Stelton Collar Wine Stopper

The stopper features a built-in pump. Once you place it in the bottle, you manually press down on the top to remove excess air, which creates a vacuum seal that slows down the oxidation process.

The Collar Wine Stopper is designed to fit standard wine bottles. It may not provide a secure seal on bottles with non-standard neck sizes, such as some sparkling wine or dessert wine bottles.

Like most brass-plated items, the finish can develop a patina over time if not cared for properly. To maintain its luster, ensure you hand wash the stopper gently and dry it immediately after use.

No, this stopper is not dishwasher safe. The high heat and harsh detergents of a dishwasher can damage the brass plating and the internal vacuum mechanism. Hand washing is required to keep it in top condition.

While it depends on the specific wine, using the vacuum seal generally extends the drinkability of an opened bottle by a few days. It is best used for short-term storage rather than long-term preservation.
