Liquor is a popular alcoholic product on the market today. A bottle of high-quality liquor can be stored for a long time.
To achieve long-term storage, the choice of customized bottle lid is very important.
plastic customized bottle lid
In the early and mid-1980s, plastic customized bottle lid became a common packaging method in the liquor industry.
The inner bottle had a plastic sleeve, the outside was rotated with a plastic cap, and a layer of plastic film was sealed on the outer layer.
For wine with plastic lids, it is related to whether the products produced by the manufacturer that provided packaging and lids to the winery at that time were sealed against each other.
For the kind of plastic-covered wine in the 1980s, few wineries now produce it. For plastic-cover packaging, there was a discussion in the circle.
For long-term storage of plastic-covered wine, due to the evaporation of the wine inside the bottle, And the aging of the internal plastic, some organic substances in the plastic will dissolve into the wine body.
The “plasticizer” incident that made a lot of noise a few years ago was also due to the aging of plastic containers and plastic pipes in the production process of liquor, which caused the plasticizer added to the plastic to dissolve in the body of the wine, which in turn made the produced wine “plasticizer”. “Exceeded.
As for the old wine packaged with plastic cover, whether the components in the plastic are dissolved into the wine body still needs to be tested and announced by relevant professional institutions.
Aluminum customized bottle lid
Liquor with aluminum lids became common gradually from the late 1980s, and by the early 1990s, many wineries used aluminum lids to seal liquors.
Compared with the customized bottle lid and plastic caps, the sealing performance and stability of the aluminum caps are indeed better. In the current bottles of good quality, old wines are mostly stored with aluminum caps.
Moreover, the old wine with aluminum lid has such a feature that the wine line with poor sealing is basically not good, and the wine line with good sealing is basically good.
For example, white sand liquor with a metal cover, it is rare to find a good wine line.
Even if it is encountered, it is necessary to identify whether it is suspected of high-pressure liquid injection.
However, the Langquan liquor in the 1990s is well sealed. I have seen many Langquan liquors. wine line.
It is said that Langquan wine used a Japanese bottle cap packaging production line at that time, and the sealing was very good.
Metal screw cap
For liquor with metal screw caps, friends who like to taste wine must pay attention to it.
Repeatedly tightening and opening the customized bottle lid will cause the metal screw mouth and the glass screw mouth of the bottle to rub repeatedly.
Over time, it is easy to wear the outer film of the metal cover , so that many metal fines hang on the mouth of the bottle.
Therefore, for friends in the wine tasting circle, if you choose a customized bottle lid liquor as your tasting sample, it is recommended that you divide this wine into a shared bottle and taste it slowly, because the winery never thought of this bottle When the wine is sold to you, you will repeatedly open the lid for tasting.
cork
For cork customized bottle lid, it is widely used in red wine.
During the storage process of red wine, the wine is often placed horizontally, obliquely or upside down, which makes the wine fully contact the cork, and the cork is elastic and expands after absorbing water, which is better. of sealed wine.
The loose pores inside the cork facilitate the slow exchange of wine with the outside world, and slow oxidation of the wine body to make it mature.
The customized bottle lid white wine is placed straight, which will cause the cork to lack water and make the cork dry and brittle.
Over time, the cork will leak and run out of wine. It is precisely because of this that the current alcoholic drinks in the 1990s are not very good in weight, and many old alcoholic drinks are somewhat runaway.
Because the customized bottle lid white wine is different from the storage method of red wine, the customized bottle lid that has been stored for more than ten years is corroded by the white wine due to the aging of the cork, and many corks have been discolored.
The 1997 Group Drunk and the 2004 Cork Blue and White Lang that I have drank are somewhat woody.
In addition, some friends in the circle also crushed the customized bottle lid and soaked it in the wine.
After a period of time, the wine began to turn yellow with a faint wood aroma.
For the color, flavor and other changes of the cork to the wine body, it is necessary to conduct in-depth research by friends from relevant professional institutions.
Personally, I think that the change of wood to the wine body not only brings about changes in wood aroma and color, but also other Changes that we do not perceive.
rubber stopper
Rubber stoppers were popular in some wineries around 2010.
Some high-end products of wineries will be packaged with rubber stoppers, but until now, large wineries basically do not use this method to seal liquor, mainly because the stopper is too pitted.
It is not because the sealing is not good, but the rubber stopper will show obvious signs of corrosion after a long time of sealing the wine, and the entire rubber stopper will expand.
Many corks are corroded, but the flavor of the wine has not changed. However, it is not known how the corroded rubber cork will affect the wine.
Polymer plug
In the current liquor, metal screw caps, customized bottle lid, polymer plugs, plastic jacket plugs, etc. are commonly used.
For these customized bottle lid and plugs, after the “plasticizer” incident, the industry and wine companies must be There will be strict requirements for the plastic material.
For the plastic inner packaging material in the field of liquor, the use of “plasticizer” is not allowed.
Polymer stoppers are currently popular among many wine companies.
They have good airtightness and environmental protection. However, for this type of stoppers, they have not been popularized in the field of liquor for a long time, and they also need time to be tested.
In general, for customized bottle lid, beer caps, corks and rubber stoppers are not suitable for packaging with liquor, and it is uncertain whether the liquor sealed with beer caps and corks is sealed for a long time.
Yes, but it is easily corroded by liquor, and it is uncertain whether it will dissolve other substances into the liquor.
In contrast, gold screw caps, customized bottle lid, polymer plugs and plastic jacket plugs are all ideal packaging methods for liquor, but for customized bottle lid and plastic plugs, the plastic products must not contain “plasticizer”.
