abstract

  • Wine quality, regardless of how defined, is impacted by grape quality. Grape quality depends on various metabolites, timing, and completeness of ripening, and the ripening synchrony of skins, seeds, stems, and pulp suited to the type and style of wine desired. Early and late season light, temperature, and water conditions are particularly important in determining the composition of wine grapes; however, there is no single definition for the correct degree of ripeness or quality. Both depend upon the winemaker’s intentions, wine style, secondary grape metabolites aroma/flavor and phenols, structural integrity, and longevity. This chapter considers grape maturity evaluation issues of importance in stylistic winemaking.
