CASTILLO
Developed over five generations, Castillo is the most common coffee variety grown in Colombia.
Carefully created for its resistance to leaf rust, Castillo is a hybrid variety that now makes up 40% of Colombia’s coffee crops. It is a “dwarfed” tree that can be planted in high density, resulting in generous crop yields.
That being said, some in the specialty coffee sector consider Castillo to be lower quality than other varieties as it shares a genetic heritage with robusta beans.
Before Castillo was introduced, Caturra was the most widely found coffee variety in Colombia. However, Caturra plants are highly susceptible to coffee leaf rust, also known as la Roya. Coffee leaf rust prevents plants from photosynthesising, which can quickly kill the entire tree and may reduce crop yield by up to 70% in severe cases.
In 1938, Colombia established the National Coffee Research Centre called Cenicafé. Researchers worked to improve the genetics in Colombian coffee to help with productivity and disease resistance in crops.
Named after researcher Jamie Castillo, the Castillo coffee variety was released for production in 2005. It is the result of the successful hybridisation of Caturra with the Timor Hybrid.
So far, seven additional cultivars have been developed from Castillo, each trying to retain the cup quality of Cattura and the disease resistance from the Timor Hybrid.
