#8 agglomerated corks are slightly smaller than the standard #9 corks. They are often used with hand corkers that cannot compress the standard #9's, or for bottles with smaller necks. Agglomerated corks are made from small cork pieces held together with a food grade binder. The Acquamark cork line is a high quality colmated cork. These corks have the ageable lifespan of Natural Cork, but are closer to the price of an agglomerated or overrun cork.
