An appellation is a geographical area recognized for a distinctive combination of soil, climate, and identifiable regional wine character. The word appellation comes from the French Appellation d'Origine Controlee laws, which are laws meant to ensure quality within specific regions of France. These same principles have been used to create American Viticultural Areas (AVA) in the United States.

Appellations

Oak Knoll Appellation (AVA)

Oak Knoll Appellation Climate: Moderately warm, with temperatures commonly in the mid-90°F (34-35.5°C) range in high summer, but also still strongly affected by night and early morning fog which helps keep acidity levels good. East side of the AVA receives more of warmer afternoon sun.

Elevation: 75 to 500 ft (23 to 150m).

Rainfall: 35 inches (87.5cm) annually.

Oak Knoll Soils: Primarily sedimentary gravelly alluvial loams on the western side, with more volcanic but heavier soils on the eastern side. Low to moderate fertility and fairly deep, with average water retention. More Info.
