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 says kombucha poses no health risks when it’s brewed correctly. Brewing your own kombucha can be easy, cheap 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: 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: Often overlooked but essential for regulating the temperature during fermentation. Also, a heating mat can be useful in winter to warm up kombucha that is too cold.
Long, flexible brush for bottle cleaning: Ideal for cleaning bottles in tight corners. Brewery wash is specially formulated to remove stubborn residues from jar surfaces and narrow necks. Use in conjunction with a bottle cleaning brush for 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 process creates a matrix of cells called a biofilm. The biofilm is made up of lactic acid bacteria, yeast and other substances. These acids and substances give kombucha a distinctive flavor and nutritional benefits.
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.
It is important that you use high-quality ingredients to brew your kombucha. 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 is used to feed the SCOBY, which will then convert it into vitamins and antioxidants.
A scoby is a collection of bacteria and yeast that form a symbiotic relationship and make kombucha tea. 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.
Once the tea is at room temperature, add the scoby to your brewing vessel (store-bought scobys are 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 out fruit flies and dust.
Place your jar somewhere warm and dark. Ferment it for 7-10days. Check the jar periodically and gently touch the surface. This is normal. The scoby will become smoother and more uniform after each batch of kombucha that you brew. Keep your jars from the sunlight as light can cause kombucha’s taste to be vinegary.
When storing your Kombucha, find a dark spot where the temperature won’t 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 is also important to test your Kombucha regularly for harmful fungi and bacteria.
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!
