Beer will be frozen and cracked in an environment exceeding-1.5 degrees Celsius. The alcohol content in beer is relatively high, and the freezing temperature of alcohol is lower than that of water. The freezing point is-1.5 degrees Celsius. When it is lower than-1.5 degrees Celsius, beer will freeze, and the frozen volume will expand. When the expanded volume is greater than the capacity of beer bottles, beer bottles will be frozen and cracked.

Beer is not suitable for frozen storage. Frozen beer is very likely to have the problem of bottle explosion, which is very unsafe. In addition, the taste of frozen beer will deteriorate, and the nutrients in beer will be destroyed, and the protein in wine will be decomposed and dissociated in the low temperature environment.

The taste of beer

Beer has a slightly bitter taste. Beer is made of barley malt, hops and water, and it is a low-alcohol wine full of carbon dioxide by yeast fermentation, that is, a low-alcohol wine made by hydrolyzing and fermenting starch to produce sugar, which is called "liquid bread".

In addition, the whole malt beer brewing follows the pure brewing method in Germany, and all raw materials are malt without adding any auxiliary materials. The cost of beer produced is high, but the malt flavor is outstanding. The first wort beer is fermented directly by using the wort obtained by filtration, without adding the second wort for washing residual sugar. It has the characteristics of mellow taste and clean aftertaste.
