Cerro San Luis Micromill is a family business run by two siblings and their spouses. The family's farms are adjacent to one another, but the plots are given separate names for lot separation purposes. The mill is located at the family home, just a few miles away.
In the interest of improving their quality and remaining competitive, they have focused on growing different varieties, and about 4 years ago they replaced their older stock with 10 or more different types of coffee, including Caturra, Red and Orange Bourbon, SL-28, Catuai, Villa Sarchi, and Maragogype.
After harvesting, the cherry is brought right to the family home, where they are able to do a variety of different processes, from washed and honeys to natural. As is common at mills in Costa Rica, at Cerro San Luis the type of honey is decided by how much mucilage is left on the coffee after depulping.
