Natural Corks
Cylindrical and Tapered Natural Cork Stoppers
Natural corks by Subermex are the only sealing material which allow wine to "live" and mature in the bottle over extended time. They are "punched" from specially selected corkwood, carefully inspected for flaws, washed, sterilized, and printed or fire branded. There are seven standard grades of natural corks carefully sorted into respective quality grades, first by automatic laser sorting machines, followed by final manual hand sorting. Natural corks are available in a wide variety of both standard and custom sizes, the most common being 45 mm long (1-3/4") x 24 mm diameter and 38 mm long (1-1/2") x 24 mm diameter. The technical specifications are the same for all sizes of natural cork stoppers.

Other Facts
There are several different types of natural corks available. Type selection is dependent on the type of wine being sealed and the expectant length of time before the wine is consumed. Other factors determining selection and treatments of natural cork stoppers include bottling speed, still or sparking wines, sweet or dry wines, red or white wines, bottle size and type. Subermex can recommend the best type, size, quality, printing or branding, and surface treatments to ensure successful results.
