Welcome to O'Shaughnessy

O’Shaughnessy Estate Winery sits at 1,800 feet on the heralded Howell Mountain appellation in the beautiful Napa Valley.  Founded in 1996, the estate encompasses one hundred and twenty acres.

Winemaker Sean Capiaux has overseen the planting of the vineyard and selected numerous clones of Cabernet Sauvignon and all seven of the historic Bordeaux varietals for this unique property.

O’Shaughnessy Estate Winery uses modern equipment to produce non-interventionist wines that are naturally fermented and bottled unfined and unfiltered. These techniques allow the varietal character and terroir of O’Shaughnessy Estate vineyards to be the stars of the show.
