Why are most glass beer bottles with green or brown color?


        Summer is the beer carnival season, but have you noticed that although there are brown, blue, and colorless beer bottles in the market, they are mostly green bottles. Why are beer bottles green?

         The choice of this color is basically a market reason, depending on the manufacturer’s market strategy at the time, but there are some traditions.

The history of beer is very long, but the time to put beer in glass bottles is not very long, it is about the mid-19th century. At that time, there were no special beer bottles, and wine bottles were more likely to be used. There may be more green bottles in this period. It is important to know that the color of glass depends on the manufacturing process in that year, and it is not what color you want. Therefore, by the end of the 19th century, when there were special beer bottles, the tradition of green bottles was preserved.

         Until the 1930s, it was discovered that if the beer is packed in a brown bottle, it can make the beer taste better after being left for a while. The reason was discovered later. Light can promote the reaction of alpha acid in beer with sulfide, which makes the taste very bad. Using a brown bottle can prevent this reaction from happening, and the taste is better. Therefore, more beer is used in brown bottles.

         After World War II, there was a period of lack of brown bottles in Europe, so some of the better brands of beer in Europe were repackaged in green bottles. Because these beers are indeed of very good quality, for a time green bottle beer has become synonymous with high-quality wine tasting, so more manufacturers have followed up and used green bottles. At this time, with the popularization of refrigerators and the advancement of sealing technology, the necessity of using brown bottles is basically gone, and it will not bring better quality than bottles of other colors. However, an old brand of beer will not easily change the packaging significantly. At most, adjustments are made to the glass processing technology to make the color more pure and bright or whatever. A major change in the packaging color of a mature brand should be rare. Therefore, Brown and green are still the mainstream of beer packaging.
