Mountain Dome Winery, a family-owned sparkling wine producer in the Foothills area of Spokane County, helped create Grande Ronde Cellars back in the late 1990s, and now Grande Ronde is widely regarded for producing elegant red wines. This year, the pattern is repeating itself with Grande Ronde and Mountain Dome giving life to three new labels, under cooperative arrangement in two cases with new winemaking families.
