Raw materials: In order to reduce the cost of industrial beer, rice, corn, starch, syrup, etc. It is added to the raw materials, while the craft beer is mainly brewed by malt, hops, yeast and water, with more malt and hops, and the brewed wort has a higher concentration.
Brewing process: most industrial beer is Lager process, and the temperature required for fermentation is relatively low, generally below 10℃. After fermentation, in order to extend the shelf life of beer, filtration and pasteurization are needed, so its shelf life is longer, and some can even reach one year or even longer. However, the craft beer is mostly Al technology, and the fermentation temperature is slightly higher, generally at 10-20℃, and the fermentation time can be as long as 2 months. Due to full fermentation, wort has higher concentration and stronger flavor.
Taste: industrial beer tastes light, while craft beer tastes more mellow. Because of the use of different kinds of hops and malt, the taste is more varied.
Wort concentration: The wort concentration of industrial beer is low, and the wort concentration of craft beer is high, which makes craft beer have higher nutritional value.
Shelf life: industrial beer has a long shelf life, which can reach more than one year, while craft beer has a short shelf life, usually within a few months.
In a word, there are obvious differences between industrial beer and craft beer in raw material selection, brewing technology, taste, wort concentration and shelf life.
