Cork Stoppers

 

Technical Cork Stoppers

Technical corks were created for bottled wines which are consumed within a period of two to three years. They consist of a very dense agglomerate cork body with natural cork disks glued on one or both ends.
Technical corks with a disk on both ends, are designated 1+1 technical corks. With two natural cork disks, they are known as 2+2 technical corks, and with two disks on one end, 2+0 technical corks. An approved food contact glue is used to bond the disks to the agglomerated cylindrical body.

This type of closure is chemically very stable and mechanically very resistant. Their exemplary performance, bearing in mind the torsion to which they are submitted in the bottling and opening phases, is remarkable. Moreover, they have demonstrated their excellent sealing capacities throughout time, (Australian Wine Research Institute, Wine Bottle Closure Trial), maintaining the necessary SO2 free concentration in the bottle, whilst avoiding premature oxidation and yet remaining free of undesirable odours.

The most common sizes are:

 

44x23,5 mm

40 or 39x23,5 mm

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

Half bottles with 37,5 cl with the same neck finish

 

Short period of maturation

As the body of the cork closure is agglomerated, the quality of the technical cork is satisfactorily homogeneous.

However the visual standard of the cork disks used on the ends vary. The standard of these disks is generally classified in 3 grades: A, B and C, with C being the lowest grade. This classification can vary according to manufacturer.
