Angwin is a census-designated place in Napa County, California, best known as the site of Pacific Union College, and part of the northern San Francisco Bay Area. The population was 3,051 at the 2010 census.
Angwin sits just below the summit of Howell Mountain. Rising to the east of Napa Valley, Howell Mountain is one of the most storied wine-growing appellations in the world. Above the Valley fog, it drenches grapes in sun and cool mountain air, and its rocky soil forces the vines to root deeply in search of water. This combination creates the amazingly intense, complex flavors for which Howell Mountain wines are famous. At about 1800 feet, the tiny town of Angwin sits astride a single crossroad, home to a small shopping center on one side and the campus of Pacific Union College on the other. Though there's not a single restaurant or hotel here, wineries in Angwin are plentiful and well worth the climb up The Hill, as the locals call it. For a classic wine-tasting experience and views that stretch from St. Helena to Calistoga, stop by Burgess Cellars. At the lower edge of Angwin, Cade offers highly rated wines in a state-of-the-art, environmentally friendly winery with a strikingly modern design.
