Old Forester will release the 20th iteration of its limited-edition, vintage-dated Birthday Bourbon on Wednesday, Sept. 2 in celebration of founder George Garvin Brown’s birthday. This year marks the 150th year of the company he began in 1870.

The 2020 Birthday Bourbon will be bottled at 98 proof and is made up of 95 barrels, aged 10 years, and barreled on June 5, 2010. After showing exceptionally unique character during a tasting panel, the 10-year-old barrels were chosen specifically for this year’s Birthday Bourbon. The full allotment of the product represents one day’s production of Old Forester.
