FoodSaver® bottle stoppers are the best way to keep wine, oils and non- carbonated bottled liquids fresh longer. You will keep their delicate taste fresh by minimizing exposure to air.
FoodSaver® bottle stoppers are not to be used with plastic bottles. Also, do not use with any carbonated or sparkling beverages. Carbonation happens under pressure. A vacuum removes this pressure, releasing the bubbles and causing the carbonated or sparkling beverages to become flat.
