Abstract
Disclosed is a process for preparing cork articles, in particular cork stoppers for wine bottles, which involves treating cork with a phenol oxidizing enzyme. Preferred phenol oxidizing enzymes are laccase, peroxidase, catechol oxidase, and o-aminophenol oxidase. The treatment with a phenol oxidizing enzyme reduces the characteristic cork taint/astringency which is frequently imparted to the bottled wine.
