WHAT DEFINES A COOL CLIMATE WINEREGION?
There is no consensus on what defines a cool climate wine region. Certainly average temperature over the growing season is important (October-April in Southern Hemisphere, April- October in Northern), but so too are such aspects as months of growing season, rainfall distribution, wind exposure, frost prevalence and sunlight hours. Jones and Schultz(2016) believe an average growing season temperature (GST) should be between 13°C and 15°C.
Below 13°C means only non- vinifera (hybrid)varieties will prosper, and above 15°C tends to result in wines that are significantly less acidic.

COOL CLIMATE WINES
A cool climate zone does not guarantee a cool climate wine. If its a relatively cool zone depends on the grape variety.
