What is a wine bottle screw cap called?

Answered by Arthur Reyes

The bottle screw cap is commonly referred to as a Stelvin Cap. This closure type has gained popularity in recent years and is now widely used in the wine industry. While some may argue that the romance and tradition of the cork cannot be replaced, screw caps have proven to be an excellent alternative for many wines.

One of the advantages of screw caps is their ease of use. Unlike corks, which require a corkscrew or other tool to open, screw caps can be easily twisted off by hand. This convenience makes them particularly popular for everyday drinking wines, as well as wines that are meant to be enjoyed young and fresh.

Another benefit of screw caps is their ability to provide a consistent and reliable seal. Traditional corks can vary in quality, and a small percentage of bottles may be affected by cork taint, which imparts an unpleasant musty odor and taste to the wine. With screw caps, the risk of cork taint is virtually eliminated, ensuring that every bottle tastes as it should.

Screw caps also offer a superior seal in terms of preventing oxidation. Oxygen can slowly seep through a cork over time, which can cause the wine to spoil or age prematurely. Screw caps provide a tight seal, effectively protecting the wine from oxygen and allowing it to retain its freshness and fruit flavors for longer periods.

Furthermore, screw caps have been found to be more reliable in terms of preventing leakage. Corks can sometimes fail to create a tight seal, resulting in wine leaking from the bottle. This is particularly problematic for wines, as the carbonation can be lost. Screw caps eliminate this risk, ensuring that the wine remains securely contained within the bottle.

In my experience as a sommelier, I have come across numerous wines that are sealed with screw caps. These range from young and vibrant white wines to delicate and aromatic reds. The use of screw caps has not only simplified the opening process but has also preserved the quality and integrity of the wines.

It is worth noting that while screw caps are a suitable closure for many wines, they may not be ideal for all types. Wines that require extended aging and development, such as high-end Bordeaux or Burgundy, often benefit from the slow oxygen exchange that occurs through a cork. However, even in these cases, alternative closure types such as synthetic corks or glass stoppers are sometimes used to mitigate the risk of cork taint.

The wine bottle screw cap, commonly known as a Stelvin Cap, is a practical and reliable closure type for many wines. Its ease of use, consistent seal, and ability to prevent oxidation make it a popular choice in the wine industry. While the cork will always hold a special place in the hearts of wine enthusiasts, screw caps have proven to be a valuable alternative that ensures the preservation of the wine's quality and enjoyment.
