Delfina was a prosperous hacienda of approximately 1,500 cuerdas established ca. 1855 by Spanish immigrant from Catalonia Juan Jaime Amill Guash (1819-1895) and his wife Delfina Amill Oramas, hence the name Delfina.  In the Feria de Exposición de Ponce in 1882, coffee from Hacienda Delfina was recognized for its quality and in 1883 it won the Gold Medal. 

Due to the reduction in demand from established markets in Europe caused by WWI and the subsequent reduction in price, coffee producers had to look for other products.  Some were forced to stop producing coffee and surrender their land to creditors, which according to Luis Pumarada O'Neill, was the case with the Amill family who between 1916 and 1920 had to deed some of their properties to creditors in lieu of payment.  

It was around this time that Delfina was acquired by the Llinás family who owned the firm G. Llinás & Cia. and operated the Tahona Llinás in Yauco, a major coffee exporter in Puerto Rico.  Hacienda Delfina was the processing center for coffee harvested in the nearby Hacienda Candelaria and G. Llinás & Cia. other coffee haciendas in the region.
