I am looking for information on a bottle of Booker's I purchased quite a few years ago. According to the Beam website, Bookers was first produced in 1988 as Booker's True Barrel. My bottle lot number is C-8-16-79, no. 05372. Does anyone know if this refers to a date or is it just a number? I'm sure this bottle was purchased before 1988. Any help would be greatly appreciated!
