Brewing Kombucha in a Brewing System
Kombucha is rich in beneficial bacteria, yeast and vitamins and minerals. It can help boost your immune system and reduce symptoms of depression.
The FDA states that kombucha is safe to drink when brewed correctly. Brewing your own kombucha can be easy, cheap and convenient. The process is easy and requires little space.
There are a number of manufacturers who offer systems designed to streamline the 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, and other containers with narrow mouths, don’t let enough air into the container during fermentation.
A thermometer: Often overlooked but essential for regulating the temperature during fermentation. A heating mat is also useful in winter for warming up kombucha.
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, a fermented beverage, has been hailed for its health benefits. It is made by mixing bacteria and yeast in a symbiotic solution with sweetened tea. The symbiotic process creates a matrix of cells 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 fermentation also breaks down sugar to carbon dioxide and small amounts alcohol. This is why kombucha has been 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. Choose a black or green tea that is not herbal and unflavored, with white or turbinado plain sugar to avoid oils or flavors that could compromise the brew. The sweetener is used to feed the SCOBY, which will then convert it into vitamins and antioxidants.
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 is at room temperature, add the scoby to your brewing vessel (store-bought scobys are fine). Cover with a tight-weave cloth, like a bandana or old tee 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. Check the jar occasionally and gently touch the surface of the scoby. It is normal for the scoby to feel nubbly or rough. With each batch you brew, it will become smoother. Keep your jars out of the sun, as it can make kombucha taste vinegary.
Find a dark place to store your Kombucha where the temperature will not fluctuate too much. A large cabinet or closet is a good choice if you open and close it often enough. 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 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!
