Reusable and easy to use and clean, FoodSaver Bottle Stoppers will keep partially consumed bottles of wine fresh and great-tasting 5x longer than just re-corking the bottle. Bottle stoppers can also help you keep your favorite gourmet liqueurs, vinegars and oils fresher longer, because they keep out the oxygen that creates "off" flavors. To vacuum package non-carbonated bottled liquids, you can use a FoodSaver Bottle Stopper with the original container. Remember to leave at least one inch of room between contents and bottom of Bottle Stopper, then re-seal bottles after each use.
