The largest of the Nazca vineyards were located in the rich Ingenio Valley, and were property of the Society of Jesus, Jesuit missionaries and priests. The hacienda San Joseph de la Nasca, located in the upper part of the middle Ingenio Valley, was owned by the Jesuit College of Cuzco. San Francisco Xavier de la Nasca, in the lower part of the middle valley, was owned by the Jesuit College of San Pablo in Lima. Both of these estates used numerous workers who were enslaved persons of sub-Saharan African descent. In addition to producing wines and brandies, both estates had substantial infrastructure for producing the ceramic storage jars, known as "botijas," in which the wine and brandy was transported.
