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 has stated that kombucha does not pose any health risks if it is brewed correctly. Brewing your own kombucha is easy, inexpensive and convenient. The process is easy and requires little 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: 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 narrow-mouth containers don’t allow enough air in during the fermentation process.
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 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.
Ingredients
Kombucha, a fermented beverage, has been hailed for its 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 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 usually contains less than 0.5% of alcohol, which is FDA-approved for non-alcoholic labels.
It is important to use only high-quality ingredients when you make your own kombucha. Choose a black or green tea that is not herbal and unflavored, with white or turbinado plain sugar to avoid oils or flavors that could 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 buy a scoby online, or get one from friends and relatives who make kombucha.
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 in a warm, dark place and let it ferment for 7-10 days. 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. Be sure to keep your jars away from sunlight, as light can cause the kombucha to taste vinegary.
Storage
If you want to store your Kombucha in a dark area, make sure the temperature doesn’t fluctuate 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 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 use sterile equipment and clean hands when handling a SCOBY. It’s also important to regularly test your kombucha for harmful bacteria and fungi.
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!
