Home Brew Kombucha Alcohol Content

Brewing Kombucha in a Brewing System

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

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 easy and requires little space.

Equipment

There are a number of manufacturers who offer systems designed to streamline the process and ensure 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 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 a bottle cleaner brush in conjunction with this product for 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 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 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 usually contains less than 0.5% of alcohol, which is FDA-approved for non-alcoholic labels.

It is important to use only high-quality ingredients when you make your own kombucha. You should choose a non-herbal, unflavored black or green tea with plain white or turbinado sugar to avoid flavors and oils that can compromise the brew. The sweetener feeds the SCOBY during fermentation and is converted into vitamins, antioxidants and other beneficial compounds.

Scobys

A scoby is a collection of bacteria and yeast that form a symbiotic relationship and make kombucha tea. 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 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 your jar somewhere warm and dark. Ferment it for 7-10days. 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. Keep your jars from the sunlight as light can cause kombucha’s taste to be 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 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 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!
