Subsoil Wines
Over 20,000 years ago, the Missoula Floods carved through the Pacific Northwest, depositing rich layers of sediment that formed the subsoils of Washington’s Columbia Basin. From this ancient foundation, Subsoil wines emerge—bright, fruit-driven expressions of the Horse Heaven Hills crafted by the Mercer family’s generations of sustainable farming and winemaking expertise.
