The Horse Heaven Hills AVA, established in 2005, is a prominent wine-growing region in southeastern Washington State, bordered by the Yakima Valley to the north and the Columbia River to the south. This area is renowned for its unique combination of climatic and geological conditions favorable for viticulture. The south-facing slopes benefit from consistent sunshine, while the Columbia River moderates temperatures, reducing frost risks and extending the growing season. Steady winds from the river decrease disease pressure and encourage the development of grape skins, contributing to the structure and complexity of the wines. The soils are predominantly sandy and well-draining, formed from ancient lava flows and glacial floods, allowing vines to establish deep root systems. These factors collectively create an environment conducive to producing high-quality grapes, particularly Bordeaux varietals like Merlot and Cabernet Sauvignon. Wines from Horse Heaven Hills are characterized by their elegance, balance, and depth of flavor, reflecting the distinctive terroir of the region.
