Studies carried out in the wine belt (wine-growing regions between the 30º and 50º parallels) indicate that the climate influences the quality of the grapes. In cold climates, there is less sugar and more acidity; in warm climates, there is more sugar and less acidity, resulting in more mature flavors. Optimal ripening of the grapes, with precise sugar and acidity levels, allows the quality and style of the wine produced to be maximized.
