Chalk Hill, a sub-appellation of the American Viticultural Area (AVA) located in the northern part of Sonoma County, California, is renowned for its unique soils and exceptional climate. This AVA derives its name from the distinctive chalky hills that characterise the landscape and influence the region's terroir. The volcanic soil, coupled with excellent drainage and optimal sun exposure, creates ideal conditions for viticulture.
Chalk Hill wines are particularly noted for their elegant and structured Chardonnays, as well as their complex and refined Cabernet Sauvignons. Producers in this region often employ modern and innovative viticultural techniques to maximise the quality of their wines.
