The UNESCO Memory of the World Programme's Regional Committee for Latin America and the Caribbean has added documents to its Register that confirm the Peruvian origin of pisco, based on manuscripts from 1587 and 1613. However, Chile's Minister of Agriculture, Esteban Valenzuela, has stirred controversy by asserting that Chile shares the drink's origin and accused Peruvians of being obstinate for protecting their culture. Peruvian journalist and writer Ítalo Sifuentes has refuted Valenzuela's claims, providing evidence of the drink's Peruvian history and the earliest record of the word 'pisco' dating back to 1450.
