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 your own kombucha is easy, inexpensive and convenient. The process is simple and requires minimal space.
Equipment
There are a number of manufacturers who offer systems designed to streamline the 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 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 bottle brush: Ideal for cleaning tight corners and nooks. 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 is a fermented tea that has been touted for its health benefits. It is made by mixing bacteria and yeast in a symbiotic solution with sweetened tea. The symbiotic process creates a matrix of cells called a biofilm. 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 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 usually contains less than 0.5% of alcohol, which is FDA-approved for non-alcoholic labels.
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 will feed the SCOBY and be converted into vitamins and antioxidants during fermentation.
Scobys
A scoby consists of bacteria and yeast which form a symbiotic relation and produce 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 has cooled to room temperature, pour it into your brewing vessel and add the scoby (store-bought is fine). Cover the scoby with a tightly-woven cloth, such as an old teeshirt or bandana. This allows airflow, but keeps fruit flies out and dust out.
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
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 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 is also important to test your Kombucha regularly for harmful fungi and bacteria.
If you do discover mold or fungi, dump your kombucha and scoby and start over. 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!
