The Cork Pops Wine Preserver helps preserve opened bottles of wine by protecting them from oxidation. Using a food-safe inert gas formula, it creates a protective blanket over the wine to help preserve flavor, aroma, and freshness for longer. Unlike vacuum wine preservers that remove air, the Cork Pops Wine Preserver uses nearly pure nitrogen with traces of argon and carbon dioxide to displace oxygen. This helps protect wine without changing its flavor or aroma. Ideal for red wine, white wine, dessert wines, ports, aperitifs, sake, gourmet vinegars, and infused cooking oils, the Cork Pops Wine Preserver is simple to use and helps extend freshness after every pour. Simply insert the patented injection tip into the bottle and press three times. The inert gas gently blankets the wine, reducing oxidation and helping preserve taste and bouquet. Replace with an airtight stopper after use and store the bottle upright.
