Dunnigan Hills

Located in the northwestern portion of Yolo County, the Dunnigan Hills AVA encompasses 69,000 acres with roughly 1,300 acres hosting vines. The summer days are hot, averaging between 95°F and 98°F, but at night the temperatures cool to between 55°F and 65°F. This tremendous drop in temperature allows the grapes to cool, which preserves the grapes' natural acidity. The soil composition is a gravelly loam in the upper hills, whereas in the valleys it is silty or chalky clay loam over sandstone. Dunnigan Hills is home to only one winery, R. H. Phillips.
