Brewing Kombucha in a Brewing System
Kombucha contains beneficial bacteria and yeast, as well as other vitamins and minerals. It can boost your 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.
Equipment
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 or other containers with a narrow mouth do not allow enough oxygen to enter 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 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.
Ingredients
Kombucha is a fermented tea that has been touted for its health benefits. It is made by mixing a symbiotic culture of bacteria and yeast with a sweetened tea solution. 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 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 is typically less than 0.5% in alcohol, which meets FDA requirements for a nonalcoholic label.
When you brew your own kombucha, it is important to use high quality ingredients. 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 feeds the SCOBY during fermentation and is converted into vitamins, antioxidants and other beneficial compounds.
Scobys
A scoby is a collection of bacteria and yeast that form a symbiotic relationship and make kombucha tea. You can buy a scoby online, or get one from friends and relatives who make kombucha.
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 fruit flies out and dust out.
Place your jar in a warm, dark place and let it ferment for 7-10 days. 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.
Stores
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.
Always use sterile equipment and clean hands when handling a SCOBY. It’s also important to regularly test your kombucha for harmful bacteria and fungi.
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!
