Wine Saver; it’s a Gas!

Fortified wines, such as ports and sherries, suffer less after being opened than unfortified wines. They’ll keep a week or so in the fridge, but will slowly lose potency, says carswell.

A gizmo like Private Preserve extends the life of open wines. Each time you open the bottle, just inject it with “gas,” and reclose. It also works, they say, with spirits and even fine oil and vinegar.
