The vast majority do not know why beer is sold in brown or green bottles, and not in completely transparent ones, as is often the case with other drinks, alcoholic or non-alcoholic.
Why does a traditional beer bottle have such a specific color?
Brewers are already almost 200 years felt that completely transparent colorless bottles they are not the best solution for preserving the quality of the drink in it, despite the hermetic closure.

According to some historical traces, this was noticed at the same time by many breweries around the world, especially German ones.
So, the answer lies in the exposure of beer to UV rays from sunlight, which negatively affect the delicate combination of various chemical components in beer.

But today we know that ultraviolet rays break down the alpha acids from the hops and that as a result there is a chemical reaction with the sulfur present in the beer, which can cause the beer to spoil.
