The Castillo Variety is a coffee variety developed in Colombia as a response to the challenges related to the diseases that affect coffee crops, in particular coffee rust. It was created by the National Federation of Coffee Growers of Colombia through a research and genetic improvement program.

The Castillo variety is the result of the crossing of the Caturra and Timor varieties and is characterized as being resistant to coffee rust and other diseases that can damage coffee crops. Rust is a fungal disease that can cause great losses in coffee plantations, for which reason the development of a resistant variety was a significant advance for the Colombian coffee industry.

It is characterized by its high production and resistance to rust and therefore does not require the application of fungicides, which can damage the environment and increase the cost of production for farmers.

In addition to its resistance to diseases, the coffee trees of the Castillo variety have good production and cup quality.

Castillo coffee beans generally have a balanced and pleasant flavor profile, with notes that can include caramel, chocolate, nuts, and fruits. In blind tests and other sensory evaluations, it was discovered that it can have similar qualities to Typica, Caturra, and Bourbon.

It is a versatile variety that is used to prepare a variety of coffee styles, from espresso to filtered coffee.
