Effect of temperature increase on vegetative development, berry and wine compposition on CV. Malbec, Mendoza

Abstract

Recent studies have predicted an increase of temperature in the main winegrowing regions of Argentina for the present century. A sustained increase in temperature may produce an advance in the phenological cycle, an increase in the concentration of berry sugar, in the alcohol content of the wines and a decrease in anthocyanins concentration, decoupling anthocyanins and sugars accumulation in the berry.
