Comment choisir son matériel de kombucha ?

Kombucha, the ancient beverage tea, has grown to become one of the most popular beverages in the portfolios of leading global beverage companies. Although the exact origin is unknown, the process remains the same. Kombucha benefits include antioxidants, probiotics, antibacterial properties, and more. So you want to make kombucha but don’t know how to choose brewing equipment? In this article, Micet engineers will take you through it.

What is kombucha?

Kombucha is a fermented tea drink. The basic ingredients of kombucha are yeast, sugar, and black tea. Let the mixture sit for a week or more. During this time, bacteria acids, and a small amount of alcohol are formed in the drink. This process is called fermentation.

After fermentation is complete, kombucha is finished and contains vinegar and B vitamins. and many other types of acids, such as amino acids.

What material should my kombucha container be made of?

• Glass: Clear, easy to clean, and safe, it’s the undisputed winner.
• Plastic: Choose only food-grade high-density plastic (HDPE), such as the plastic boilers used in the food industry.
• Stainless Steel: For Professionals! Professional kombucha makers prefer stainless steel tanks (or containers).

What size container to use?

Kombucha can be brewed in any size container, as long as the container is large enough to hold all the kombucha ingredients while maintaining the correct ingredient ratios. When choosing a container size, consider that kombucha has a brewing time of 7 to 30 days. The batch size should be large enough to provide drinkable kombucha as well as the fermented tea needed for the next batch.

kombucha brewery

The hot side of a kombucha brewery (also called a “distillery”) is used to heat water in which sugar-infused black or green tea provides the nutritional elements that SCOBY uses to make kombucha. The sweet tea coming out of the kombucha brewery is cooled to above room temperature and then transferred to the kombucha fermentation tank.

Réservoir de fermentation Kombucha

A commercial kombucha fermenter is where the tea brew undergoes primary fermentation. This process lasts 1 to 3 weeks as the SCOBY does its work, creating the delicious kombucha flavor.

Kombucha Finishing Jar

In commercial kombucha breweries, a third vessel, the kombucha finishing tank (sometimes called a “bright tank”), is used to pass through a combination of flavoring, secondary fermentation, and carbonation before packaging the finished product To complete the kombucha.
