Preventive oenological measures: rather limited impact of technological options
The grape Ochratoxin A potential is almost entirely responsible for the contamination levels found in wines. No vinification protocol can significantly reduce Ochratoxin A levels in wines produced from very contaminated grapes.
Thus, the potential risk of Ochratoxin A contaminations does not question the good vinification practices to be implemented in order to achieve the various technological and sensory objectives.
The vinification study carried out in the ICV pilot winery allowed to assess the absence of an influence, or the presence of a slight effect of different factors on wine Ochratoxin A contaminations.
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...
