In the Similkameen Valley, in Cawston.

From the website:

The conception of our winery began in the spring of 2003. After months of researching and debating alternatives, the decision was made to build Canada’s first strawbale winery in the Similkameen Valley.

Also solar powered:

We are proud of our green initiative here at Orofino. In the fall of 2012, we installed a solar power hybrid system that enables our tasting room and office building to be completely 100% run on solar energy. The system includes roof mounted solar pv panels to generate electricity to power the building as well as special solar panels that are able to heat all of our water needs in the building. The system has exceeded our expectations and we love to spend time watching our power meter spin backwards!
