About Willett Pot Still Reserve Bourbon is produced in Bardstown, Kentucky. It is a Kentucky straight bourbon whiskey bottled at 47% abv, with 8–10 year aging. Tasting Notes Nose is "vanilla lemon cake." The palate is a balance of caramel, vanilla, spices and citrus. I'm not sure if they made the opulent bottle to match the Whiskey or vice versa.
