Jack Daniel's 1915 was a very hectic & special year for Jack Daniel's. it was four years after Jack Daniel's had died, the world was at war & Tennessee was under prohibition. This was time when people begun to worry if Jack Daniel's would ever be the same again. however Mr Daniel's would not leave his famous distillery in the hands of no one. Mr Lem Motlow, Jack's nephew, was now in charge of the distillery & he did not change a thing from his uncle's way of making Tennessee whiskey. He continued to perform the charcoal mellowing exactly how his uncle wanted him to but he still came under fire from critics. Therefore Lem sent off his whiskey to the most prestigious testing body on of his day, the institute of hygiene in London & on the 17th of November 1915 his whiskey was deemed unaltered & worthy of the certificate of institute of hygiene. This stopped his critics as Jack Daniel's still had the same fantastic taste & style.
