A typical bottle of Old Forester Bourbon contains whiskey from a number of different years. But their Birthday Bourbon is actually vintage-dated, like a bottle of fine wine. In fact, the bourbon is all from one specific day of production, making this beverage impossible to duplicate. This year's model has flavors of creamy vanilla, cinnamon and orange peel. Old Forester is the only bourbon to be produced before, during and after Prohibition, but the Birthday Bourbon series didn't begin until 2002. The product celebrates the birthday of the dearly departed George Garvin Brown, the founder of Old Forester, the first man to bottle bourbon and the Brown of liquor giant "Brown-Forman." If not straight up: Some may call it sacrilegious, but mixing this bourbon into an Old Fashioned always makes for a good time.
