According to the beer bottle manufacturers, in Northeast China, beer has an individual name, which is “big green stick”. As the name suggests, it is a green bottle, but why are most beer bottles green? Is it to relieve visual fatigue? Or to forgive people who brag about each other after drinking?
Valiant learned that, in fact, it was originally because it was difficult to remove impurity ions such as ferrous ions in the raw materials when making glass, so the glass at that time was slightly green. Later, because brown beer bottles can absorb most of the light, effectively block ultraviolet light (UV), and prevent beer from producing a skunk smell due to light, brown beer bottles were also replaced.

Do you really know beer? Why are beer bottles green? This was not the case before the 90th century, but for a long time after World War II, brown bottles in Europe were in short supply, and some famous beer brands reused green bottles to hold beer. Immediately afterwards, many beer manufacturers also began to use green bottles one after another.
Later, although the glass manufacturing process was advanced, these impurities could be removed, but the cost was too high, and it was found that green wine bottles could delay the beer’s taste. Therefore, at the end of the 19th century, people specially produced green glass bottles to hold beer. The tradition has thus been preserved. With the popularization of refrigerated appliances and the improvement of sealing technology, some merchants even add ferrous oxide (FeO) and chromium oxide (CrO3) to the glass as coloring agents to make the beer bottles look better in order to make their packaging more vivid. get greener
