Are all kinds of bottle caps really suitable for packaging Chinese liquor?-Part 2

Aluminum caps for liquor began to become popular in the late 1980s, and by the early 1990s, many wineries used aluminum caps to seal liquor. Compared with the previous beer caps and plastic caps, the airtightness and stability of aluminum caps are indeed better. At present, the old wines with good quality bottles are mostly old wines with aluminum caps. Moreover, the old wine with aluminum cover has such a characteristic that the wine line of the poorly sealed wine is basically not good, and the wine line of the sealed wine is basically good. In the 1990s, Japan's bottle cap packaging production line was well sealed.

For liquor with metal screw caps, friends who like to taste wine should pay attention to that repeated tightening and opening of metal screw caps will cause repeated friction between the metal screw and the bottle glass screw. If things go on like this, it is easy to wear the outer film of the metal cover, Makes a lot of metal hang on the mouth of the bottle. Therefore, for drinking friends, if you choose a metal screw cap liquor as your drink, you need to pay special attention.



Some wines use cork to seal white wine, and cork is widely used in red wine. During the storage of red wine, the wine is often placed horizontally, obliquely or upside down, so that the wine can fully contact the cork. It is elastic and expands after absorbing water, which better seals the wine. The loose pores inside the cork facilitate the slow exchange between the wine and the outside world, and the slow oxidation of the wine body makes it mature. The cork liquor is placed straight, which will cause the cork to lack water, make the cork shrink and become brittle, and if things go on like this, it will cause the cork to leak.
