Our Provenance philosophy focuses on the importance of discovering vineyards that show unique provenance-origin or source-that will define the quality and character of their wines. We reveal their terroir-soils, microclimates and exposures-as aromas, flavors and textures. Each Single Vineyard bottling expresses the character of a small planting of vines, while the Regional Exclusive wines demonstrate the unique appellations of Napa Valley, each recognized for distinctive terroir.
