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 your own kombucha can be easy, cheap and convenient. The process is easy and requires little space.
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 – 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 to regulate the temperature of 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 a bottle cleaner brush in conjunction with this product for 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 contains lactic acid bacteria and yeast, which produce the acids and other substances that give kombucha its 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 is a collection of bacteria and yeast that form a symbiotic relationship and make kombucha tea. 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 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. Be sure to keep your jars away from sunlight, as light can cause the kombucha to taste vinegary.
If you want to store your Kombucha in a dark area, make sure the temperature doesn’t fluctuate 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.
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 find mold or fungi in your kombucha, discard it and start again. Use the starter liquid in your SCOBY Hotel for your next batch. Continue this process until you have a constant supply. Enjoy!
