Old Forester will release the 21th iteration of its limited-edition, vintage-dated Birthday Bourbon on Sept. 2 in celebration of founder George Garvin Brown’s birthday. This year marks the 151st year of the company he began in 1870.

The 2021 Birthday Bourbon will be bottled at 104 proof and was barreled in 2009. After showing exceptionally unique character during a tasting panel, the barrels were chosen specifically for this year’s Birthday Bourbon. The full allotment of the product represents one day’s production of Old Forester.
