About
Terra Blanca sits on Red Mountain's southwest slope, working estate vineyards rooted in calcium carbonate soils—the kind of white, chalky material that shows up in serious wine regions worldwide. The Tuscan-style facility houses wine caves, a proper tasting room, and a library program pulling aged bottles straight from the cellar. Their Vineyard Grill runs a wood-fired brick oven serving Pacific Northwest ingredients with Italian technique, designed to pair with the estate's Bordeaux-style reds and other Red Mountain bottlings. Tours take you behind the scenes into production areas and caves. There's also a downtown Spokane tasting room in the Chronicle Building for city access to the estate wines.
The Oxto Edit
Oxto AIThis is one of Red Mountain's more polished operations, built around estate fruit from those white calcium carbonate soils the website won't stop talking about (and for good reason—it's the same stuff in Burgundy). The Tuscan architecture leans into luxury event territory with 10,000+ square feet of space, but the wine program has substance: library releases, proper tours through actual wine caves, and staff who know how to talk terroir without sounding like a brochure.
