Permitted Varieties
Okanagan Valley GI
Overview
Okanagan Valley is British Columbia’s flagship wine region and one of the world’s most dramatic wine-producing landscapes, with vineyards stretching 200 kilometers along a chain of lakes in Canada’s only true desert. This remarkably diverse region produces everything from elegant Pinot Gris and Riesling in the north to powerful Syrah and Cabernet Sauvignon in the sun-baked south. The combination of extreme latitude (49-50°N), intense summer sunlight (17+ hours), and dramatic terroir variation creates wines of surprising complexity that are increasingly earning international recognition.
