(AP) — Jack Daniel’s is being served a $100 million-plus expansion of its rural Tennessee distillery to flex more muscle in the growing whiskey market.The investment amounts to the largest single production expansion in the brand’s long history. It will add stills and barrel warehouses at the Jack Daniel’s operations in Lynchburg, the brand’s Louisville-based parent company, Brown-Forman Corp., said Thursday.A second production building will go up on the same grounds as the current distillery site, which traces its roots back to a year after the Civil War ended.Expansion work will begin this fall and is expected to wrap up within two years. Company officials didn’t specify how many stills and warehouses where the whiskey ages will be added.
