1. Different brewing materials
(1) Craft beer: brewed with malt, hops, yeast and water without any artificial additives.
(2) Industrial beer: It is also brewed with malt, hops, yeast and water, but in pursuit of cost, more raw materials such as rice, corn and starch are used to replace malt. The resulting beer has a very low wort concentration and a bland taste.
2. Different fermentation processes
(1) Craft beer: mostly ale process, the yeast works at the top of the fermentation tank and floats above the liquor, and the fermentation temperature is generally controlled at 10-20°C. Fermenters are usually small and are not filtered and sterilized after fermentation.
(2) Industrial beer: Most of it is a lager process. The yeast works at the bottom of the fermentation tank and sinks under the liquor. The fermentation temperature is generally controlled below 10°C. The fermentation tank is larger, and filtration and pasteurization are usually used after fermentation to increase the shelf life (shelf life) of the beer.
3. Different fermentation time
(1) Craft beer: Because there is no need to worry too much about the cost, the fermentation time is often not given special attention, and the time cost is not considered too much. The most traditional craft beer can be fermented for up to 2 months, so that the beer is fully fermented, the wort is more concentrated, and the flavor is stronger.
(2) Industrial 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 a low concentration of wort and a lighter flavor.
4, the storage time is different
(1) Craft beer: Most craft beers are not filtered and sterilized, so craft beers are less resistant to preservation. Most craft beers have a short shelf life, some only a few tens of days.
(2) Industrial beer: In the later stage of fermentation, industrial beer is often filtered and pasteurized, and has a long shelf life. The general shelf life of industrial beer is 1-2 years, and some can even reach decades.
