In his cellar, liquor maker and bar owner Gaspare Campari (1828-1882) developed all kinds of brews, among which tonic against fever, worms and cholera. His most successful brew was Bitter all’uso d’Olanda. After his death his son Davide sold the cafe and concentrated on the production of the beverage, which was patented as Campari in 1892. This beverage contains almost 70 herbs. Crushed, dried ‘cochenilles’ (lice) give Campari its typical red colour.
