Howell Mountain • Mt. Veeder • Oakville

Three appellations. One family. Wines built to last.

O'Shaughnessy Estate Winery • Since 1990

Rooted in Howell Mountain

Since 1990, O’Shaughnessy Estate Winery has cultivated exceptional vineyards across Napa Valley. Our Howell Mountain estate has exemplified our commitment to organic farming, precision viticulture, and uncompromising quality. Today, our wines reflect the depth, elegance, and enduring character of fruit grown across three of Napa Valley’s most distinguished appellations.

Four Estate Vineyards • Three Appellations

A sense of place.

Howell Mountain

Estate vineyards at 1800 feet produce small clusters, concentrated fruit, and wines with the firm structure and intensity this mountain is known for.

Mt. Veeder

Two vineyards, one mountain – steeply terraced east-facing and land on the southern ridge. Different exposures, but both forcing the vines to work for everything.

Oakville

Thirty acres in Oakville, home to our white wines, where young alluvial soils and a temperate growing climate produce wines of remarkable balance, elegance, and site expression.

Farming first.
Everything else follows.

“These vineyards have a character that doesn’t need to be invented.
My job is to not obscure it.”
