Natural stopper: This is the noble of cork stopper, which is a high-quality cork stopper, which is processed from one or several pieces of natural cork. It is mainly used for still wines and wines with a long storage period. seal. Wines sealed with natural stoppers can be stored for decades without problems, and it is not surprising that the records of more than a hundred years.
Filling stopper: This is a lower status in the cork stopper family. It has the same origin as the natural race, but because of its relatively poor quality, the impurities in the holes on its surface will affect the quality of the wine. Cork powder is used. The mixture of and adhesive is spread evenly on the surface of the cork, filling the defects and breathing holes of the cork. This cork is often used to preserve lower quality wines.
Polymeric stopper: It is a cork stopper made of cork particles and a binder. According to the different processing technology, it can be divided into sheet polymer plug and rod polymer plug.
Plate polymer stopper: It is processed by pressing cork particles into a plate. The physical properties are relatively close to natural stoppers, and the glue content is low. Use more.
Rod polymer stopper: It is processed by pressing cork particles into rods. This kind of stopper has a high content of glue, and the quality is not as good as that of plate polymer stopper, but the production cost is low, and it is more commonly used in developing countries.
The price of polymer stoppers is cheaper than that of natural stoppers. Of course, the quality cannot be compared with natural stoppers. After long-term contact with wine, it will affect the quality of wine or cause leakage. Therefore, it is mostly suitable for wine that is consumed in a short period of time.
Synthetic stopper: It is a composite cork stopper made by a special process. The content of cork particles is greater than 51%. Its performance and use are similar to those of polymer stoppers.
Patch cork stopper: Use polymer or synthetic stopper as the body, stick 1 or 2 natural cork discs on one or both ends of the polymer stopper or synthetic stopper, usually 0+1 stopper, 1+1 stopper, 2+2 stopper Corks, etc., the part that contacts the wine is made of natural materials, which not only have the characteristics of natural corks, but also have better sealing performance than polymeric corks or synthetic corks. Because its grade is higher than that of polymer stoppers and synthetic stoppers, and its cost is lower than that of natural stoppers, it is a better choice for bottle stoppers. It can be used for high-quality wine sealing like natural stoppers.
Sparkling bottle stopper: The part not in contact with the wine is processed by polymerization of 4mm-8mm cork particles, and the part in contact with the wine is processed with two pieces of natural cork with a single thickness of not less than 6mm. It has better sealing effect and is mainly used for the sealing of sparkling wine, semi-sparkling wine and sparkling wine.
Top stopper: also known as T-shaped stopper, it is a cork stopper with a generally small top. The body can be cylindrical or conical. It can be processed from natural cork or polymer cork. The top material can be wood, plastic, ceramic or Metal, etc. This cork is mostly used to seal brandy wine, and some parts of our country also use it to seal yellow wine (old wine) and liquor.
Of course, corks are only classified into these types according to their raw materials and uses. In addition, there are many classification methods. The huge cork family also has 369 and so on, but just like people in life, each has its existence value, whether it is noble or commoner. A clear understanding of corks and corks will surely advance our understanding of wine and enrich our wine culture.
