Why does craft beer need to be cooled?

The research results of beer experts show that the foam is the richest, fine and long-lasting, with strong aroma and comfortable taste when the beer temperature is 10℃.

However, to maintain this temperature, the beer temperature needs to be adjusted appropriately according to the ambient temperature. For example, when the ambient temperature is 25℃, the beer should be frozen to about 10℃, and when the ambient temperature is 35℃, the beer should be frozen to 6℃. The special beer refrigerator is dedicated to the cooling and cooling function of draft beer.
