Cork Crafts-Cork Wine Stopper
Whether a wine is of good quality or not, you only need to look at the cork to know.
Every bottle of wine has a more magical little thing, that is, the cork.
Although it makes it very laborious to turn on the wine every time, it does not affect its universal use worldwide.
So, how do you tell the quality of red wine through the cork?
View from the type of cork:
If a bottle of wine uses whole wood to make cork, then it should be a high-quality wine, because the cork of whole wood wine has very small pores, and some wines require a certain age to mature in the bottle. This slightly breathable cork helps wine breathe.
If the cork is a combination of broken wood, it is usually ordinary wine, so drink it as soon as possible after you buy it.
Judging from the degree of penetration:
For wine that has been placed for 3-4 years, it is normal when the wine has penetrated into a quarter or even a third of the cork, but if the wine has penetrated into the cork The mouth part of the bottle is missing, which generally means that the cork has lost its sealing effect, and the wine is likely to have deteriorated.
Distinguish from the brand
Many cork stoppers will be branded, and the content of the branding generally indicates the vintage, place of origin, winery and other information of the bottle of wine. These information should be consistent with the wine label.
Distinguish from the cork state
We can use the cork to judge whether the wine is well preserved. Under normal circumstances, the bottom of the cork should be slightly wet, and the other parts are hard and flexible.
If you find that the cork is very hard when you pinch the cork, the cork is too dry, or there are cracks, then you should pay attention to the quality of the wine, because the deterioration of the cork will cause the bottle to fail It is well sealed. If the air cannot be effectively isolated, the wine may undergo accelerated oxidation or other undesirable changes.
Distinguish from the taste and smell the cork. If you smell sulfur, sour, or earthy, it means that the wine has deteriorated. If the cork gives off floral, fruity and other flavors, it means that the wine is of normal quality and you can drink it with confidence.
In general, a good wine goes well with a good cork.
The stopper made of really fast cork generally has better wine quality, while the stopper made of wood residue is cheap. A good oak stopper has no strange odor, and is firm and flexible.
If the cork is too dry or cracked, then you have to be careful about the quality of this wine. Generally speaking, this is also related to the storage of wine. When you buy wine and store it at home, remember to protect it from light, otherwise no matter how good the cork is placed for a long time, it will easily dry out.
