OPTIMIZATION OF MICRO-OXYGENATION WITH LYSOZYME

OPTIMIZATION OF MICRO-OXYGENATION WITH LYSOZYME

Christophe Gerland

This article presents a practical application of lysozyme to increase the efficiency of micro-oxygenation in the Clairmonts wine cellar, near Tain l’Hermitage After several years of developments, the utilization of micro-oxygenation combined with lysozyme has allowed the production of wines reflecting all the qualities of the Northern Côtes du Rhône Syrah (AOC Crozes Hermitage), while improving the mouthfeel. In this particular case, the returns obtained on the product have exceeded the investments (in efforts, materials and consumables such as oxygen and lysozyme).

An electrochemical method for real time measurement of polyphenols during winemaking

By Christine Pascal, Nelly Champeau, Jean Baptiste Diéval, Stéphane Vidal; Vinventions, Enology team, France

Polyphenols are known to play a major role in must oxidation as well as in wine aging and oxidation. However, they are difficult to measure in the cellar due to lack of adequate technology. Therefo...
