•The link between seasonal trend, grape ripening and wine aroma, was assessed.•Barbera and Pinot Noir wines from early harvested grapes were produced.•Norisoprenoids were quantified in wines during fermentation and after three months.•The highest β-damascenone content was detected in wines from less mature grapes.•β-Damascenone content increased during wine shelf life.
