REQUIREMENTS
The Diam cork is an active partner in the
evolution of a wine under its “care.”. By twea-

to last up to 30 years. The filler plugs the tiny
gaps to create a consistent structure. An “even”
structure means consistent aging. Not surpri-
singly, producers offering the most long-li-
ved, collectable wines are Diam fans and have
contributed significantly to the company’s
growth.
Depending on whether the wine is drunk
within 6 months or after 30 years, on whether
it is red, rosé or white, whether it is more or
less sensitive to oxidation, the winemaker can
select the corks according to different levels of
permeability and different lifespans.
The oxygen supplies during the first months
(OIR = Oxygen Initial Release) and over the time
(OTR = Oxygen Transfer Rate) are quantified for
each stopper recipe. For more information,
