Don Tiburcio Benegas (1844-1910) is regarded as a decisive initiator and winegrowing pioneer in Argentina
. In 1861 the old colonial city of Mendoza was almost completely destroyed by an earthquake. Benegas became the city's banker and sorted out the chaotic finances caused by the catastrophe. In 1870, he married Lubina Blanco and that was the beginning of his interest in viticulture. His father-in-law, Don Eusebios Blanco, was a landowner and in 1872 he had written the book "Las viñas y los vinos de Mendoza", the first fundamental work on Argentine viticulture. Benegas gave up his banking career and in 1883 bought a small plot of land in the neighbouring province of Godoy Cruz (now the province of San Vincente) and called it "El Trapiche".
