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 kombucha at home is simple, 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 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 narrow-mouth containers don’t allow enough air in during the fermentation process.
A thermometer: Often overlooked but essential for regulating the temperature during fermentation. A heating mat is also useful in winter for warming up kombucha.
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 is a fermented tea that has been touted for its health benefits. It is produced by mixing a symbiotic bacteria and yeast culture with a sweetened solution of tea. The symbiotic method creates what is called a “biofilm”, a matrix of cells. 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 reaction also breaks sugar down into carbon dioxide, and small amounts of ethanol. This is the reason kombucha can be 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. 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 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 get a scoby from friends or relatives who make kombucha, buy one online or attend a workshop where they will provide you with 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 fruit flies out and dust out.
Place your jar somewhere warm and dark. Ferment it for 7-10days. The scoby will become smoother and more uniform with each batch of kombucha you brew. If it feels nubbly, rough or patchy, this is normal; the scoby will become smooth and more uniform with each batch of kombucha you brew. Keep your jars out of the sun, as it can make kombucha 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 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 discover mold or fungi on your scoby, discard them and start over. Use the starter liquid in your SCOBY Hotel for your next batch. Continue this process until you have a constant supply. Enjoy!
