Many people will have such a question when they buy beer. Why do most beer bottles use dark glass bottles or cans as packaging materials, and basically do not use transparent glass bottles? What is the reason for this?
Briefly talk about why beer bottles use opaque glass wine bottles as packaging materials.
Hops are too sensitive to light. One of the main raw materials of beer is hops, which give beer a special bitter taste when drinking. Because hops are very sensitive to light, there will be peculiar smell under the irradiation of ultraviolet rays, which will affect the taste of beer, and the use of dark glass bottles will effectively reduce the occurrence of this phenomenon. Therefore, most beer bottles are made of opaque glass bottles.
The dry ice in beer evaporates quickly when exposed to light. Beer also contains dry ice. Dry ice is solid carbon dioxide, which will decompose into carbon dioxide when exposed to light and heat. If it is a transparent glass bottle, it will cause the beer bottle to explode, which is likely to cause some accidents. This requires us to choose dark glass bottles when choosing beer packaging.
