Technical Wine Corks

Choose your Dimension

Technical cork stoppers are the association of an agglomerated cylindrical cork body with a disc of natural cork on each edge, making sure the liquid inside the bottle only have contact with natural cork of high quality.

The rigorous production process makes possible that any change to the wine tasting is virtually reduced to zero.

By mixing the natural cork and agglomerated cork elements this is a unique type of stopper offering a bottling solution for wines with a medium aging time in bottle (2 to 3 years).
