Gas Wine Preserver

It’s hard to impress a wine snob, but there is one new product that’s winning over even the most discerning oenophiles. Wine preservation spray, like this Private Preserve spray from Wine Enthusiast, keeps wine from oxidizing by putting a layer of inert gas between wine and the air. You just squirt this harmless mixture of nitrogen, carbon dioxide and argon into an opened bottle of wine, put the cork back on, and even an old, delicate wine will last for days.

First seen at a wine snob’s house in Baltimore and now spotted at wine bars like The Bodega in Bushwick, gas wine preserver is available online at Wine Enthusiast or at specialty wine shops like Astor Wines. Each can lasts for about 120 uses. That’s a lot of wine you could be drinking instead of wasting.
