In 1845, the son of Don Salvador added a corn mill operation to the profitable fruit and vegetable production. Later, Don Salvador's grandson oversaw the addition of coffee growing and processing to the plantains and cornmeal, taking advantage of the great coffee-growing boom of the 1880s and 1890s. Don Salvador's son and grandson introduced some of the most innovative farm machinery on the island, powered by a nearby waterfall. Eventually Hacienda Buena Vista would become one of the most successful plantations in the mountains of Puerto Rico.
