The unique, transverse nature of the valleys of Santa Barbara Wine Country provides a patchwork quilt of microclimates and terrains, resulting in one of the most diverse grape growing regions in the country. The valleys in the Pacific coastline actually run east-west rather than north-south, and both the coastal Santa Ynez Mountain range and the more interior San Rafael range are transverse too. Because of this geologic oddity, the ocean breezes sweep eastward, channeled by the hills and mountains that ring the region. Heading east into the foothills, the temperatures are warm during the day and very cool during the night, whereas the vineyards that lie westward toward the ocean enjoy a mild and moderate climate. Coupled with soils that run the gamut from ancient beach and diatomaceous earth to chert and limestone, this is a near-perfect place for a wide variety of wine grape varieties.
