La Felsina is named for the city where the Zanotti-Cavazzoni family was born. The Etruscans, a people who once lived in Italy's Tuscany, founded the town of Felsina, which is now known as Bologna. The Two Towers are this city's historical icons: Asinelli is the highest, and Garisenda is the steepest, similar to the famous Pisa Tower. As a result, the Garisenda tower-like sugar cane that serves as the La Felsina sugar mill's logo was created.
In 1932, three members of the Zanotti-Cavazzoni family—Alfeo, Amedeo, and Ulrrico—acquired a rice factory in the city of Guarambaré and incorporated the production of sugar, alcohol, cane, and coconut oil into La Felsina Agricola Comercial e Industrial Sociedad Anónima (A.I.C.S.A., for its Spanish acronym).
La Felsina has played a significant role not only in Paraguay's economic development but also in Paraguay's history since its inception. La Felsina produced coconut charcoal for use in gas masks during the Chaco War, ensuring the safety of Paraguayan soldiers.
