Our Castle Rock Pinot Noir was produced from grapes grown in Northern California’s beautiful Mendocino County, where vineyards were first planted in the early 1860’s. Here, the headwaters of the Russian River carve a fertile and rugged landscape. The warm summers, cool springs, crisp falls and wet winters make ideal growing conditions for Pinot Noir grapes, in a climate similar to that of the Burgundy region of France, where the grapes were first established.
