Brewing Kombucha in a Brewing System
Kombucha is rich in beneficial bacteria, yeast and vitamins and minerals. It can help boost your immune system and reduce symptoms of depression.
The FDA says kombucha poses no health risks when it’s brewed correctly. Brewing your own kombucha is easy, inexpensive and convenient. The process is simple and requires minimal space.
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 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 bottle cleaning brush: Perfect for scrubbing tight corners and nooks to keep your bottles clean. Brewery wash: Specially formulated to remove stubborn residues that can form on jar surfaces and in 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 made by mixing bacteria and yeast in a symbiotic solution with sweetened tea. The symbiotic method creates what is called a “biofilm”, a matrix of cells. 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. 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 feeds the SCOBY during fermentation and is converted into vitamins, antioxidants and other beneficial compounds.
A scoby is a collection of bacteria and yeast that form a symbiotic relationship and make kombucha tea. 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 the jar in a dark, warm place for 7-10 day. Check the jar occasionally and gently touch the surface of the scoby. 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.
If you want to store your Kombucha in a dark area, make sure the temperature doesn’t fluctuate 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.
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 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!
