MYTIK DIAMANT, our technological cork solution for sparkling wines

picture of Mytik Diamant closureDIMENSIONS AVAILABLE: 30.5 x 48mm or 31 x 48mm

Product Presentation

MYTIK DIAMANT, a technological closure with a patented composition, manufactured from cork, treated by the exclusive DIAMANT process (eradication of 2,4,6-TCA by supercritical CO2 treatment).

A consistent and closure, without discs, that offers:

Excellent organoleptic performances :

  • A systematically controlled production batch for a releasable TCA(1)  rate per closure < QL (2)
  • A controlled and consistent permeability adapted to ensure a perfect effervescence.
  • A consistent closure that reduces taste variation from one bottle to another

Exceptional physical and mechanical performances

  • No disc separation
  • Easier compression and corking (3)
  • Regular insertion at bottling (3)
  • Reduced collapsing
  • Easy opening
  • Guaranteed dimensional recovery (mushroom form)

A closure that offers the positive aspects of cork:

  • An elastic, natural and ecological raw material.
  • A material that compliments wine.
  • A favourite with consumers.

A unique guarantee to assure your consumer of a positive wine experience whilst respecting tradition:

Cork tradition without the risk of cork taint

  1. - Guarantee per cork
  2. – QL : the Quantification Limit of the analytical method by gaseous chromatography is 0.5ng/L
  3. – In compliance with our bottling and storage conditions

  1. The above specifications assume compliance with manufacturer’s bottling and storage guidelines.
  2. QUANTIFICATION LIMIT (QL): the quantification limit by SPME/GC/MS is 0.5ng/L. This is an indicative value based on internal methodology, available upon request.
  3. DETECTION LIMIT (DL): the detection limit by SPME/GC/MS is 0.2ng/L. This is an indicative value based on internal testing methods, available on request.
  4. ACCEPTABLE QUALITY LEVEL (AQL): A2/R3 implies that for 32 corks tested:  the batch is accepted if a maximum of 2 corks only, show results outside our specifications and the batch is refused if 3 or more corks show results outside our specifications.
  5. The follow up frequency of this parameter is established in order to regularly evaluate our production batches.
  6. If the cork is washed.
