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 the immune system and reduce depression symptoms.
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 easy and requires little space.
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: 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 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. A heating mat is also useful in winter for warming up kombucha.
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 with a bottle brush to get the best results.
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 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 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 to use only high-quality ingredients when you make your own kombucha. 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.
A scoby is a collection of bacteria and yeast that form a symbiotic relationship and make kombucha tea. You can purchase a starter online, get a scoby by asking friends or family who make kombucha to give it to you or attend a workshop that will provide the starter.
Pour the tea into your brewing vessel once it has reached room temperature. Add the scoby. 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 the jar in a dark, warm place for 7-10 day. Check the jar occasionally and gently touch the surface of the scoby. This is normal. The scoby will become smoother and more uniform after each batch of kombucha that 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 decide to store your tea in a cabinet, keep a jar with starter tea nearby just in case you need to re-start the batch.
Always handle a SCOBY using clean hands, and use sterile tools. 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 in your SCOBY Hotel for your next batch. Continue this process until you have a constant supply. Enjoy!
