Abstract
Mycotoxin risk in the grape product chain is primarily due to ochratoxin A (OTA) occurrence in wine and dried vine fruits. Aspergillus carbonarius and the A. niger group are the main agents of Aspergillus bunch rot of grape, and they, especially A. carbonarius, are responsible for OTA contamination worldwide. Fumonisin B 2 (FB 2 ) represents an additional potential mycotoxin risk in the grape-wine product chain and A. niger / A. awamori were recently reported as the FB 2 producers in grapes. A deeper understanding of the species diversity of black Aspergilli, together with specific knowledge of their ecology and epidemiology, can help to predict their occurrence. From this perspective several studies have been done regarding prevention and control of black Aspergilli and reduction of mycotoxin risk at all stages, from vineyard management to wine-making procedures. In this review a comprehensive overview of all these aspects is presented.
