Award-winning mixologist Salvatore Calabrese created this £5,500 (around $6,600) cocktail by combining Clos de Griffier Vieux cognac from 1788, Kummel liqueur from 1770, orange liqueur from 1860, and Angostura bitters from 1930. Salvatore's Legacy is like drinking years of history in a glass — but of course, it will cost you.
