How To Brew One Gallon Of Kombucha

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 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 requires minimal space and is simple.

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 narrow-mouth containers don’t allow enough air in during the fermentation process.

A thermometer: Often overlooked but essential for regulating the temperature during fermentation. In winter, a heating pad can be used to warm up kombucha if it 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 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 culture creates a matrix 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 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.

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 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 scoby with a tightly-woven cloth, such as an old teeshirt or bandana. This allows airflow but keeps out fruit flies and dust.

Place the jar in a dark, warm place for 7-10 day. 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 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 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!
