Agglomerated cork stoppers are manufactured from natural cork granules of high quality through an extrusion process or a single moulding process in accordance of the standards of the International Code of Cork Stopper Manufacturing Practices (ICCSMP).

The agglomerated cork stopper joins the unique characteristics of the cork material with a very rigorous manufacturing process that allows achieving great levels of mechanical, sensorial and microbiological properties.

The cork granules size and density had been perfected to achieve a perfect balance of elasticity, homogeneity and sealing capacity. The small particles of cork granulates are cleaned in depth to fully guarantee the absence of any substance that can change the taste.

The agglomerated cork stopper characteristics provide an excellent sealing solution for fast consumption wines and other beverages (6 to 18 months) presenting good performance levels at an exceptionally competitive price.
