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, opened to the white population in 1889 and only became a federal state in 1907. It is bordered by Texas to the south, New Mexico to the west and Missouri and Arkansas to the east. 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 farms 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.
