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 boost your immune system, and reduce depression symptoms.

The FDA states that kombucha is safe to drink when brewed correctly. Brewing kombucha at home is simple, inexpensive, and convenient. The process is simple and requires minimal space.

Equipment

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 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 is specially formulated to remove stubborn residues from jar surfaces and 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 a symbiotic culture of bacteria and yeast with a sweetened tea solution. The symbiotic process creates a matrix of cells 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 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 is typically less than 0.5% in alcohol, which meets FDA requirements for a nonalcoholic label.

It is important to use only high-quality ingredients when you make your own 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.

Scobys

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 has cooled to room temperature, pour it into your brewing vessel and add the scoby (store-bought is fine). Cover the scoby with a tightly-woven cloth, such as an old teeshirt or bandana. This allows airflow but keeps out fruit flies and dust.

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 out of the sun, as it can make kombucha taste vinegary.

Storage

If you want to store your Kombucha in a dark area, make sure the temperature doesn’t fluctuate 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 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!
