Aperitivo Bitter Liqueurs

Campari, Aperol and the red-and-orange bitters of the Italian aperitivo hour: where they came from and how they drink.

Level 23 min readUpdated October 2026 Liqueur aperitivo shelf

In one sip

Aperitivo bitters are the bright end of the bitter family: red or orange, bittersweet, and designed to be drunk before dinner with soda, sparkling wine or vermouth. The red style meets sweet vermouth in the Americano and the Negroni. The orange style is lower in alcohol and mellower, and its signature drink is the spritz.

Where it started

Campari's own timeline dates the recipe to 1860, when Gaspare Campari created it, and says it has not been altered since.1 In 1867 he moved into Milan's new Galleria Vittorio Emanuele II and opened Caffè Campari; by 1904 demand had moved production to a plant in Sesto San Giovanni; and in 1915 his son Davide opened the Camparino bar in the Galleria.1

Aperol came later and from Padua. The Barbieri company was founded there in 1891, and Giuseppe Barbieri's sons Luigi and Silvio created Aperol in 1919 for the Padua International Fair.2 Difford's notes that the idea of an 11 percent aperitif did not take off until after the Second World War, and that Gruppo Campari has owned the brand since 2003.2

The cocktails followed. The Milano-Torino paired Campari from Milan with sweet vermouth from Turin; add soda and it becomes the Americano.3 The usual Negroni story puts Count Camillo Negroni at a Florence bar in 1919, asking for gin in place of the soda.3 Campari's own timeline simply places the Americano and the Negroni at the start of the 1920s.1 Both versions are stories; neither is a document.

Where and how it's made

These are infusions: bitter roots, barks, peels and herbs steeped in neutral spirit, sweetened, and colored. Aperol's flavor and orange color come from a secret infusion of 16 ingredients, among them bitter orange, gentian, cinchona and rhubarb, and it is bottled without aging.2

In EU law a red bitter can be a liqueur (15 percent and up, with a sweetening floor) or a "bitter-tasting spirit drink", also with a 15 percent minimum and a predominantly bitter taste.4 Aperol, at 11 percent, sits well below that floor.2 A separate EU family covers wine-based bitters: "bitter vino" is an aromatised wine flavored mainly with gentian, and "bitter soda" is a bitter vino drink topped with carbonated water at 8 to under 10.5 percent alcohol.5

How to taste it

Taste a splash neat first to learn the bitterness, then as it is meant to be drunk: over ice with soda, or with sparkling wine and a slice of orange. Look for citrus pith, rhubarb and gentian. Pairings: potato chips, green olives, salty cured meats.
