How To Do Continuous Brew Kombucha

Brewing Kombucha in a Brewing System

Kombucha contains beneficial bacteria and yeast, as well as other 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 simple and requires minimal space.

Equipment

There are several manufacturers that offer systems to streamline the brewing process and ensure consistency. These are ideal for small-scale commercial and home brewing.

Large glass container: Choose a one- or two-gallon container that is solid and without a spigot. Look for ones with a wideneck (a smaller surface area allows for more oxygen). Mason jars and other narrow-mouth containers don’t allow enough air in during the fermentation process.

A thermometer is essential for controlling 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 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.

Ingredients

Kombucha is a fermented tea that has been touted for its health benefits. It is produced by mixing a symbiotic bacteria and yeast culture with a sweetened solution of tea. 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 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 usually contains less than 0.5% of alcohol, which is FDA-approved for non-alcoholic labels.

It is important that you use high-quality ingredients to brew your kombucha. To avoid flavors and oils from compromising the brew, you should use a plain white or turbinado or black tea without any herbs. The sweetener will feed the SCOBY and be converted into vitamins and antioxidants during fermentation.

Scobys

A scoby is made up of bacteria and fungi that form a symbiotic partnership and make 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 fruit flies out and dust out.

Place your jar in a warm, dark place and let it ferment for 7-10 days. The scoby will become smoother and more uniform with each batch of kombucha you brew. This is normal. The scoby will become smoother and more uniform after each batch of kombucha that you brew. Keep your jars from the sunlight as light can cause kombucha’s taste to be vinegary.

Storage

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.

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 do discover mold or fungi, dump your kombucha and scoby 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!
