The 2020 Old Forester Birthday Bourbon is aged 10 years, and barreled on June 5, 2010. This year’s offering was bottled at 98 proof – determined to be where it tastes best according to Master Distiller Chris Morris and Master Taster Jackie Zykan. This is the fourth Birthday Bourbon vintage to be bottled at the new Old Forester Distilling Co. on Louisville's Historic Whiskey Row.
