Brewing Kombucha in a Brewing System
Kombucha contains beneficial bacteria and yeast, as well as other vitamins and minerals. It can help boost the immune system and reduce depression symptoms.
The FDA states that kombucha is safe to drink when brewed correctly. Brewing your own kombucha can be easy, cheap and convenient. The process is easy and requires little space.
Equipment
There are a number of manufacturers who offer systems designed to streamline the process and ensure consistency. These are ideal for home and small commercial 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 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. 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 is specially formulated to remove stubborn residues from jar surfaces and narrow necks. Use with a bottle brush to get the best results.
Ingredients
Kombucha, a fermented beverage, has been hailed for its 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 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 typically contains less than 0.5% alcohol, which meets FDA regulations for a non-alcoholic label.
When you brew your own kombucha, it is important to use high quality ingredients. You should choose a non-herbal, unflavored black or green tea with plain white or turbinado sugar to avoid flavors and oils that can compromise the brew. The sweetener will feed the SCOBY and be converted into vitamins and antioxidants during fermentation.
Scobys
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 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 out fruit flies and dust.
Place the jar in a dark, warm place for 7-10 day. 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
When storing your Kombucha, find a dark spot where the temperature won’t fluctuate too 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 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 discover mold or fungi on your scoby, discard them 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!
