AntiOx Silicone Wine Stopper (set of 6)

This patented system avoids oxidation of wine inside an opened bottle. The silicone based stopper contains an active carbon filter inside. This effectively interrupts oxygen interacting with the wine. This fully functional and useful wine stopper is made in Spain and recommended by the Spanish Academy of Sommeliers. Equipped with a day marker, this stopper consists of a metal ring around the circumference to be turned to the day the wine was closed (31 day indications). For optimal performance the bottle should be stored in an upright position.
