What are the classification of wine bottle stoppers? What do you mean by different kinds?

As long as people who have drunk wine are familiar with corks, small corks play an extremely important role as the patron saint of wine quality. However, most people seem to pay insufficient attention to corks. The cork pulled out of the bottle was put aside coldly, and many people didn't want to look at it again. In fact, if we can look back at those corks that are no longer useful, we will find that they are not a group of ugly ducklings, but there are many differences between them. This is a huge family, with pure blood aristocrats, hybrids, ordinary people and even foreign immigrants. ...

Let's simply distinguish between raw materials and uses. Of course, in fact, the hierarchical difference of this family is much more complicated.

Natural plug

This is a noble cork, the highest quality cork. It is a cork made of one or several natural corks, which is mainly used to seal wine without gas and wine with long storage period. Wine sealed with natural stoppers has been stored for decades without problems, and it is not surprising that it has exceeded the record of 100 years.

filler plug

This is a low-ranking cork in the cork family. It comes from the same source as natural cork, but the impurities in its surface holes will affect the quality of wine because of its relatively poor quality. The mixture of cork powder and adhesive is evenly coated on the surface of cork to fill the defects and air holes of cork. This kind of bottle stopper is usually used to preserve inferior wine.

Polymerization plug

It is made of cork particles and adhesive. According to the different processing technology, it can be divided into plate polymer plug and rod polymer plug. The plate-type polymer bottle stopper is made of cork particles, and its physical properties are close to those of natural bottle stoppers, with low rubber content. It is a good plug, but its production cost is relatively high and it is widely used in developed countries. Rod-shaped polymer plugs are made by pressing cork particles into rods. This kind of plug has high glue content, and its quality is not as good as that of plate polymer plug, but its production cost is low and it is widely used in developing countries.

Polymer plugs are cheaper than natural plugs. Of course, the quality of polymer plugs can't be compared with natural plugs. Long-term contact with wine will affect the quality of wine or cause leakage. Therefore, it is more suitable for drinking wine in a short time.

Synthetic plug

This is a kind of composite cork made by special technology. Cork particle content is more than 565438 0%, and its performance and application are similar to those of polymer plugs.

Patch cork

A polymer plug or a synthetic plug is used as the main body, and/kloc-0 and/or two natural cork discs are pasted on one end or both ends of the polymer plug or the synthetic plug, which usually include 0+1 plug, 1 plug, 2+2 plug, etc. The part in contact with wine is made of natural materials. This kind of bottle stopper not only has the characteristics of natural bottle stopper, but also is superior to polymer bottle stopper or synthetic bottle stopper. Because its grade is higher than that of synthetic polymer bottle stopper and its cost is lower than that of natural bottle stopper, it is a better choice for bottle stopper and can be used to seal high-quality wine like natural bottle stopper.

Bubble bottle stopper

The part that does not contact with wine is made of 4mm-8mm cork particles, and the part that contacts with wine is made of two pieces of natural cork with a single layer thickness of not less than 6 mm, which has good sealing effect and is mainly used for sealing sparkling wine, semi-sparkling wine and sparkling wine.

Top plug

T-plug, also known as T-plug, is a kind of cork with a small top. Its main body can be cylindrical or conical, and it can be made of natural cork or polymeric cork. The top material can be wood, plastic, ceramic or metal. This kind of cork is mostly used to seal brandy, and it is also used to seal yellow wine (old wine) and white wine in some places in China.

Of course, this only divides cork into these categories according to raw materials and uses. In addition, there are many classification methods. The huge Cork family also has three or six grades, but just like people in life, each class has its own value. Whether noble or civilian, a clear understanding of cork and cork will certainly promote our understanding of wine and enrich our wine culture.
