Cork Janosa
cork stopper producers
A stopper produced from small (0.2mm) granulate, specially selected from the very best cork material and formed using a special and costly agent and centrifugal moulding machinery. Due to its elasticity, this stopper is produced with a 24mm diameter, like a natural stopper, and in lengths of 40 or 44mm.
STERICORK provides excellent elastic performance, allowing the wine to 'breathe' but not to oxidize. Due to its perfectly flat surface, this stopper is ideal for imprinting with complex motifs. Also, with its chamfered ends it works perfectly for lower-tech bottling plants or bottles, where other stoppers will often leave cork fragments in wine. Normally supplied fully washed.
Perfect for wines intended for storage up to four years.
