In 2016, Jack Daniel’s announced the company would make changes to its official history. They planned to honor Nathan “Nearest” Green, the African American man who taught the real Jack Daniel to make whiskey in the mid-1800s. Green had been enslaved on the farm of a preacher and distiller named Dan Call; Jack Daniel, 30 years younger than Green, was a chore boy on the same farm. It fell on Green to teach Daniel how to work the still and use a charcoal filtration process that likely originated in West Africa.
