Agglomerated cork stoppers are entirely made of granulated cork, derived from by-products that are a result of the manufacture of natural cork closures. Agglomerated cork stoppers can be manufactured by individual moulding or by extrusion. In both methods, approved food contact glues are used to bind the cork granules together.

Agglomerated corks are an economical solution in assuring good sealing for a period that should not, in general, exceed 12 months. Besides the economical advantage they represent, for low-priced wines with a high rotation, these corks are completely batch homogeneous. As this product is the result of a highly industrialized process, the only category variation of agglomerated cork closures is in the chosen cork granule size and in the surface treatment used.


Normally they are manufactured in the following sizes:


44x23,5 mm

38x23,5 mm

33x23,5 mm

Bordeaux, Burgundy or Rhône
type bottle (75 cl) with a CETIE* or Italian specification neck finish
