Drew, Bucko gave you the answer. The product is marketed under the name " Private Preserve ". It also have carbon dioxide in it. You can preserve over 100 opened bottles with one can and as Bukster say, " It do work ". ( I think!. I bought a can in 1997 and have used it about 7 times, and always on the 2nd or 3rd bottle) I agree on the Vac-U-Vin. Absotively worthless like my cats. winoweenie
