STABILIZING COLOR IN RED WINES (II Part)
Daniel GRANES, Jacques ROUSSEAU, Lucile BLATEYRON, Caroline BONNEFOND
Contrary to what one might think, color stabilisation can not be completely dissociated with extraction for at least 3 reasons. First the actions carried out during vinification with maceration, as...

FINDING NEW PROTEINS RESPONSIBLE OF “NATURAL” PROTEIN INSTABILITY IN WHITE AND ROSE’ WINES
CALEGARI Giovanni1, MANTEAU Sébastien2, POINSAUT Philippe2, SCOTTI Barbara1
Wine proteins may have different origins: the grape, from which the majority is originated, the yeast, the bacteria and the enological treatments, as in the case of over fining. Although proteins are

OXYGEN ADDITIONS DURING VINIFICATION AND THE IMPACT ON WINE. 2ND PART
Michel VALADE, Isabelle TRIBAUT-SOHIER, Denis BUNNER, Clément PIERLOT, Dominique MONCOMBLE, Dominique TUSSEAU
In the first part of this article (1) we brought up ideas regarding additions of oxygen during the winemaking process, before the bottling phase. These additions are quite different from one facility

OXYGEN BRINGS NEW LIFE TO CLOSURE DEBATE
Nancy MILLS, Paulo LOPES and Miguel CABRAL
The chemistry of winemaking and wine development is complex and not fully understood. However, it is clear that oxygen exerts a significant influence during most if not all stages of the process. In

USING HIGLY ABSORBENT YEAST HULLS IN WINE FOR ELIMINATING CORKED AND MUSTY TAINTS
Olivier FERNANDEZ, Céline FAUVEAU, Patrice PELLERIN DSM Food Specialties, Carole PUECH, Patrick VUCHOT, Stèphane VIDAL, INTER RHÔNE
Cork and musty taints are defects currently occurring in wine. This situation applies to all wine-growing areas and is not a new problem. In fact, the issue was raised by Georges Jacquemin in 1903 in
