What's the difference between bottled, canned and barreled beer? Which one do you like?

1 bottled beer. Many beers are packed in glass bottles, most of which are green or brown. Green beer bottles are related to tradition:19th century, there were no special beer bottles, but wine bottles were used (most of them were green wine bottles at that time due to the limitation of glass manufacturing technology). Later, with the special beer bottles, the tradition of green bottles was retained, and brown beer bottles were used because they could effectively block the light. Light will promote the reaction between α acid and sulfide in beer, which will make the taste of beer very bad. However, the use of brown beer bottles can prevent this reaction, and the beer will taste better and be more storable. Moreover, glass bottles don't taste like plastic and can withstand greater pressure, which is probably the reason why glass beer bottles are popular. Two cans of beer. Canned beer is mainly portable and suitable for young people. In history, many mass-produced and cheaper beers are canned, so many people think that canned beer is low-end beer. In fact, the cans have good barrier property, are light-tight and oxygen-tight, and can also block ultraviolet rays, which is conducive to maintaining the fresh taste of beer; In addition, the thermal conductivity of cans is better than that of glass bottles, and it is much faster to ice beer. Now more and more craft beer is also using cans, so canned beer is not equal to low-end beer. However, some people think that cans will give beer a metallic taste, which is actually a misunderstanding of canned beer. The inner wall of the tank will be covered with a polymer film to separate the liquid from the aluminum. Polymer membrane contains a very small amount of bisphenol A(BPA), which is harmless to human body. If you pour beer into a glass when drinking canned beer, it will basically have no metallic taste. Barreled beer. Fresh draft beer is usually packed in a metal barrel, and there will be a valve or faucet on the barrel to put the wine into the glass. Draft beer is a kind of beer that achieves certain biological stability through physical sterilization without pasteurization or instantaneous high temperature sterilization. This kind of beer tastes fresher than other beers, but it is generally not storable and should be drunk as soon as possible. Barreled beer is characterized by its large capacity. Most of the beer consumers can buy is 5L barreled beer, which is suitable for large parties. However, a disadvantage of barreled beer is that it can easily go bad if it is not finished in time. It is also troublesome to maintain the wine flow equipment in the bar. If the sanitation work is not done well, the wine will have a strange smell.
