Horse Heaven Hills AVA
Situated 15 miles west of the small town of Patterson, Washington, Alder Ridge sits atop a series of arid, sparsely vegetated ridges that shoot up nearly 1,000 feet above the great Columbia River below. This hot landscape receives an average of just 5 inches of rain each year, and it’s precisely this climate and the steep south-facing slopes that make Alder Ridge the perfect spot for growing high-quality grapes. The region received Horse Heaven Hills AVA certification in August 2005 and is now one of the most prestigious grape-growing regions in Washington.
