Brewing Kombucha in a Brewing System
Kombucha contains beneficial bacteria and yeast, as well as other 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 can be easy, cheap and convenient. The process requires minimal space and is simple.
Equipment
There are a number of manufacturers who offer systems designed to streamline the process and ensure consistency. These systems are perfect for small commercial and home 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 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 tea that has been fermented and touted as having health benefits. It is made by mixing bacteria and yeast in a symbiotic solution with sweetened tea. The symbiotic culture creates a matrix called a biofilm. The biofilm contains lactic-acid bacteria and yeast that produce acids and other substances which give kombucha it’s distinctive flavor and nutritional value.
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.
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 buy a scoby online, or get one from friends and relatives who make kombucha.
Pour the tea into your brewing vessel once it has reached room temperature. Add the scoby. Cover the scoby with a tightly-woven cloth, such as an old teeshirt or bandana. This allows for airflow while keeping out fruit flies, dust and other contaminants.
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. Keep your jars from the sunlight as light can cause kombucha’s taste to be vinegary.
Storage
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 decide to store your tea in a cabinet, keep a jar with starter tea nearby just in case you need to re-start the 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 discover mold or fungi on your scoby, discard them 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!
