Brewing Kombucha in a Brewing System
Kombucha is rich in beneficial bacteria, yeast and 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 your own kombucha is easy, inexpensive and convenient. The process requires minimal space and is simple.
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: 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. 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 with a bottle brush to get the best results.
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 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 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 typically contains less than 0.5% alcohol, which meets FDA regulations for a non-alcoholic 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.
A scoby consists of bacteria and yeast which form a symbiotic relation and produce kombucha. You can get a scoby from friends or relatives who make kombucha, buy one online or attend a workshop where they will provide you with the starter.
Pour the tea into your brewing vessel once it has reached room temperature. Add the scoby. Cover with a tight-weave cloth, like a bandana or old tee shirt. 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 occasionally and gently touch the surface of the scoby. 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.
When storing your Kombucha, find a dark spot where the temperature won’t 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.
Remember to always handle a SCOBY with clean hands and to use sterilized equipment. It’s also important to regularly test your kombucha for harmful bacteria and fungi.
If you find mold or fungi in your kombucha, discard it and start again. 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!
