Tempus Fugit Gran Classico Bitter is a bitter apéritif liqueur created following the "Italian Bitter of Turin" recipe dating from the 1860s. It is made from a maceration of 25 aromatic herbs and roots including wormwood, gentian, bitter orange peel, rhubarb, and hyssop. The maceration also creates a naturally attractive, golden-amber color, and no additional coloring is added.
