Brewing Kombucha in a Brewing System
Kombucha is rich in beneficial bacteria, yeast and 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 kombucha at home is simple, inexpensive, and convenient. The process is simple and requires minimal space.
There are a number of manufacturers who offer systems designed to streamline the 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 or other containers with a narrow mouth do not allow enough oxygen to enter during the fermentation process.
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 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.
Kombucha is a tea that has been fermented and touted as having health benefits. It is made by mixing a symbiotic culture of bacteria and yeast with a sweetened tea solution. The symbiotic process creates a matrix of cells called a biofilm. The biofilm is made up of lactic acid bacteria, yeast and other substances. These acids and substances give kombucha a 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 typically contains less than 0.5% alcohol, which meets FDA regulations for a non-alcoholic label.
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 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 with a tight-weave cloth, like a bandana or old tee 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. It is normal for the scoby to feel nubbly or rough. With each batch you brew, it will become smoother. Keep your jars from the sunlight as light can cause kombucha’s taste to be vinegary.
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 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 fluid from your SCOBY Hotel and re-start a new batch. Repeat this process until your SCOBY Hotel is always stocked with delicious Kombucha! Enjoy!
