Coravin Model Two: It's the second iteration of the wine preserving system that allows you to pour a glass of wine without ever opening the bottle. A slender hollow needle goes right through the cork to access the wine, and as it's poured, the wine's volume is replaced by an inert gas. This means you can go back to the same bottle weeks, months or even years later and the wine remains the same. A great gift for a single wine lover or for someone whose partner doesn't drink.
