PRIVATE PRESERVE

Prevents oxidation or spoilage of wine by using the inert gases used by wineries worldwide - Harmless Nitrogen(N2), Carbon Dioxide(CO2), and Argon(AR). Protects fine wine, port, sherry, sake, cognac, single malt scotches, oils and vinegars for days, weeks, even months. Works by laying down a heavier than air blanket of protective gas on the wine's surface that blocks out oxygen, preserving the taste and bouquet in bottles and decanters. (Full can feels empty. Can is empty when hissing stops. 120 plus full uses.)
