This appellation is widely described as sprawling as it encompasses half or more of the county. Our fruit comes from two of the coolest, most coastal parts of this appellation: the low coast, west of Sebastopol on the edge of the Petaluma Gap; and the high coast, the first or second ridge inland from the ocean farther to the north. These sites are united by the direct influence of the Pacifics cool, marine air, delaying ripening well into October.
