Top 10 cool climate wine regions

As the International Cool Climate Wine Symposium approaches, Sally Easton MW takes a look at some of the world’s most prominent cool climate regions, counting down through the coolest of cool climate regions based on GST temperatures.

Growing season temperature (GST) is the average temperature for each month of the seven month growing season (October to April in the southern hemisphere; April to September in the northern hemisphere), divided by seven. Typically, cool climate refers to regions with a GST of between 13 to 15°C. Here, we have taken into consideration cool climate regions that produce wine of a high enough quality and in enough volume to be commercially viable, even if not widely exported.

“GST came about because most of the general public and even….
