Abstract. Cork polyphenols susceptible to migrate into wine were studied in ten different types of natural and agglomerated cork stoppers, made of one and several pieces. Both low molecular weight polyphenols (LMWP) and ellagitannins (ET) were analysed by HPLC. Moreover, the molecular weight distribution was determined in tannic fractions. The LMWP gallic, protocatechuic, vanillic, caffeic, ferulic and ellagic acids; vanillin, protocatechuic, coniferilic and sinapic aldehydes, aesculetin and… 
Migration of phenolic compounds from different cork stoppers to wine model solutions: antioxidant and biological relevance
Considering the enological interest of cork, this study aimed to identify and quantify the phenolic compounds able to migrate from different classes (natural cork stoppers “Flor” and “Third” quality
Variation in the Phenolic Composition of Cork Stoppers from Different Geographical Origins.
Variability in the polyphenol composition of cork stoppers is not significantly influenced by geographical location but probably may be more related to the plant genetics, tree age, and phytosanitary and edaphoclimatic conditions.
Migration of Tannins and Pectic Polysaccharides from Natural Cork Stoppers to the Hydroalcoholic Solution.
Ellagitannins, condensed tannins, and pectic-derived polysaccharides were removed from natural cork stoppers using hydroalcoholic solution. Two main populations of migrated compounds were determined;
Phenolic Compounds in Cork-Closed Bottle-Fermented Sparkling Wines
Bottle fermented sparkling wine in South Africa is known as Methode Cap Classique which is based onthe method used in France for Champagne. The use of cork, instead of a crown cap during the
Reactivity of Cork Extracts with (+)-Catechin and Malvidin-3-O-glucoside in Wine Model Solutions: Identification of a New Family of Ellagitannin-Derived Compounds (Corklins).
This new family of compounds that were found to result from the interaction between ellagitannins in alcoholic solutions and (+)-catechin were structurally characterized by mass spectroscopy, nuclear magnetic resonance, and computational methods.
Cork-wine interaction studies: liquid absorption and non-volatile compound migration
Aims: To provide a better knowledge of cork-wine interaction, focussing on absorption of liquid by the cork stopper and overall migration of non-volatile compounds from the cork-stopper to
Wine Oxidation and the Role of Cork
The present review aims to show the state of the art of oxidation mechanisms occurring especially in white wines by taking into account knowledge from different fields in relation to the subject. It
Cork: Current Technological Developments and Future Perspectives for this Natural, Renewable, and Sustainable Material
Cork is the bark of Quercus suber L., the cork oak tree. It is currently explored for different industrial applications, of which stoppers for the wine industry is the most representative and
