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 your own kombucha can be easy, cheap and convenient. The process is simple and requires minimal space.
There are several manufacturers that offer systems to streamline the brewing process and ensure consistency. These systems are perfect for small commercial and home 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 containers with narrow mouths, don’t let enough air into the container during fermentation.
A thermometer. Often overlooked, but essential to regulate the temperature of 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 for removing stubborn residues which can form on jars surfaces and in narrow necks. Use with a bottle brush to get the best results.
Kombucha is a tea that has been fermented and touted as having health benefits. It is made by mixing a symbiotic culture of bacteria and yeast with a sweetened tea solution. The symbiotic method creates what is called a “biofilm”, a matrix of cells. 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 usually contains less than 0.5% of alcohol, which is FDA-approved for non-alcoholic labels.
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 is a collection of bacteria and yeast that form a symbiotic relationship and make kombucha tea. You can purchase a starter online, get a scoby by asking friends or family who make kombucha to give it to you or attend a workshop that will provide 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 airflow, but keeps fruit flies out and dust out.
Place your jar somewhere warm and dark. Ferment it for 7-10days. 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.
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 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 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!
