Today mimicking this historic bottling, this unique expression of Old Forester has undergone a second barreling, granting it exceptional character, a smooth and sweet flavor and a clean, crisp finish. Entering the second barrel at a low 100 proof allows more of the sweet wood sugars to dissolve into the whiskey. 1910 Old Fine Whiskey is the fourth and final expression of the Whiskey Row Series, presented at 93 proof.
