Consumers can enjoy the appearance and feel of real cork with our Pearl® Micro-agglomerated cork. It offers a natural alternative to synthetic stoppers and screw caps at a comparable price.
Pearl® corks demonstrate our continuing commitment to sustainability and recycling. Cork material remaining after punching solid (natural) wine corks is carefully sorted and processed. A series of operations reduces the material to uniformly sized particles. Dust and particles that do not meet the narrow size tolerance required are saved for use in other non-M.A. Silva recycled cork products. We use only FDA-approved food-grade bonding agents.
Pearl® Micro-agglomerated corks are designed primarily for price-sensitive still wines, light sparkling wines and beer, intended to be consumed shortly after purchase. This product meets the same quality standards as our natural and technical wine corks, but at a price point competitive with screw caps and synthetic stoppers.
Pearl® corks are offered in 24x38 mm and 24x45 mm sizes.
The product is available in two granule sizes.
Pearl® corks are recommended for wines which will be consumed within two to three years.
