1, craft beer: only malt, hops, yeast and water are used for brewing, and no artificial additives are added. Usually, when brewing craft beer, you don't need to consider the cost too much, and most of them will choose the best raw materials for brewing.
2. Ordinary beer: It is also brewed from malt, hops, yeast and water, but in order to pursue the cost, more raw materials such as rice, corn and starch are used instead of malt. The beer wort brewed in this way has a very low concentration and a light taste.
Second, the fermentation process is different
1, craft beer: It is mostly Al process, in which yeast works at the top of fermentation tank and floats above the liquor, and the fermentation temperature is generally controlled at 10-20℃. Fermentation tanks are usually small, and filtration and sterilization are not carried out after fermentation.
2. Ordinary beer: It is mostly Lager process, in which yeast works at the bottom of the fermentation tank and sinks below the liquor, and the fermentation temperature is generally controlled below 10℃. The fermentation tank is large, and after fermentation, filtration and pasteurization are usually used to increase the shelf life (quality guarantee time) of beer.
Third, the fermentation time is different
1, craft beer: Because there is no need to care too much about the cost, fermentation time is often not paid special attention to, and time cost is not considered too much. The fermentation time of the most traditional craft beer can be as long as 2 months, so that the beer is fully fermented, the wort concentration is higher and the flavor is more intense.
2. Ordinary beer: For industrial beer, time is money, so the fermentation time of industrial beer is usually only about 7 days, so the fermentation will not be particularly sufficient, resulting in low wort concentration and lighter flavor.
Extended data:
Craft beer is used to distinguish it from most common industrial beers (Qingdao, Snowflake, Yanjing, Budweiser, Heineken and Carlsberg). This is not directly related to whether the taste is bitter or sweet, whether it is fragrant or sour, and whether the alcohol content is high or not.
Under the background of the increasing saturation of mass beer, the beer market in China shows the trend of rapid development of high-end products, and then the craft beer market is favored by more and more people, and the craft beer has increased significantly.
Beer is brewed by using malt and barley malt as main raw materials, adding hops, liquid gelatinization and saccharification, and then liquid fermentation. Its alcohol content is low, it contains carbon dioxide and is nutritious. It contains a variety of amino acids, vitamins, low-molecular-weight sugars, inorganic salts and various enzymes. These nutrients are easily absorbed and utilized by human body.
Low-molecular-weight sugars and amino acids in beer are easily digested and absorbed, generating a lot of heat energy in the body, so beer is often called "liquid bread". 1l12 bx beer can generate 3 344kJ of heat, which is equivalent to 3~5 eggs or 2 10g bread. If a light manual worker can drink 1L beer a day, he can get one-third of the calories he needs.
