Farming the Extremes

Farming the Extremes

In 1973, we planted Poseidon Vineyard on what had been grazing land since the time of the missionaries. We 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 Wine Co. We seek and farm the extremes of the North Coast. This is our story

Where Vineyard Meets Bay

Where Vineyard Meets Bay

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 our vines.

Collaboration - Matching Oak and Wine

Collaboration - Matching Oak and Wine

We exclusively use barrels made from tight-grained Tokaj oak by Kádár Hungary, the cooperage we 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.

A Balanced Approach

A Balanced Approach

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

Made in small volumes, Poseidon Vineyard wines are available
through our wine club or at our tasting room.
