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 boost your immune system, and reduce depression symptoms.
The FDA has stated that kombucha does not pose any health risks if it is brewed correctly. Brewing kombucha at home is simple, 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 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: Often overlooked but essential for regulating the temperature during fermentation. In winter, a heating pad can be used to warm up kombucha if it is too cold.
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.
Ingredients
Kombucha, a fermented beverage, has been hailed for its health benefits. It is made by mixing bacteria and yeast in a symbiotic solution with sweetened tea. The symbiotic method creates what is called a “biofilm”, a matrix of cells. 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. To avoid flavors and oils from compromising the brew, you should use a plain white or turbinado or black tea without any herbs. 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 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 with a tight-weave cloth, like a bandana or old tee shirt. This allows airflow but keeps out fruit flies and dust.
Place the jar in a dark, warm place for 7-10 day. 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. Be sure to keep your jars away from sunlight, as light can cause the kombucha to taste vinegary.
Storage
Find a dark place to store your Kombucha where the temperature will not fluctuate too much. A large cabinet or closet is a good choice if you open and close it often enough. 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 important to test your kombucha regularly for harmful bacteria and fungal growth.
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!
