The Osoyoos Larose winery is located in Okanagan Valley in British Columbia in Canada and is a joint venture between Vincor and the big Bordeaux wine company, Groupe Taillan, whose major French property is Château Gruaud Larose.

Osoyoos Larose debuted initially with its first label, Le Grand Vin, even though the grapes for the 2001 vintage came from three and four-year-old vines. Winemaker Pascal Madevon believed he had first label quality right from the starting gate.
