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 help boost your immune system and reduce symptoms of depression.
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 is simple and requires minimal space.
Equipment
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 narrow-mouth containers don’t allow enough air in during the fermentation process.
A thermometer is essential for controlling 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: 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.
Ingredients
Kombucha, a fermented beverage, has been hailed for its health benefits. It is produced by mixing a symbiotic bacteria and yeast culture with a sweetened solution of tea. The symbiotic culture creates a matrix 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 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. 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 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.
Once the tea is at room temperature, add the scoby to your brewing vessel (store-bought scobys are fine). Cover the tea with a cloth of a tight weave, such as a bandana, or an old t-shirt. 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 occasionally and gently touch the surface of the scoby. 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
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 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 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!
