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 has stated that kombucha does not pose any health risks if it is brewed correctly. Brewing kombucha at home is simple, inexpensive, and convenient. The process is simple and requires minimal space.
There are many manufacturers who offer systems that streamline the process and guarantee consistency. These are ideal for home and small commercial 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 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 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 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 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 typically contains less than 0.5% alcohol, which meets FDA regulations for a non-alcoholic label.
It is important that you use high-quality ingredients to brew your kombucha. 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 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.
Once the tea has cooled to room temperature, pour it into your brewing vessel and add the scoby (store-bought is fine). Cover the tea with a cloth of a tight weave, such as a bandana, or an old t-shirt. This allows for airflow while keeping out fruit flies, dust and other contaminants.
Place your jar somewhere warm and dark. Ferment it for 7-10days. The scoby will become smoother and more uniform with each batch of kombucha you brew. 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. 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 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 handle a SCOBY using clean hands, and use sterile tools. It is also important to test your Kombucha regularly for harmful fungi and bacteria.
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!
