Different production processes After the beer is fermented, before filling, it is necessary to press the bottle in advance, and pour carbon dioxide or nitrogen into it, mainly to isolate the oxygen in the beer, so that the beer has better stability and is easier to store. Due to the different materials of the bottle body of the glass bottle and the aluminum can, the bottle has good pressure resistance, high pressure, and can be better exhausted
Generally speaking, during the beer filling process, whatever beer is being packaged, it is pressurized with an inert gas such as nitrogen or carbon dioxide. Glass bottles can withstand more pressure than cans, so they can better guarantee the quality of beer. In addition, the properties of glass bottles are relatively stable and do not undergo chemical reactions. The iron and aluminum materials in the can react with the beer and create a metallic taste, so beer in a glass bottle is much better quality than canned beer.
In fact, other than the difference in beer quality and convenience, many of my friends don’t know about it. In fact, the shelf life of bottled beer and canned beer is also very different. Since glass beer has a major problem, which means that bottled beer is relatively poor in protection from light, most bottled beer should have a shorter shelf life than canned beer. However, the brown glass bottles used for some imported beers are better protected from light, but still not as effective as canned ones. Especially in summer, direct sunlight can greatly reduce the shelf life and lifespan of beer.
Comparing bottled beer to canned beer, one of the best things about canned beer is that it’s easier to carry around. Especially for those who like to go out and drink, they must choose canned beer. If it is bottled beer, it is easy to cause fragmentation during transportation, which is particularly inconvenient to carry.
To sum up: when buying beer in life, bottled beer is still the first choice, if you go out and play, you can choose canned beer.
