The Rhône-inspired Cayuse Cailloux Vineyard is a single-vineyard Syrah produced in the Walla Walla Valley, Washington State. `Cailloux` means `stones` and refers to the stony soil of this part of the valley, which reminds Burgundy-trained winemaker Christophe Baron of the galet stones of the southern Rhône. A small proportion of Viognier is added to give this silky, umami-rich Syrah a distinctly northern Rhône feel. Cayuse Vineyards was the first winery in the Walla Walla Valley to fully implement biodynamic farming in its vineyards.
