They are just another "value" you will find in the bottle. The latest innovation in the wine sector.

A controlled permeability membrane is put between the properly punched aluminium cap and the inside of the bottle in order to enable the micro-exchange of the oxygen.

All the advantages of the screwcaps combined with the natural permeability of the natural cork:

• Constant results, reliability
• Uncorking without corkscrew
• Easy to close the bottle again
• Perfectly aged thanks to the controlled micro-oxygenation
• Total absence of defects, no cork taint
• Excellent aromas and flavours, no sensation of reduction or oxidation
