The Vacu Vin Universal Vacuum Bottle Stopper preserves wine by creating an airtight seal. Simply insert the stopper into your favourite bottle and pump until the patented “Click” is heard, signaling the optimal vacuum level has been reached. Once sealed, the bottle can be stored upright in the fridge, on the countertop, or in a cabinet. Made for prolonged use, this durable Wine Saver helps slow oxidation and encourages enjoying wine more consciously.
