How to choose size: As a general rule, choose the cork with the biggest bottom diameter smaller than the inside opening diameter of your bottle, hole, etc.

The cork grade is determined by the amount of lenticels (crevices). Extra Select are among the highest grade available, meaning they have smaller and fewer lenticels than a XXX Standard or XXXX Premium grade. Agglomerated grade corks are made from the granulated by product of natural cork production which has been bound together using pressurization.
