Kombucha Second Ferment

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 is easy, inexpensive 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 home and small commercial 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 or other containers with a narrow mouth do not allow enough oxygen to enter during the fermentation process.

A thermometer: Often overlooked but essential for regulating the temperature during 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: Specially formulated for removing stubborn residues which can form on jars 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 made by mixing bacteria and yeast in a symbiotic solution with sweetened tea. The symbiotic method creates what is called a “biofilm”, a matrix of cells. 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 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 typically contains less than 0.5% alcohol, which meets FDA regulations for a non-alcoholic label.

It is important to use only high-quality ingredients when you make your own 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 has cooled to room temperature, pour it into your brewing vessel and add the scoby (store-bought is fine). Cover with a tight-weave cloth, like a bandana or old tee shirt. 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 occasionally and gently touch the surface of the scoby. 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. Be sure to keep your jars away from sunlight, as light can cause the kombucha to taste vinegary.

Stores

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’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 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!
