Jim Beam Jacob's Ghost® White Whiskey. Since 1795. Clear distilled. Clear filtered. 750 ml. 40% alc/vol. (80 proof). Aged 1 year minimum. Jacob's Ghost® celebrates the 'spirit' of Jim Beam's founding distiller, Jacob Beam - by refining the clear whiskey he first distilled in 1795. Jacob's Ghost® is clear, but it isn't moonshine or un-aged white dog. It's a special whiskey, aged at least one year in white oak barrels and crafted by our master distillers with over 200 years of Beam tradition to be uniquely versatile and flavorful.
