Great bottles of wine can present owners with a dilemma—when you open them, you have to drink the entire bottle within a couple of days to avoid the leftovers oxidizing. But what if you’re dying to taste that 2007 Silver Oak, but your husband is off with the kids, and it’s only you? Go ahead—with the Coravin system. Just out this fall, Model Two is a sleek device that lets you insert a thin needle through the cork (without pulling it), and pour as much as you want. An inert gas from a small canister shoots in to replace what you’ve poured, preserving the wine from oxygen and keeping it sound for months to come. You can still share with your husband.
