In Santa Barbara County, the north-south coastal range of mountains abruptly turns to run almost east-west for 50 miles, framing the valleys in a unique transit to the Pacific Ocean. This is the only stretch of land from Alaska to Cape Horn constituting an east-west traverse. The unique topography allows the flow of fog and ocean breezes to shape distinct microclimates and makes the region one of the coolest viticultural areas in California. However, warmer daytime temperatures in the inland areas allow a wide variety of winegrapes to be grown. Terrain and climates vary widely, from steep, wind-swept hillsides to rolling inland valley vineyards where summer temperatures often reach the century mark.
