A fermentation tank is a specialized container used in the process of fermentation, where microorganisms like yeast or bacteria convert sugars into alcohol, acids, or gases. These tanks are commonly used in the production of beverages such as beer, wine, and kombucha, as well as in food production like yogurt and sauerkraut. They are designed to maintain optimal conditions for fermentation, including temperature and pressure control. Fermentation tanks can vary in size and shape, ranging from small home-brew setups to large industrial vessels. They are typically made of stainless steel to ensure hygiene and durability. The design often includes features like airlocks and temperature gauges to monitor the fermentation process effectively.
