These wine preservers can keep an open bottle fresh for weeks—or longer. You might not know that oxidation is the culprit that robs wine of taste once the bottle is open. Each Repour is one-time-use smart stopper that effectively blocks out air, preserving your vintage in a drinkable state.

Chemist (and wine lover) Tom Lutz created Repour to make a bottle’s last glass taste as good as the first. It’s Made in the USA and contains oxygen-absorbing materials that remove oxygen from the bottle and the wine itself, too.

With Repour in place of a standard cork, you can save a full bottle of wine, even if you’re only drinking a glass at a time over days, weeks, or months. Now there’s no pressure to finish a bottle or toss it—it’s patiently waiting for you.
