A new American Viticultural Area is being considered for one of the most distinctive terroirs in America, one that has produced unmistakably great wines. Unfortunately, most of the actual wines won't be able to use it.
On an old riverbed south of the town of Walla Walla, cobblestones litter the ground, in some areas totally obliterating any view of the soil. Locals have taken to calling this part of the Walla Walla Valley AVA "The Rocks." Vines struggle to grow, resulting in tiny grapes of amazing flavor intensity. And yes, the wines show the sort of flavors that fall under the heading of "minerality," although to my taste it's more like black olive and tar.
The stones drew Christophe Baron to plant grapes in the region, just north of the town of Milton-Freewater, Ore., starting in 1997. He named the vineyard Cailloux, French for stones, and planted six others in the area. They produce the grapes for his highly coveted Cayuse wines, no stranger to the Wine Spectator Top 100.
