American White Oak stretches from Texas to Maine, and from Minnesota to Florida, as well as reaching across borders into Canada and Mexico. American oak barrel-making was oriented primarily to bourbon and whiskey distilleries until the early 1980s, when American-produced oak barrels began to be used for winemaking. Over the last two decades the quality of these barrels has improved radically. Following Prohibition, and until the early 1980s, some whiskey barrels were adapted to wine production by steam bending and not charring the barrel interior. In the early 1980s, Nadalié USA developed seasoning and production techniques for American oak that other cooperages would quickly adopt, leading the accelerated evolution of the American-made wine barrel.
