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).

A new device for stabilisation of white wines throughout a continous flow system

Parpinello, G.P., Ricci, A., Serantoni, M., Balducci, A., Ragni, L., Versari, A.; University of Bologna, Italy

Proteins occurring in wine originate from several sources during the winemaking process. Protein content in wines ranges from traces up to hundreds of mg/L, and may cause physical instability in wh...

About the Role of the Bottleneck/Cork Interface on Oxygen Transfer

Aurélie Lagorce-Tachon et al. J. Agric. Food Chem., 2016, 64 (35), pp 6672–6675

The transfer of oxygen through a corked bottleneck was investigated using a manometric technique. First, the effect of cork compression on oxygen transfer was evaluated without considering the glas...

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...
