Efectos de los fenómenos producidos por el cambio climático sobre la calidad de los vinos

Abstract

[ES] Effects of phenomena caused by climate change on the wines quality. Climate change is an alteration of the climate that manifests by changes in the environment that also modify their characteristics. On the production side, especially in viticulture, climate change is exerting an increasing influence on the phenology of the vine also affecting grape composition. It also influences the vinification, oenological, chemical, microbiology and the organoleptic behaviour. In this work, the effects that global warming, due to the emission of greenhouse gases, is inducing in viticulture and oenology areas was analysed. The effects of temperature, carbon dioxide and solar radiation on the grapes ripening which produce an advancement harvest time with consequent changes in the composition of the grape influences the type of wine produced. Moreover, the problems generated by increased sugar and pH, along with decreased acidity are of major importance. Certain aspects concerning oak wood and its use in wine aging wine, as well as chemical changes associated with this process were also analysed.
