There’s at least one drawback to enjoying a bottle of wine: the cork. Getting it out can be a pain, and once it’s out, the wine begins to lose its character because of oxidation. But the Coravin Wine Access Technology lets oenophiles enjoy a favorite vintage while leaving the cork in place. When you’re ready to pour a glass, push the gadget’s thin, hollow needle through the cork. Pressurized argon gas flows into the bottle, forcing wine out without letting oxygen in. When you’re done, withdraw the needle and the cork will reseal itself.
