Already in the 16th century, Spanish settlers in Chile and Peru began producing aguardiente[14][15] distilled from fermented grapes.[16] Since at least 1764, Peruvian aguardiente was called "pisco" after its port of shipping;[4][12] the usage of the name "pisco" for aguardiente then spread to Chile.[upper-alpha 3] The right to produce and market pisco, still made in Peru and Chile, is the subject of ongoing disputes between the two countries.[17]
