Casas de Hualdo oil comes from the Casas de Hualdo oil mill, founded by Francisco Riberas in 1986. This oil mill located it in El Carpio de Tajo in Toledo and little by little it has been expanding its olive grove.

El Carpio de Tajo is located in a natural enclave of incalculable value for its wealth of fauna and flora. On the banks of the Tagus River, where wildlife is in perfect balance with agriculture. This is the reason why Casas de Hualdo gives priority to sustainability with the natural environment.
