Ron Abuelo is produced entirely from estate-grown sugar cane in Panama by the family-owned Varela Hermanos. The company dates back to 1908 when Don José Varela established the first sugar mill in the recently-formed Republic of Panama, the San Isidro Sugar Mill. Currently run by the third generation, Varela Hermanos has approximately 1000 hectares of land devoted exclusively to the cultivation of sugar cane.
