Effect of Agronomic Techniques on Aroma Composition of White Grapevines: A Review

Climate change with rising temperatures and the unpredictability of rainy events during ripening leads to tough challenges for winemakers in preserving quality white grape varieties. Grape is a complex concept that mainly refers berry chemical composition, including secondary metabolites such as aroma compounds berries play key role identity wine. Terpenes, thiols, C13-norisoprenoids, methoxypyrazines, nonterpenic alcohols are most important grapes several them can be found free volatiles or bound glycoconjugate molecules. Agronomic practices vineyards, biostimulant application, irrigation, defoliation, training systems, foliar fertilization, bunch thinning, have positive effect on their concentration. This review aims highlight aromatic characteristics utilized cultivars focus agronomic techniques vineyard enhance, implement, intensify characteristics. The purpose this paper therefore investigate state art regarding exaltation scientific literature through sustainable techniques, but further future investigations considered necessary given uncertainty concerning some mechanisms biosynthesis correlation practices.
