DIAM, our technological cork for still wines and it is the only cork closure that provides both a perfect homogeneity between one bottle and another and perfect control over the different levels of permeability. The DIAMANT® method also provides incomparable sensorial neutrality.

The reference #1 corks are the traditional bottle closure for wine intended for long term maturation and storage. A silicone coating on the cork reduces the drag when it slides through the corker. Newly purchased corks in an unopened pack do not require sterilization. To soften the corks for easier insertion by manual corkers, only then place in a colander over a bucket and allow boiled water vapour to rise up through the corks for a few minutes before using.

No 2 - 1 to 3+ years
No 5 - 1 to 5+ years

Tested and approved by many international laboratories, Diam is an innovative closure that combines the tradition of a cork stopper and the mechanical and organoleptic security of a technological closure:

• TCA taint-free (below the limit of quantification of 0.3 ng/l) and many other molecules responsible for sensorial deviations.
• Optimum bottling line (insertion) performance and unsurpassed elastic recovery.
• Prevents leakage, seepage or dust risk.
