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 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 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 a large, solid, two-gallon glass container without a lid. It should have a wide neck to allow more oxygen in. Mason jars and other narrow-mouth containers don’t allow enough air in during the fermentation process.
A thermometer. Often overlooked, but essential to regulate the temperature of 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: Specially formulated for removing stubborn residues which can form on jars surfaces and in narrow necks. Use a bottle cleaner brush in conjunction with this product for best results.
Ingredients
Kombucha is a tea that has been fermented and touted as having health benefits. It is made by mixing a symbiotic culture of bacteria and yeast with a sweetened tea solution. 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 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. 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 purchase a starter online, get a scoby by asking friends or family who make kombucha to give it to you or attend a workshop that will provide the starter.
Once the tea is at room temperature, add the scoby to your brewing vessel (store-bought scobys are fine). Cover the scoby with a tightly-woven cloth, such as an old teeshirt or bandana. 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. Be sure to keep your jars away from sunlight, as light can cause the kombucha to taste vinegary.
Stores
Find a dark place to store your Kombucha where the temperature will not 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.
Always use sterile equipment and clean hands when handling a SCOBY. It is also important to test your Kombucha regularly for harmful fungi and bacteria.
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!
