Brewing Kombucha in a Brewing System
Kombucha is rich in beneficial bacteria, yeast and 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 kombucha at home is simple, inexpensive, and convenient. The process is simple and requires minimal space.
There are several manufacturers that offer systems to streamline the brewing process and ensure consistency. These are ideal for small-scale commercial and home 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 containers with narrow mouths, don’t let enough air into the container during fermentation.
A thermometer. Often overlooked, but essential to regulate the temperature of 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: 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 produced by mixing a symbiotic bacteria and yeast culture with a sweetened solution of tea. The symbiotic process creates a matrix of cells 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 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 to use only high-quality ingredients when you make your own 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.
A scoby consists of bacteria and yeast which form a symbiotic relation and produce kombucha. You can buy a scoby online, or get one from friends and relatives who make kombucha.
Once the tea has cooled to room temperature, pour it into your brewing vessel and add the scoby (store-bought is 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 out fruit flies and dust.
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. 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.
Find a dark place to store your Kombucha where the temperature will not fluctuate too much. A large cabinet or closet is a good choice if you open and close it often enough. 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.
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 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!
