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 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 home and small commercial 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 and other narrow-mouth containers don’t allow enough air in 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 bacteria and yeast in a symbiotic solution with sweetened tea. The symbiotic culture creates a matrix 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 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. 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 feeds the SCOBY during fermentation and is converted into vitamins, antioxidants and other beneficial compounds.
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 has cooled to room temperature, pour it into your brewing vessel and add the scoby (store-bought is fine). Cover with a tight-weave cloth, like a bandana or old tee 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 periodically and gently touch the surface. This is normal. The scoby will become smoother and more uniform after each batch of kombucha that you brew. Be sure to keep your jars away from sunlight, as light can cause the kombucha to taste vinegary.
Find a dark place to store your Kombucha where the temperature will not 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 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.
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 liquid in your SCOBY Hotel for your next batch. Continue this process until you have a constant supply. Enjoy!
