True Wine Stopper

The True Wine Stopper is a bottle closure from Esplanda, sold as bar and cellar merchandise rather than as a wine. Its job is to reseal an opened bottle so the wine is not left open to the air overnight. The listing gives no material, size or sealing mechanism. Check the packaging for those details, and don't assume it fits every bottle neck. Stoppers of this kind generally work best on still wines with standard bottle necks, where they slow oxidation enough to keep an opened bottle drinkable for a few days. They do not make a bottle last indefinitely, and they offer no protection against the loss of fruit and freshness that comes with extended exposure to air. Sparkling wine is a different matter. It needs a stopper with a clamp or hinged arms to hold against the pressure of the carbonation, so only use this one on a sparkler if the packaging says it is rated for that. To get the most from any stopper, reseal the bottle soon after pouring and keep it upright in the refrigerator. That includes red wine, because the cold slows the chemical reactions that flatten flavor. Take the red out roughly 30 to 45 minutes before serving so it returns to cool room temperature. Lighter whites and rosés can go straight from the fridge to the glass. A clean, dry neck helps most closures seat properly, so wipe away any drips before pressing it in. A stopper like this also suits bottles you plan to finish within a couple of days, such as a half-drunk weeknight red or a white you poured only one glass from. For anything you hope to keep longer, a vacuum pump or inert-gas system will usually do more than a simple plug.
