Can You Cold Brew Kombucha

Brewing Kombucha in a Brewing System

Kombucha is a healthy beverage that contains beneficial bacteria and yeast. It also contains vitamins and minerals. It can help boost the immune system and reduce depression symptoms.

The FDA says kombucha poses no health risks when it’s brewed correctly. Brewing your own kombucha is easy, inexpensive 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: 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. 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 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 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 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 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 feeds the SCOBY during fermentation and is converted into vitamins, antioxidants and other beneficial compounds.

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 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. 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 from the sunlight as light can cause kombucha’s taste to be vinegary.

Stores

If you want to store your Kombucha in a dark area, make sure the temperature doesn’t fluctuate much. A large cabinet or closet is a good choice if you open and close it often enough. 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!
