Negroni

The drink's origins are not known with certainty. The most widely reported account is that it was first mixed in Florence, Italy, in 1919, at Caffè Giacosa (then called Caffè Casoni), on Via de' Tornabuoni. (The Caffè no longer exists; the site is now occupied by a Giorgio Armani boutique.)

The commonly-held origin story is that it was concocted by a member of the Negroni family asking the bartender to strengthen the Americano by adding gin, rather than the normal soda water. The bartender also added an orange garnish rather than the typical lemon garnish of the Americano to signify that it was a different drink.
