Old Fitzgerald is a brand of wheated bourbon distilled in Louisville, Kentucky, by Heaven Hill Distilleries, Inc. Old Fitzgerald was first produced in 1870 for rail and steamship lines and private clubs located primarily in the south by John E. Fitzgerald in Frankfort, Kentucky.

[1] Around 1900, "Old Fitz" was released to the public in America and Europe.

During the Prohibition in the United States, Old Fitzgerald was one of a select few to distill under government supervision for the national medicinal trade, it was soon after acquired by Pappy Van Winkle for $10,000 who then introduced the "Whisper of Wheat" to the original recipe.

By substituting some wheat for the more traditional rye in the grain recipe, Old Fitzgerald presented a rounder, softer profile than other bourbons.

[2] In 1999, Diageo sold the brand, along with the Bernheim Distillery, to Heaven Hill, which currently produces and markets Old Fitzgerald.
