Oak Knoll District

The most vineyards planted in a sub-region in all of Napa Valley – the quiet workhorse of Napa Valley wine.


Wines to know in Oak Knoll District

In the widest part of the valley, sitting directly north of the city of Napa sits Oak Knoll District. This region is the workhorse of Napa Valley wine with the most vineyard area.

The most important grapes in the area are Cabernet Sauvignon, Chardonnay, and Merlot.

The bay cloud cover keeps Oak Knoll cool during the day which allows Cabernet Sauvignon to have a long hang time. Red wines from Oak Knoll still have great tannin and structure as with all of the Napa Valley, but often with more delicate herbal and floral aromas.
