Old Forester 1897 Bottled in Bond is crafted to honor a watershed moment in bourbon history – the U.S. Bottled-in-Bond Act of 1897. This expression follows the Bottled in Bond standards that whisky must be aged in a federally bonded warehouse for at least four years, the product of one distillation season, one distiller and from one distillery and bottled at 100 Proof. The concept behind these regulations – the idea of ‘sealed in quality’ – was something Old Forester introduced in 1870, as America’s First Bottled Bourbon.
