According to the Wine Economics Research Centre at the University of Adelaide, the wine industry produced around 27 billion litres of wine in 2014. That's enough for almost four litres of wine for every single person on earth. Remarkably, although there are literally thousands of grape varieties suitable for
making wine, twodozen varieties accounted for roughly 85 per cent of the world's wine production.
Italy is a welcome exception to the increasing uniformity of the wine world. There are over 2,000 varieties of wine grapes currently cultivated in Italy. Many never make it far from their immediate environs. Those that do make it to North America are often lost in the veritable sea of Cabernets and Chardonnays that crowd the typical wine store
