Volcán Azul
We have bought coffee from Alejo Castro and his family’s farm, Volcán Azul. Alejo is a fifth-generation producer whose family has about 200 years in coffee. Our purchases from Alejo have included small, separately harvested and processed lots of Gesha, Caturra and H1, grown at about 1,500 to 1,700 meters above sea level.

Processing is a distinctive part of Alejo’s work. He experiments widely, and more than half of the farm’s production uses unusual methods. All the lots we have bought from him have been naturals, meaning the coffee dried inside the whole cherry. Several were anaerobic naturals: the cherries first fermented in sealed tanks without oxygen before drying.
For one Gesha lot, that fermentation lasted five days, with temperature, acidity and sugar levels tracked throughout. The cherries then dried on raised beds. These small lots reflect the range of processing methods Alejo explores at Volcán Azul.
The family also says it has protected more than 1,500 hectares of rainforest, including land on the Osa Peninsula in southern Costa Rica.
