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.
Clean: Through an exclusive patented process, cork "de-aromatization", Diam and Mytik Diam are the only cork closures that are sensorially neutral, freed from the molecules causing organoleptic deviations including TCA, responsible for cork taint (TCA releasable ≤ 0.3 ng/l).
The manufacturing process for Diam, Mytik Diam and Altop guarantees each single closure (not an average value per batch).
Consistency: The manufacturing process provides all the closures with the same physical characteristics. It guarantees a perfect consistency in the bottling line as well as during the aging of the wine.
Choice: Diam closures are designed to meet all expectations regarding the evolution of the wine, the varietal expression and the duration of conservation. Available in different levels of permeability, they master the oxygen transfer rate and their constancy throughout bottled life.
