Kombucha Brew Temperature

Brewing Kombucha in a Brewing System

Kombucha contains beneficial bacteria and yeast, as well as other vitamins and minerals. It can help boost the immune system and reduce depression symptoms.

The FDA has stated that kombucha does not pose any health risks if it is brewed correctly. Brewing kombucha at home is simple, inexpensive, 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 systems are perfect for small 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 or other containers with a narrow mouth do not allow enough oxygen to enter during the fermentation process.

A thermometer is essential for controlling 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: Specially formulated to remove stubborn residues that can form on jar surfaces and in 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 a symbiotic culture of bacteria and yeast with a sweetened tea solution. 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 process also breaks down sugar into carbon dioxide and small amounts of alcohol, which is why kombucha is sometimes referred to as “the champagne of health.” Commercial kombucha is typically less than 0.5% in alcohol, which meets FDA requirements for a nonalcoholic 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 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 with a tight-weave cloth, like a bandana or old tee shirt. 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. 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 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. 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 use sterile equipment and clean hands when handling a SCOBY. It’s important to test your kombucha regularly for harmful bacteria and fungal growth.

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