The Rocks District
Columbia Valley
One of the most geologically distinctive wine regions anywhere: a cobblestone-covered alluvial fan where vines root through river rocks into basalt below. The heat-retaining stones and unique terroir produce Syrah of extraordinary depth and mineral intensity.
The wines of The Rocks District are made primarily from Syrah, Cabernet Sauvignon, Merlot and other Columbia Valley varieties.

Climate
The cobblestone surface creates a unique heat island effect, absorbing and radiating warmth that extends the growing season and produces notably riper fruit than surrounding areas. The stones also reflect light upward to grape clusters while the excellent drainage keeps the site naturally dry despite proximity to the Columbia River.
Terroir
The Rocks District sits atop the Missoula Flood deposits from 15,000 years ago, where Columbia River basalt bedrock is overlain by massive cobblestones and alluvial sediments. This fractured basalt basement provides excellent drainage while forcing vine roots deep into mineral-rich cracks and fissures, with the rocky surface layer creating a natural heat sink that moderates soil temperatures.
