Why Are Most Beer Bottles Green?
Although beer has a long history, the time it takes to put it in a bottle is not very long, starting around the middle of the 19th century.
At first people even thought that the glass was green. At that time, not only beer bottles, but also ink bottles and even the windows were slightly green. Some relevant professionals said: "this is because the initial craft of manufacturing glass was not so exquisite, it’s difficult to remove ferrous ion type of impurity ions from the raw material, so the finished glass show green."
Later the glass manufacturing process became more advanced, it had the ability to remove these impurities, but the cost is too high to be worthy to do it. And it was found that the green bottle can prolongs the storage time, so at the end of the 19th century, people specially produced green glass bottles for beer, the tradition of using green beer bottles has therefore been preserved.
By the 1930s, people had accidentally discovered that the beer in a brown beer bottle had not changed when it had been placed for a long time." This is because a brown bottle of beer can avoid the effects of light on beer." said he.
A chemical reaction occurs when the beer is exposed to sunlight, producing a bad smell. Using a brown bottle or some dark bottle can absorb most of the light, which can block the reaction. So, more beer was used in brown bottles.
However, after world war II, there was a time when the supply of brown bottles in Europe was in short supply, forcing some of the more famous beer brands to reuse green bottles for beer. Because of the good quality of these brands, green bottle beer has become synonymous with high-quality beer. And then a lot of beer manufacturer followed and using green bottles.
Naturally, as a result of the improvement of production technology, some manufacturers use plastic bottle instead of glass bottles for beer, as a plastic beer bottle maker, we follow the tradition of glass beer bottles and produce the green plastic beer bottles and brown plastic beer bottles.
