COSTA RICA MONTANO MICRO-MILL ANAEROBIC

Beneficio San Diego, Costa Rica’s most innovative and largest private mill, acquired Montano Micro Mill with a plan to take experimentation to the next level. Montano is led by Juan Ramon, a local producer with a strong reputation for high quality. 

The Anaerobic process begins with the selection of handpicked ripe, red coffee cherries. Selecting the cherries when they are at their ripest ensures a high sugar content, which helps feed the anaerobic process.

At the mill, the coffee is depulped with a portion of the mucilage left intact. From there, the coffee is put in air-tight, stainless-steel tanks with the mucilage left on. The absence of oxygen stimulates an anaerobic fermentation process. The process develops in a unique series of acids such as lactic and malic, which results in a very complex flavor. Once the coffee has been fermented sufficiently, it is dried to 11.5% moisture and rested to allow complex and exotic flavors to develop.
