A rugged, isolated sub-valley within the Rogue Valley where the Applegate River drains north through the Siskiyou Mountains, distinguished by the presence of serpentine and ultramafic soils found almost nowhere else in American viticulture. These magnesium-rich, nutrient-poor soils stress vines severely and concentrate flavours; Troon Vineyard's work in biodynamic viticulture on serpentine has produced some of the most compelling and unusual wines in the Pacific Northwest. Tempranillo, syrah, merlot, and cabernet achieve depth and structural interest unavailable on more conventional soils.
