EVACORK® COLMATED CORK STOPPERS
Colmated cork stoppers are a response to the winemaker’s challenge of maintaining the attractiveness of the wine with a natural cork stopper, at a very competitive price.
These stoppers allow wineries to take advantage of the preferred use of natural cork stoppers. Fine cork powder from M.A.SILVA production is used to colmate the corks, in order to fill the small gaps in natural corks with lower visual quality.
EVACORK® stoppers are our response to this specific segment.
The production process of colmated cork stoppers includes advanced technologies that guarantee the quality of the stopper.
Sterilisation and vaporisation of raw materials
Extraction of volatiles and sensory standardisation
Sterilisation and elimination of microorganisms
