Good efficiency of grape worm control measures
The experiments carried out by the ICV in 2001 and 2002 clearly showed that the efficient control of the grape worm could lead to an 80% reduction in Ochratoxin A levels as compared with a control wine containing over 2 µg/l.
In 2001, several plant protection strategies were compared on this Cabernet Sauvignon plot in a study comprising 4 replicates for every treatment. The grapes obtained from each treatment were vinified in the pilot winery of the ICV and were subject to Ochratoxin A analyses. Among the treatments tested, 8 involved the usage of a preventive ovicidal insecticide (Flufenoxuron), and these ones resulted in an average Ochratoxin A reduction of 82% in the wines upon bottling.
The seasonal character of harvests limits winemaking considerably, especially oenological research. Thus, conserving sterile musts during the whole year to carry out experiments is certainly a very...

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...
