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...
Vineyard yield forecasting is a key issue for vintage scheduling and optimization of winemaking operations. High errors in yield forecasting can be found in the wine industry, mainly due to the hig...
A cost efficient and accurate new system for vineyard yield forecasting that reduces the error below 10% per block, flexible and adaptable to any trellis system and extension
Intense aromas of blackcurrants and red fruits characterise the sensory profile of some red wines that are very popular with consumers. Over the last decade, researchers have shown that varietal th...
