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 says kombucha poses no health risks when it’s brewed correctly. Brewing your own kombucha is easy, inexpensive and convenient. The process requires minimal space and is simple.
There are many manufacturers who offer systems that streamline the process and guarantee consistency. These are ideal for small-scale commercial and home 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 narrow-mouth containers don’t allow enough air in during the fermentation process.
A thermometer is essential for controlling the temperature during fermentation. In winter, a heating pad can be used to warm up kombucha if it is too cold.
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 a bottle cleaner brush in conjunction with this product for best results.
Kombucha is a fermented tea that has been touted 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 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 is typically less than 0.5% in alcohol, which meets FDA requirements for a nonalcoholic label.
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 is used to feed the SCOBY, which will then convert it into vitamins and antioxidants.
A scoby is made up of bacteria and fungi that form a symbiotic partnership and make kombucha. You can get a scoby from friends or relatives who make kombucha, buy one online or attend a workshop where they will provide you with the starter.
Pour the tea into your brewing vessel once it has reached room temperature. Add the scoby. Cover with a tight-weave cloth, like a bandana or old tee shirt. This allows for airflow while keeping out fruit flies, dust and other contaminants.
Place the jar in a dark, warm place for 7-10 day. 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 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 closet or cabinet is a good option if it’s large enough and you open/close it often enough to promote airflow. 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 is also important to test your Kombucha regularly for harmful fungi and bacteria.
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!
