This decision led Justus and her family to seek permission to join their family name with that of the McCoys and establish a moonshine distillery. After receiving permission from the state of West Virginia's legal channels in 2014, Justus's efforts began to take shape and construction on a moonshine distillery soon began along James Avenue in the small town of Gilbert, located in Mingo County, West Virginia, on original Hatfield land, in the center of the events of the Hatfield and McCoy feud, in a converted garage just six miles from Devil Anse's gravesite. The renovation of the garage was finished in January of 2015, and later that same month the Hatfield & McCoy Moonshine Distillery opened to the public, taking on the motto Drink of the Devil in honor of Devil Anse, the man whose process and recipe they used.
The business is run primarily by Justus and her daughter with production taking place under the watch of her son-in-law. Another key figure in the production of the product is Ronald McCoy, the great-great grandson and oldest living descendant of Randolph McCoy, who served as the initial consultant for the business's startup and the product's testing and advertisement. The moonshine produced by the business is made from corn grain and alcohol which undergoes both fermentation and distillation at Hatfield & McCoy Moonshine. Bottles of the product are also corked and packaged at the site before later being shipped to Florida, Kentucky, New Jersey, Virginia, and Pennsylvania as well as other locations in West Virginia. Local customers also buy the product directly at the business, where orders are taken at the bar near the front entrance.
