For those who have everything: Coravin 1000

The Coravin 1000 removes wine from a bottle without ever opening it. “No, this is not magic or osmosis at work.” The Coravin’s secret weapon is a long, hollow needle that’s inserted through the cork and allows wine to be poured without exposing the rest of the bottle’s precious contents to oxidation. The needle pumps in argon—a harmless, tasteless gas—creating pressure that forces the wine up the needle and into the waiting glass. Remove the needle, and the cork “naturally heals itself,” preserving the remaining wine indefinitely. “It makes for a neat magic trick too.”
