Microcork stoppers

These stoppers combine end discs of best quality natural cork with cylinders formed, using our special and costly agent and centrifugal moulding machinery, from specially selected small (0.2mm) granulate from the very best cork material. Produced in the same 24mm diameter as natural stoppers, due to their elasticity, and in lengths of 40 or 44mm.

MICROCORK provides excellent elastic performance, allowing the wine to 'breathe' but not to oxidize. Due to its perfectly flat surface, it is ideal for imprinting with complex motifs.

Usually produced as a fully washed version.

Perfect for wines stored for up to 4 - 6 years.
