Abstract:
In view of climate change, the scheduling of an early harvest may be an agronomic option to limit wine alcohol,
provided that a satisfactory content of secondary metabolites can be ensured in grapes. To better understand the
link between grape ripening, seasonal trend and wine aroma, the aromatic expression of Barbera and Pinot Noir
wines produced with early harvested grapes was assessed. Attention was focused on C13 norisoprenoids during
both alcoholic fermentation and after three months of storage. At the end of fermentation, the highest β-damascenone
content was detected in wines obtained from less ripe grapes, the content subsequently increased
significantly after three months of storage; however, the levels of β-ionone decreased significantly during the
same period. The reduction of wine alcohol as a result of harvesting earlier, especially for Barbera, was associated
with optimal aromatic levels as well as good technological parameters.
