What is a wine screw cap? What is the difference between a cork and a screw cap in wine?

There are too many commercial elements in the screw cap and cork controversy. Whether it's data or blind products, the most important factor is the business interest. Traditionally, the cork has been used for wine closures, but since the successful development of the wine caps by Stelvin, some wine producers have been adopting them.

And as the technology improves, we will see it more and more widely used, and even some famous wineries such as Penfolds have begun to use screw caps for some of their wines. Wine culminates in an ideal environment with slow and regular breathing, and it is normal to choose different types of stoppers depending on the type of wine, and the manufacturer has the right to choose between screw caps and cork.

You can observe the corks of the wines you have drunk, from long stoppers, short stoppers, pure oak stoppers, synthetic stoppers, rubber stoppers, loose stoppers, and screw caps, all of which reflect the wishes of the wine producers and the market positioning and the psychology of consumers to price them.

Not only are the screw-on caps easy to open, but the wines used with them do not smell like cork, and people taste the freshness and purity of the wine. The Mediterranean Wine Cooperative, the main wine cooperative in the south of France, welcomes the use of screwed caps. Juliette Aleon, marketing manager, says that with this cap, people can open a bottle of pure wine anytime, anywhere, without having to bring a troublesome corkscrew.

Wooden stoppers are commonly used in Old World wines, while screws are used in some New World wines. Comparatively, the screw stopper does not have the risk of cork contamination, and does not enter the air to destroy the wine due to poor preservation of the cork, which is the benefit of the screw stopper.

However, a large part of the world believes that the screw stopper is missing the tiny pores of the wooden stopper to make the wine less aged.

The main reason is that the wooden plug will generally look high-end, while the screw plug will be low.

Stoppers are generally used in Old World wines in loose chains, while screws are used in some New World wines.

Comparatively, the screw stopper does not have the risk of cork contamination, and does not enter the air to destroy the wine due to poor preservation of the cork, which is the benefit of the rubber screw stopper.

However, a large part of the world believes that the screw stopper lacks the breathing effect of the tiny pores that lift the cork on the wine, and the wine does not feel aged. The main reason is that the wooden stopper will generally appear high-end, while the screw plug will be lower-grade.

The two upstairs basically said it all. A few more points are added.

1: It is true to prevent the cork from contaminating, but if the bottle is not properly sterilized, it will contaminate and damage the wine.

2: After 10 years, the screw cap will taste better than the cork. I dare not agree with this, and I can only say that the screw cap oxidizes very slowly under the same conditions.

This prolongs the life of many table wines that can only be stored for 3 years, and prevents the aging of ordinary table wines. But for the top wines that can be stored for decades, it is hoped that they will benefit from the slow oxidation process to become better, and if the top wines also choose screw caps, it will prevent the growth of good wines. For example, Penfolds in Australia makes extensive use of screw caps, but its flagships Grange and BIN707 are almost all corks.

It's a screw cap, right? Easy to open, good sealing, prevent cork contamination.

It should be said that wine with screw caps is more suitable for preservation.

Unlike oak corks, wines are stored diagonally or upside down to keep the cork moist and reduce or reduce the amount of air entering the wine. Affects the taste.

The screw cap of the regular manufacturer can prevent the air from entering the wine and affect the taste, and it is very environmentally friendly (the screw cap can be reused).

Also, not all wines are suitable for ageing.

A good bottle of wine depends on various factors such as the place of origin, the year of production (the weather, moisture, and air movement of the year), the irrigation method, and so on.

In this way, a really good wine is suitable for storing and aging, but a wine that has been bottled is not suitable for too long. Generally, after 7-8 years, the wine will precipitate, the color will deteriorate, and the taste will become old and deteriorate.

Hope the above is helpful to you.

A good cork stopper allows the wine to come into proper contact with the air for ageing. Therefore, the wines of the old world that have the potential to age are corked, and ten or twenty years are not a problem. Of course, there is also a bit of ritual when opening the corkage.

However, there are drawbacks to this type of cork. In addition to the high cost, mold inside the cork has the potential to contaminate the cork, and if you are not careful, you can ruin a good bottle of wine. To avoid this, countries led by the New World, such as Australia, began to use screw caps.
