Outpost Wines

Outpost Wines is one of the highest-altitude wineries in Napa Valley, a Howell Mountain estate at 2,200 feet that produces wines of extraordinary intensity from volcanic soils and extreme growing conditions. Founded in 1998 by Frank Dotzler, the estate takes its name from its remote, outpost-like position on the mountain's upper reaches, where the thin air, intense sunlight, and wide temperature swings create conditions that push vines to their limits and produce fruit of corresponding concentration. Thomas Rivers Brown, the valley's most prolific consulting winemaker, crafts the wines.

The 30-acre vineyard sits on volcanic soils composed of red clay and fractured rock, at an elevation where the fog never reaches and the sun beats down with relentless intensity. The extreme altitude produces small berries with thick skins, concentrating flavors, tannins, and color to levels that valley-floor vineyards cannot approach. The vineyard is planted to Cabernet Sauvignon, Zinfandel, Petite Sirah, and Grenache, with each variety occupying the soil type and exposure best suited to its needs. The diversity of the planting at this extreme elevation is itself unusual and reflects the estate's willingness to experiment with the mountain's potential.

Thomas Rivers Brown produces wines that capture the mountain's intensity without sacrificing balance or drinkability. The estate Cabernet Sauvignon is powerful and dark, with the volcanic minerality and firm tannins that mark it as unmistakably mountain-grown. The Zinfandel, from some of the highest Zinfandel vines in the valley, shows a structure and complexity that challenges the variety's reputation as a simple, fruity wine. The Petite Sirah is inky and bold, and the Grenache provides a surprisingly elegant counterpoint to the bigger reds.

Tastings at Outpost are by appointment and require the drive to the upper reaches of Howell Mountain, an experience that filters out casual visitors and rewards the committed with one of the most dramatic vineyard settings in the valley. The tasting room is modest and mountain-rustic, with the views providing all the architectural drama necessary. The wines are poured generously, and the staff share the geological and viticultural story of the mountaintop site. At $75, the tasting reflects the quality and the exclusivity of the location.

Outpost demonstrates what happens when vines are pushed to their physiological limits. The extreme altitude, intense sun, and rocky soils create conditions that would kill lesser plants, but the surviving vines produce fruit of astonishing concentration and complexity. The wines are not subtle, but they are genuine, capturing the wild, untamed character of the mountain in every glass.
