Raw materials for brewing beer

As we all know, beer brewing is divided into six systems：mill system, mash system, fermentation system, cooling system, cleaning system, control system.Craft beer brewing requires four raw materials: barley, hops, water and yeast. The quality of these raw materials determines the quality of the beer produced. Understanding the characteristics of these four raw materials and their influence on the process is the prerequisite for processing them, and only in this way can the process control be targeted.

Malt is the main raw material for brewing beer. The composition and quality of malt have a fundamental impact on beer color, aroma, taste, foam, raw material yield and stability.

1. The leaching rate of malt depends on the variety of the original barley, the year and place it was planted, and the protein content. The bottom leaching rate is often due to insufficient protein solubilization. The higher the protein solubility, the higher the leaching rate.

2. The difference in coarseness and fineness indicates the degree of dissolution of the barley cell wall. A small difference in coarse and fine powder means that the cell wall dissolves well, which is beneficial to the filtration and improvement of saccharified wort. A poor coarse and fine powder affects the utilization of raw materials and the filtration rate of wort and beer, as well as the composition of the wort.

3. Although saccharification is the result of the joint action of α and β amylases, the saccharification time can still indirectly indicate the amount of α amylase in the malt. Properly increase low temperature and long-term germination, and increase the concentration of carbon dioxide in the wheat layer in the later period of germination is conducive to the production and accumulation of enzymes, and increasing enzyme activity can shorten the saccharification time.

Water is the most important raw material for beer brewing, and brewing water is called "beer blood". The characteristics of world-famous beers are determined by their respective brewing water. The quality of brewing water not only determines the quality and flavor of the product, but also directly affects the entire brewing process. Therefore, the correct understanding and reasonable treatment of brewing water is of great significance in beer production.

Around the 8th century, German talents used hops as wine. It is precisely because of the presence of hops that the beer has a unique flavor. Hops are the indispensable and most important additive in beer brewing. It has the following functions:

1. It gives beer a refreshing bitterness and pleasant aroma.

2. Increase the antiseptic ability of wort and beer.

3. Increase the bubble retention of beer.

4. The co-boiling of hops and wort can promote protein coagulation, help clarify the wort, and benefit the non-biological stability of beer.

The wort is fermented by brewer's yeast to make beer. Since yeast not only performs alcoholic fermentation, but also the products of its metabolism affect the taste and characteristics of beer, it is very important to understand the structure and composition of yeast, its metabolism, reproduction and growth and its components. Different yeast strains have a series of different characteristics. According to the fermentation method, it is divided into yeasts that are fermented above and those that ferment below. The main function of yeast in beer brewing is to lower blood sugar, produce carbon dioxide and alcohol. Yeasts used in breweries are mainly divided into cultured yeasts and wild yeasts.

1. Cultivated yeast: It is a yeast that is selected from wild yeast, domesticated for a long time, and used repeatedly, and has a normal physiological state and characteristics suitable for beer brewing. 

2. Wild yeast: Yeast that cannot be used for production control is collectively referred to as wild yeast. They are particularly easy to enter the brewery through raw materials. Can produce uncomfortable taste and smell in beer, and cause beer turbidity.
