Our Corks are
manufactured from 100% natural Cork harvested in Portugal.
The quality of Corks is measured by the lenticels (small crevices that
occur in all natural cork).
The fewer the lenticels, the higher the grade of Cork. Both grades of
Cork will seal dry goods and solids (sand or salt, for example) in a
container. If sealing liquids where more secure seal is important, we
recommend only using XXXX Premium Grade Corks.
Premium Grade XXXX Corks are more expensive, but they are far superior
to Standard Corks
in mechanical strength, seal, and appearance.
Please Note: Cork sizes & Rubber Stopper
sizes are NOT the same.
( for instance, a # 4 Rubber Stopper and # 10 Cork are about the same
