#9 x 1-3/4 in long corks are the standard size wine bottle corks. Premium quality natural corks are punched from a single piece of the Cork Oak bark, making a very strong and attractive cork that can be used for wines being storred for 10 years or more.
Corks are treated with a food grade wax and silicone coating before being packaged by the manufacturer. To use, corks may be dipped briefly in a sanitizer solution and then corked immediately. Do not soak or boil corks as this can remove the silicone coating, making them difficult to remove from the bottles.
