The fermentation technology should be changed according to the design and structure of the fermentation tank. Under normal circumstances, it is divided into upper fermentation technology and lower fermentation technology according to the different types of yeast used. In our microbrewery equipment, we use the most common fermentation technology. These technologies can be combined in a brewery to produce different types of beer. If you want to know more about microbrewery, you can contact us. Tiantai Brewtech will provide you with a professional turnkey solution. But, we can change certain conditions to shorten or extend this time frame. For example, control the fermentation temperature. It depends on the yeast strain you use and what you are looking for in a beer.

Bottom Fermentation Technology
The bottom fermentation technology is also called the Lagers process. It is a fermentation technology used in industrial beer. After the fermentation is completed, the yeast will settle to the bottom of the fermentation vessel at a fermentation temperature of 5-10°C. The fermentation time is 3-7 days. The beer that is fermented in the lower part has a light taste but is rich in foam.

Top Fermentation Technology
The upper fermentation technology is also known as the Ales process. This process is generally used for the fermentation of craft beer. During the fermentation process, the yeast floats on the fermentation surface with CO2, and the fermentation temperature is 15-20°C. The upper fermentation time is longer, usually 15-30 days. Of course, some craft beers must fermentation for more than 40 days. The beer fermented on the top has a strong taste and a malt aroma.
