MYTIK DIAMANT, our technological cork solution for sparkling wines
DIMENSIONS 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
- - Guarantee per cork
- – QL : the Quantification Limit of the analytical method by gaseous chromatography is 0.5ng/L
- – In compliance with our bottling and storage conditions

- The above specifications assume compliance with manufacturer’s bottling and storage guidelines.
- 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.
- 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.
- 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.
- The follow up frequency of this parameter is established in order to regularly evaluate our production batches.
- If the cork is washed.
