The importance of climate for winegrowing is unbelievable. Although there have been many advances in winemaking, climate has remained the one element growers cannot control and which will determine the overall style of a wine as well as the quality of any given vintage. According to climatologists when studying the history of wine, it is very clear that present-day winegrowing regions have been established according to favourable climates that have fostered the cultivation of different grape varieties. For instance, Pinot Noir grapes are usually grown in cool climates with the temperature during the growing season varying between 14°C and 16°C. On the other hand, Cabernet Sauvignon is grown in relatively warmer climates with temperatures ranging from 16.5°C to 19.5°C.
