Former dentist Jon Martinez has become a full-time vigneron; he is the owner and grower of French Creek Vineyard near Prosser and two years ago he purchased 21 acres in Yakima Valley. Maison Bleue is dedicated to the production of terroir-driven wines from designated vineyards and appellations located across Washington State. They focus primarily on Rhone varieties such as Grenache, Syrah, Roussanne and Viognier, as well as Chardonnay. The winemaking is an uncompromised style of traditional techniques, gentle handling and a modest use of French oak. Maison Bleue Winery is located in Prosser, the historic heart of Washington’ss first appellation.
