Our Terroir- The Dry Creek Valley Located in the heart of Northern Sonoma, the Dry Creek Valley is characterized by warm days, cool nights and a long and balanced growing season. In the evening, cool marine influences enter from the southern portion of the valley where the Dry Creek flows into the Russian River. This terroir produces wines of such exceptional quality that the Dry Creek Valley has been considered by many to be one of the finest sources of Zinfandel in California.
