[Wine Knowledge You’re Too Afraid to Ask 05] What’s the appeal of screw caps?

Screw caps have become common in recent years. They are easy to open and help preserve the freshness of the wine, so they are now used on many wines. Here we will introduce the appeal of screw caps.

What is a screw cap?

A screw cap is a metal cap with a spiral thread that tightly seals the mouth of a wine bottle. It can be opened easily by simply turning the cap, and it prevents oxygen from entering, so the wine stays fresh for a long time.

The difference between cork and screw cap

Cork stoppers are natural materials that allow a small amount of oxygen to pass through, accelerating the aging of wine, but there is a risk of quality variation and moldy odor called "cork taint." On the other hand, screw caps are highly airtight and allow almost no oxygen to pass through, making it easier to maintain the freshness of wine. In addition, they are convenient and popular because they are easy to reseal and have stable quality control.

Eco-friendly wine caps

Screw caps are less harmful to the environment than cork stoppers and are made from recyclable materials (aluminium and steel). Cork production uses forest resources, making screw caps a sustainable choice from a forest conservation perspective. In addition, the production process requires less energy, minimizing the impact on the environment.

Stable quality maintenance

Screw caps provide excellent sealing and prevent oxygen from entering, so they can stabilize the quality of wine for a long period of time. This reduces quality deterioration after opening, allowing you to enjoy the fresh fruit flavor and aroma for a long time. In addition, it is easier to consistently control the quality during the manufacturing process, and there is less risk of defective products like those seen with cork stoppers, so the quality of the wine can be maintained consistently.

Wines suitable for screw caps

Screw caps are ideal for wines that emphasize freshness. They are particularly suitable for white wines, rosé wines, and light red wines, allowing you to enjoy the fruity aroma and vivid flavor for a long time after opening. They are also used for champagne and sparkling wines, allowing you to enjoy them easily. They are suitable for wines that are intended for early consumption rather than aging, providing stable quality control and ease of opening. They are now also used for high-quality wines, allowing you to enjoy them in a variety of situations.
