Our Story

Bartier Bros. was founded on a shared belief that great wine begins in the vineyard and must speak clearly of where it is grown.

Raised in the Okanagan Valley, Don and Michael Bartier share a deep and enduring connection to this place. Its landscape, climate, and evolving wine culture shaped their early lives and ultimately the direction of their work.

Bartier Bros. was built on a clear belief: great wine must reflect where it is grown. The South Okanagan offers rare growing conditions which shape its wines. High-altitude vineyards. Intense, northern latitude sunlight, cool nights, low humidity, temperature moderating lakes, and young soils layered over glacial till.

Cerqueira Vineyard

We farm Cerqueira Vineyard, a site that exemplifies the precision and care behind our wines. Located on the lower side of Black Sage Road between Oliver and Osoyoos, this gently west-facing vineyard sits on heavy, slightly sandy loam soils with granite cobbles coated in calcium carbonate. The vine roots reach deep into these rocks, which impart subtle minerality and energy to the wines.

Cerqueira is more than just land – it is the foundation of our wines. Every decision in the vineyard, from site selection to long-term care, is made with a deep understanding of what makes this site exceptional.
