic label.

It is important that you use high-quality ingredients to brew your 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 made up of bacteria and fungi that form a symbiotic partnership and make kombucha. You can buy a scoby online, or get one from friends and relatives who make kombucha.

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 somewhere warm and dark. Ferment it for 7-10days. Check the jar periodically and gently touch the surface. It is normal for the scoby to feel nubbly or rough. With each batch you brew, it will become smoother. Keep your jars from the sunlight as light can cause kombucha’s taste to be vinegary.

Stores

When storing your Kombucha, find a dark spot where the temperature won’t fluctuate too much. A closet or cabinet is a good option if it’s large enough and you open/close it often enough to promote airflow. 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 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 from your SCOBY Hotel to re-start your next batch and continue this process until you’ve got a constant supply of delicious Kombucha on hand! Enjoy!
