"Coravin delivers the ultimate in wine preservation. Unlike other wine preservers, which only delay the oxidation of your wine, the Coravin Wine Preservation System is designed to pour wine without removing the cork, so wine always tastes like it has just been opened—even years later. The non-coring Coravin Needle gently passes through corks without displacing cork material. Once the Needle is removed, the cork simply expands back to its normal shape. As wine is extracted through the Needle, it is replaced with pure Argon gas, ensuring oxygen never touches the remaining wine, keeping it as fresh as the day it was bottled. Extend the life of wines closed with screw caps for up to three months with Coravin silicone Screw Caps. This specially designed accessory replaces the original screw cap closure and features a silicone liner that can withstand fifty punctures by the Coravin Needle before needing to be replaced.
