The volcanic range, known as the Nine Sisters, helped create the soil found in the valley. This volcanic range starts with Morro Rock in the northwest, and ends with Islay Hill in the southeast. Much of the valley was once part of the Pacific Ocean and ancient marine sediments have left a fertile base of calcareous shale and course sand. The soil is further enriched with dark humus, loam and clay. The Edna Valley appellation has one of California’s longest growing seasons. The extended growing season gives complex flavors to the grapes, with more balance in terms of sugars and acidity. The cool growing conditions result in traditionally very low yielding crops.
