The Okanagan Valley extends from the border by Osyoos in the south to just above Salmon Arm in the north for a total distance of approximate 180 km.
The Okanagan Valley is home to the oldest surviving BC winery that has been producing wines since 1934. In 1934 it started out as the Domestic Wines and By Products, to be renamed as Calona Wines in 1936.
Over 90% of British Columbia grapes are produced in the Okanagan Valley and more than 190 British Columbia wine and cider producers are located in the Okanagan Valley.
The wine regions are located in southern British Columbia. There are five official viticultural areas, recognized by the VQA.
