Overall, the climate change scenarios given for the wine regions suggest potential for changes in varieties planted and wine styles and/or regional changes in viticultural viability. The wine quality issues related to climate change and shifts in climate maturity potential are seen mostly through a more rapid plant growth and out of balance ripening profiles. For example, if a region has a maturation period (ve ́raison to harvest) that produces optimum sugar, acid, and flavor profiles for that variety, then balanced and superior wines can be produced. If the climate is warmer than ideal, grapevines have more rapid phenological development that results in earlier sugar ripeness and loss of acidity through respiration while flavors
