Wine quality: Difference between revisions
Created page with "'''Wine quality''' refers to the degree to which a wine meets accepted standards of excellence, balance, typicity, and sensory appeal, as evaluated through chemical, sensory, technical, and cultural criteria. Unlike purely analytical measures, wine quality is a multidimensional concept shaped by viticulture, winemaking, ageing, market context, and consumer perception. It is therefore not an absolute property, but one that combines objective parameters with subjective jud..." |

Wine quality is strongly conditioned by grape quality, which in turn depends on site, climate, vine balance, and harvest timing. Factors such as light exposure, water availability, crop load, and phenological timing influence sugar accumulation, acidity, phenolic maturity, and aroma precursor development.<ref>Keller, ''The Science of Grapevines'', Academic Press, 2015, ISBN 9780124199873.</ref> | Wine quality is strongly conditioned by grape quality, which in turn depends on site, climate, vine balance, and harvest timing.

Canopy management practices, including shoot positioning and leaf area control, play a central role in moderating microclimate and supporting consistent ripening, particularly in marginal or variable climates.<ref>Smart & Robinson, ''Sunlight into Wine'', Winetitles, 1991, ISBN 9781875130033.</ref> | [[[[Canopy]] management]] practices, including shoot positioning and leaf area control, play a central role in moderating microclimate and supporting consistent ripening, particularly in marginal or variable climates.<ref>Smart & Robinson, ''Sunlight into Wine'', Winetitles, 1991, ISBN 9781875130033.</ref> | ||
Climate exerts a decisive influence, both at regional scale and vintage level. Temperature, solar radiation, and water balance shape the achievable style and structural balance of wines, and are increasingly discussed in relation to climate change and long-term quality adaptation.<ref>Gladstones, ''Viticulture and Environment'', Winetitles, 1992, ISBN 9781875130101.</ref> | Climate exerts a decisive influence, both at regional scale and vintage level.

From a chemical perspective, wine quality is associated with the balance and interaction of acids, alcohol, sugars, phenolics, and volatile compounds. No single compound defines quality; rather, it is the harmony between structural elements that underpins positive sensory perception.<ref>Waterhouse, Sacks & Jeffery, ''Understanding Wine Chemistry'', Wiley, 2016, ISBN 9781118627808.</ref> | From a chemical perspective, wine quality is associated with the balance and interaction of acids, alcohol, sugars, phenolics, and volatile compounds.
