Aromatic potential of grapes and wines: nature, structure, technological relevance and analysis methods

Rémi SCHNEIDER, INRA-IFV Montpellier, France

Wine aroma results from the precursors found in grapes, these constitute the so called “aromatic potential”. The compounds that determine the aromatic potential can be divided into 4 main categories, according to their origin and chemical nature: carotenoids, cysteine conjugates, DMS precursors and glycosides. The seminar covers the diverse families of precursors, specifying in detail the components of each family, quantifying their presence and the conditions that determine it. In the final part of the presentation the analytical methods available for each family are analyzed, some of which are already applied during production to quantify the aromatic potential of the grapes and hence predict the potential quality of the resulting wine.
