The effects of two different operations in the vineyard (basal leaf plucking and head trimming) on the synthesis of aromatic precursors in the grape and their impact on wine aroma have been studied and compared with a control sample. The study was carried out over two consecutive years with four different varieties. Glycosidic precursors were analysed in grapes and volatile compounds were studied in the wines.
Sugar loading can be defined as the accumulation of the quantity of sugar per berry, expressed as milligrams (mg) per berry, from véraison onward. Véraison corresponds with the onset of fruit maturation.
Optimal maturity of grapes depends on multi-facetedcriteria. Several important classes of compounds are biosynthesized during the berry growth period, before and/or after véraison (aromatic precursors, phenolics, hormones, organic, acids, etc.), while others are provided by roots and/or leaves (water, minerals, sugar, etc.).
