Maison Bleue produces wines from Columbia Valley, Washington's premier growing region. The winery focuses on Rhône-style blends and single varietals, drawing on the region's capacity for ripe, structured fruit. Gravière Upland Vineyard, a blend of Mourvedre, Grenache, and Syrah, represents the house style—a wine that has attracted attention from Wine Enthusiast, Wine Advocate, and Decanter. The Voyageur Yellow Jacket Vineyard Syrah showcases the varietal's dark fruit and spice potential in this terroir, while La Montagnette Upland Vineyard Grenache offers a more delicate expression of the same vineyard site. Each wine reflects the winery's commitment to vineyard-designated bottlings, allowing the specific character of Columbia Valley's microclimates to emerge.
