Diam Closure for Still Wine
Diam, our technological cork for still wines.
Diam 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.
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.
By preserving the wine’s aromas throughout its maturation, Diam is the closure of choice for a successful tasting experience every time!
Diam comes in 5 different permeability types—download the information sheet for details.
