Santa Isabel farm was founded in 1889 by Federico and Isabel Keller, who from the beginning sought to integrate the farm with its natural surroundings. This philosophy hasn’t wavered over the years and has led the farm to be declared a Private Natural Reserve within the Guatemala System of Protected Areas. The farm was certified Rainforest Alliance in 2004, and all inputs (fertilizer, pesticides) are certified organic. Because of this and other factors, Santa Isabel was hit hard by rust leaf disease (or la roya) in 2014. Only now has the farm started to come back online.
