Alcoholic beverages are typically bottled in glass for a number of reasons. One is to preserve the pure taste. Glassware can keep the taste of beverages stored in it neutral, because glass is difficult to chemically react with various beverages, and both plastic and metal may inject various "flavors" into liquids.
Glass can be either single-use or recycled. The glass cups used in bars can be reused after washing, which is not only clean and hygienic, but also can save a lot of money. The sand used to make glass is everywhere in nature, and it can be said that it is inexhaustible. Moreover, glass is not easy to degrade, and it is not a problem to use it for decades. Empty plastic bottles are generally thrown away.
Pasteurization involves spraying boiling water on packaged beer to kill bacteria that may have survived the brewing process. Plastic bottles are easily deformed during pasteurization, while glass bottles are not.
