Yeast flora is an important material for brewing beer, today Jinan Chinese brewing machinery and equipment will talk to you about the specific requirements for the use of yeast flora when brewing beer with brewery equipment.
The requirements for yeast flora for brewing beer in brewery equipment are as follows:
Selection of yeast strains: Choose yeast strains suitable for brewing beer, generally choose yeast strains that are special for brewing beer, such as saccharomyces cerevisiae (Saccharomyces cerevisiae) and so on.
Purity of yeast: The yeast used to brew beer should have a high purity to guarantee the stability of the fermentation process.
Yeast viability: Choose yeasts with a certain viability to ensure the fermentation rate and beer quality.
Number of yeast: Depending on the brewing process and the type of beer, the right amount of yeast is selected for fermentation.
Yeast metabolites: Yeast produces some metabolites during fermentation, such as ethanol, carbon dioxide, etc., and the type and quantity of these products will also affect the taste and quality of beer.
Stability of yeast: The yeast used to brew beer should have good stability to ensure the smooth progress of the fermentation process and the stability of beer quality.
Yeast tolerance: Yeast used to brew beer should have a certain tolerance, be able to adapt to certain environmental pressures (such as temperature, pH, dissolved oxygen, etc.) and withstand certain nutrient changes.
In conclusion, in the process of beer brewing, the requirements for yeast flora are multifaceted, and factors such as yeast species, purity, viability, quantity, metabolites, stability and tolerance need to be comprehensively considered to ensure a high-quality beer product.
Major opportunities: It is expected that craft beer standards and related regulations will be introduced this year, and the new policy will be in line with the current policies in Europe and the United States
