In 1836, George Calvert Yount, one of the Valley’s earliest settlers, was granted his Rancho Caymus. He soon planted the first vineyard just outside the town that now bears his name. Since then, vineyards have always existed in the appellation. Today, the wines of Yountville are known internationally. Great wine houses reside here and continue a proud heritage of winegrowing. Many people rank Yountville wines among the very best of Napa Valley. The AVA has one of the valley’s coolest vineyard exposures. Its long, chilly growing season produces incredibly long-lived Cabernet Sauvignon, with rock-hard tannins and deep concentration. Just over 8,000 acres in area, nearly half of this appellation is under vine.
