How Does Kombucha Continuous Brew Work

Brewing Kombucha in a Brewing System

Kombucha is rich in beneficial bacteria, yeast and 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 your own kombucha can be easy, cheap and convenient. The process is simple and requires minimal 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: 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 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 is specially formulated to remove stubborn residues from jar surfaces and narrow necks. Use with a bottle brush to get the best results.

Ingredients

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 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 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. 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.

Scobys

A scoby is a collection of bacteria and yeast that form a symbiotic relationship and make kombucha tea. 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.

Pour the tea into your brewing vessel once it has reached room temperature. Add the scoby. 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. 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.

Storage

Find a dark place to store your Kombucha where the temperature will not fluctuate too 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 choose to keep your brew in the cupboard, you may want to keep a starter tea handy in case you wish to re-start another 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 discover mold or fungi on your scoby, discard them 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!
