Natural cork stoppers

Natural cork stoppers are obtained through the most natural process of punching the entire cork strip. Because they are the most natural corks, they are the most premium corks.

They can and should be used with all kinds of wines, regardless of the ageing period and bottle shape. They are the most suited for the gradual ageing of wines.

Natural cork stoppers are the company’s most widely sold product, and M.A.SILVA stands out in the market as a worldwide reference in natural cork stoppers.
