The state in the central southwest of the USA with the capital Oklahoma City was explored early by the French and Spanish. From 1830 it was an Indian reservation, was opened to the white population in 1889 and became a federal state only in 1907. In the south, Texas joins, in the west New Mexico and in the east Missouri and Arkansas. The only AVA area Ozark Mountain is shared with the states of Arkansas and Missouri. Viticulture has only developed here in the last two decades. European vines and French hybrids are represented. A dozen production plants are spread across the country. The most important are Canadian River Vineyards & Winery, Cimarron Cellars Winery & Vineyards, Natura Vineyards & Winery, Nuyaka Creek Winery, Sparks Vineyard and Winery, Stone Bluff Cellars and Turkey Creek Vineyards.
