The Ozark Mountain AVA is an American Viticultural Area located in northwest Arkansas, southern Missouri, and northeast Oklahoma. The sixth largest American Viticultural Area in total size, Ozark Mountain AVA covers 3520000acres. Four smaller AVAs have been established within its boundaries, to recognize those distinct regions whose climate, vineyard soil, or other growing conditions create unique areas for viticulture.[4] The hardiness zone in the region varies from 6a to 7b.[5]
