Arkenstone

Arkenstone is a high-elevation Howell Mountain estate producing some of Napa Valley's most compelling cool-climate Cabernet Sauvignon and Sauvignon Blanc. Farming on steep volcanic soils above the fog line, the wines carry a tension and minerality that sets them apart from valley-floor Napa. Their Sauvignon Blanc program — including the celebrated Obsidian — has earned a devoted following and rivals the reds in ambition. Tastings are appointment-only and intentionally intimate, making a visit feel genuinely special.
