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.

The 2,400-foot Sonoma Mountain range begins to rise above the town of Glen Ellen at the western edge of the Valley of the Moon. Found here are high-altitude, steep-sloped vineyards, with eastern exposures to catch the fog-free morning sun. These vineyards fall within the larger Sonoma Valley AVA. However, due to the unique hillside terroir, they are entitled to use the more specific designation of the Sonoma Mountain AVA. Powerful, yet elegant Cabernet Sauvignons – the appellation’s specialty – grow here on well-drained soils. The irregular folds and crevices of the mountain slopes also create microclimates suitable for limited production of a diverse range of other varieties, including Chardonnay, Sauvignon Blanc, Semillon, as well as Pinot Noir and Zinfandel.  More Info.
