Oak Knoll District Wineries
About Oak Knoll District
Oak Knoll District bridges the gap between cool Carneros and warmer upper Napa. Its wineries include Napa pioneers like Trefethen Family Vineyards, and the proximity to downtown Napa makes it easy to combine wine tasting with the city's restaurants and shops.
Oak Knoll District sits in the southern part of Napa Valley, just north of the city of Napa. The AVA was established in 2004, recognized for its cooler climate due to afternoon breezes from San Pablo Bay that moderate temperatures.
The district's benchland soils and moderate climate make it ideal for a range of varieties. Cabernet Sauvignon and Merlot thrive on the warmer western bench, while Chardonnay and Riesling excel in the cooler eastern areas.

St. Helena
St. Helena is Napa Valley's wine history in concentrated form — home to the oldest continuously operating winery (Beringer, 1876) and California's first tasting room (Charles Krug, 1861). Main Street's walkable mix of tasting rooms, restaurants, and the Culinary Institute of America at Greystone makes it the cultural heart of upper Napa.
Rutherford
Rutherford is the birthplace of the 'Rutherford Dust' concept — a distinctively earthy, cocoa-like tannin quality in Cabernet Sauvignon coined by legendary winemaker Andre Tchelistcheff. Home to some of Napa's most historically significant estates including Inglenook (1881) and Beaulieu Vineyard (1900).
Calistoga
Calistoga is the only Napa Valley town where world-class wine tasting meets natural hot springs, mud baths, and a geyser — all within a few miles. Its volcanic soils and mountain-ringed microclimate produce some of Napa's most bold and concentrated red wines.
Oakville
Oakville sits at the crossroads of Napa Valley's most important wine influences — warm enough for powerful Cabernet Sauvignon but cooled enough by bay fog for remarkable finesse. It is home to the legendary To Kalon vineyard (established 1868) and some of Napa's most iconic producers.
