Hewitt Vineyard

Hewitt Vineyard is the purest expression of single-vineyard, single-varietal winemaking in Rutherford, an estate that produces one wine from one vineyard in one appellation: Cabernet Sauvignon from Rutherford, made by Thomas Rivers Brown. Founded in 2001 by William Hewitt (the family behind Provenance Vineyards), the project distills the Rutherford terroir into its most elemental form. There is no second wine, no white wine, and no blending grape. Just 34 acres of Rutherford Cabernet and one of the most talented winemakers in the valley.

The 34-acre vineyard sits on the Rutherford benchland, where the deep, well-drained alluvial soils have been producing some of Napa Valley's most acclaimed Cabernets for over a century. The site benefits from the appellation's characteristic warmth, moderated by cooling influences from the adjacent western hills. The farming is meticulous, with each block managed individually and harvested at the precise moment of optimal ripeness. The singular focus on one vineyard and one variety allows the winemaking team to devote total attention to the site's expression.

Thomas Rivers Brown makes the Hewitt Cabernet with the same intensity and precision he brings to his 30-plus other clients, but the simplicity of the project, one vineyard, one wine, gives him a clarity of purpose that more complex portfolios cannot provide. The wine is classic Rutherford: dark-fruited, earthy, structured, with the mineral quality that locals call "Rutherford Dust." The winemaking is confident and unhurried, with extended maceration, aging in new French oak, and a patience that allows each vintage to find its natural balance.

Tastings of Hewitt wines are by appointment and take place on the Rutherford estate, where the single-vineyard concept is reinforced by the sight of the 34 acres that produce every drop in the glass. The experience is focused and educational, with the tasting host explaining how the Rutherford terroir shapes the wine's character and how each vintage expresses the site differently. The $90 fee reflects the single-vineyard exclusivity and the quality of what is poured.

Hewitt's importance lies in its discipline. In a valley where most producers hedge their bets with diverse portfolios and multiple vineyard sources, Hewitt bets everything on 34 acres and one variety. The gamble works because the vineyard is exceptional and the winemaker is world-class, but the courage required to produce a single wine from a single site should not be underestimated. For visitors who want to understand what Rutherford Cabernet tastes like at its purest, Hewitt is the definitive answer.
