"The difference between craft beer and ordinary beer.

First, craft beer is different from ordinary beer in brewing raw materials.

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 think too much about the cost, and most of them will choose the best raw materials for brewing.

2. Ordinary beer: It is also brewed with malt, hops, yeast and water, but in order to pursue costs, 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: Al process is mostly used, yeast works at the top of fermentation tank and floats above liquor, and the fermentation temperature is generally controlled at 10-20℃. Fermentation tanks are usually small and are not filtered and sterilized after fermentation.

2. Ordinary beer: Lager process is mostly used. The 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 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 particularly valued, and time cost is not considered too much. The fermentation time of the most traditional craft beer can be as long as 2 months, which makes the beer fully fermented, with higher wort concentration and stronger flavor.

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 light 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, China's beer market shows a 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 grown substantially.

Beer is made from malt and barley malt as main raw materials, adding hops, liquid gelatinization and saccharification, and then liquid fermentation. It has low alcohol content, carbon dioxide and rich nutrition. 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 the human body.

Low-molecular-weight sugars and amino acids in beer are easily digested and absorbed, which produces a lot of heat energy in the body, so beer is often called "liquid bread". 1L 12 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.
