Old Forester will release the 21st 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 is made up of 119 barrels, aged 12 years, and barreled on April 16, 2009. After showing exceptionally unique character during a tasting panel, the 12-year-old barrels were chosen specifically for this year’s Birthday Bourbon.
