The new settlers dedicated themselves to the cultivation of these crops and within a short period of time some began to save enough money to own and operate their own grocery stores. Coffee was the means by which some made their fortunes. Cultivation of coffee in Yauco originally began in the Rancheras and Diego Hernández sectors, and later extended to the Aguas Blancas, Frailes and Rubias sectors. By the 1860s the Corsican settlers were the leaders of the coffee industry in Puerto Rico: seven out of ten coffee plantations were owned by Corsicans.
