Poseidon Vineyard & Obsidian Ridge

  • 23568 Arnold Drive, Sonoma

We are producers of single-vineyard wines from Carneros, Napa and the high Mayacamas Mountains. We own and farm our vineyards; Posedion Vineyard at sea level and Obsidian Ridge Vineyard at elevation 2,640'. We build our own barrels with oak selected from the forests of
Tokaj, Hungary. We craft our wines in small batches, which is critical to our winemaking philosophy. Our tasting room is now open at Cornerstone Sonoma.
