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 easy and requires little space.
Equipment
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 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. 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: Specially formulated for removing stubborn residues which can form on jars surfaces and in narrow necks. Use a bottle cleaner brush in conjunction with this product for best results.
Ingredients
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 process creates a matrix of cells called a biofilm. The biofilm contains lactic-acid bacteria and yeast that produce acids and other substances which give kombucha it’s distinctive flavor and nutritional value.
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 typically contains less than 0.5% alcohol, which meets FDA regulations for a non-alcoholic 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.
Scobys
A scoby consists of bacteria and yeast which form a symbiotic relation and produce kombucha. 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.
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 airflow but keeps out fruit flies and dust.
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. It is normal for the scoby to feel nubbly or rough. With each batch you brew, it will become smoother. Be sure to keep your jars away from sunlight, as light can cause the kombucha to taste vinegary.
Storage
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 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.
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 find mold or fungi in your kombucha, discard it and start again. 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!
