Fort Berens Winery, aka Fort Berens Estate Winery, is a winery and vineyard based in Lillooet, British Columbia, Canada.  Located in East Lillooet, near the site of the never-built Hudson's Bay Company's Fort Berens, it is the first successful attempt at a commercial winery in the area in the 20th Century and has won numerous awards for its wines.  It is the only commercial winery so far in the newly designated Lillooet wine region, though there are established local vinyards which are non-commercial and a history of wine cultivation at nearby Fountain.  It was founded by Rolf de Bruin, who immigrated to Canada with his family in 2008 from the Netherlands with his wife Heleen Pannekoek and their family.  They chose Lillooet over the Okanagan because land values there were a quarter what they were in the Okanagan, which is the centre of the BC wine industry.  Though the winery's first commercial vintage was made from grapes and wine brought in from the Okanagan, their first bottles made from grapes grown only in Lillooet were opened on April 30, 2012.  The winery first started operations in 2009. St. Clair Winery is an American winery in Deming, New Mexico, founded in 1984.
