Brewing Kombucha in a Brewing System
Kombucha contains beneficial bacteria and yeast, as well as other vitamins and minerals. It can boost your 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 simple and requires minimal 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 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. 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 to remove stubborn residues that can form on jar surfaces and in narrow necks. Use in conjunction with a bottle cleaning brush for 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 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 is typically less than 0.5% in alcohol, which meets FDA requirements for a nonalcoholic 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 will feed the SCOBY and be converted into vitamins and antioxidants during fermentation.
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 is at room temperature, add the scoby to your brewing vessel (store-bought scobys are fine). Cover the tea with a cloth of a tight weave, such as a bandana, or an old t-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. 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.
When storing your Kombucha, find a dark spot where the temperature won’t 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’s also important to regularly test your kombucha for harmful bacteria and fungi.
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!
