El Cuarenteño is a rural community located in the foothills of Sierra de San Juan, just west of Tepic. The area was initially settled in 1910, established as the center of a wealthy landowner’s farm. Several years later, the owner received petitions from his workers wanting to buy pieces of his land, but he declined their offer preferring instead to lease the property. In 1939 the Mexican government passed an agrarian reform resolution allowing the formation of Ejidos. The following year the community of El Cuarenteño was granted an endowment of 3,500 hectares to form their own Ejido. Currently they have about 840 hectares of coffee in production at altitudes between 900 and 1400 meters above sea level.
