Poseidon Vineyard Estate

In 1973, Poseidon Vineyard was planted on what had been grazing land since the time of the missionaries. They were among the first to farm the southern extreme of Napa Carneros, which at the time was considered too cool to ripen wine grapes. Poseidon Vineyard is the heritage wine project of Obsidian Ridge, where the idea was to seek out and farm the extremes of the North Coast.

Poseidon Vineyard lies at the confluence of Carneros Creek and the Napa River. At high tide the river tastes of salt, a reminder of the sea’s proximity. Pacific wind brings fog and cooler temperatures to balance the intensity of the California sun, while clay and gravel soil provide ideal drainage for the vines. They exclusively use barrels made from tight-grained Tokaj oak by Kádár Hungary, the cooperage they have owned for three decades. This is one of a handful of places in the world where Quercus Petraea, an oak species highly prized for its enticing aromas and subtle oak influence, is grown.

Through four decades of growing, three decades of coopering, and two decades of winemaking, Obsidian Ridge have created their own unique expressions of California Chardonnay and Pinot Noir.
