Colmated corks are natural cork stoppers that have had the pores filled in with cork powder to offer a consistent appearance and good mechanical characteristics. Many colmated corks use a natural resin or water-based glue along with the cork powder to fill the lenticels, improving sealing performance. Colmated corks are an economic natural cork option that still offer the homogeneous texture of high quality grade cork.
