COLOMBIA RODRIGO SANCHEZ VALENCIA CITRULLUS NECTAR CO-FERMENT WASHED

Finca Monteblanco, located high along the winding mountain roads of Vereda La Tocora in the San Adolfo municipality above Pitalito, is a family farm managed by Rodrigo Sanchez Valencia in the tradition of coffee cultivation that began with his grandfather. Monteblanco’s 18 hectares sit on the crest of a hill, with the wet mill and drying facilities at the top of the farm and slopes of coffee planted below. 

In 2002 Rodrigo participated in a local program teaching local children of coffee producers to cup. Before that, he and his family had never considered coffee in terms of cup profile. By learning to differentiate profiles, he and his father and grandfather were able to make the connections between the farming techniques they applied and coffee’s resulting attributes in the cup. 

At this time, Rodrigo also began to learn about cupping competitions that evaluate the best lots from farms in a region. He noticed that farms would win one year and then never again, so he decided to investigate how to produce quality coffee consistently. This led him to explore the trees planted on Monteblanco, where he discovered various varieties, his grandfather had planted in the 1980’s. One of these varieties is Purple Caturra, a type of Caturra whose cherries ripen to a deep purple color. 

Rodrigo is proud that he, his wife Claudia Samboni, farm manager Don Gerardo, and the team that works in the fields and at the mill have reached the goal of achieving consistent quality. Finca Monteblanco produces microlots with each harvest that serve as competition coffees around the world, but the farm also consistently produces containers of delicious coffees that appear year-round on café menus and retail shelves. By applying an ethic of rigorous monitoring, planning, and management at each stage of production and processing, all coffees from Monteblanco showcase their full potential. 

Harvesting and processing on Monteblanco have had to evolve with the times, adapting to a changing climate that yields harvest times dispersed through ten months of the year rather than in a concentrated peak. Coffees from Monteblanco are milled and prepared for export at the new, state-of-the-art Aromas del Sur drymill in Pitalito.

To start this fermentation, a mother culture is made using nectar from the Citrullus family (watermelon, melon). Microorganisms from coffee cherries are blended with this nectar and other sweeteners. 

The coffee cherries are then fermented with this mother culture for 190 hours. This careful fermentation process ensures that the Brix levels stay above 6 and the pH remains above 4.

Before being processed with the fruit-fermented culture, coffee cherries are measured for sugar content as soon as they reach the mill at Monteblanco. Cherries are then floated to remove impurities before being deposited into a 200 liter sealed tank. The 80 liter culture that was previously fermented with the fruits is added to the sealed tank, and the coffee is fermented for 150 hours. During this process, the team keeps measurements to ensure that the environment doesn’t fall below 6 degrees Brix, or below a pH of 4. The coffee is then moved to the drying area, where it is dried for 2–3 days in direct sunlight and then for 15–18 days under shaded canopies until it reaches 10–11% humidity.

Watermelon has been one of our favorite co-ferments because of its uniqueness and depth of flavor. Typically, watermelon is a flavor associated with something cold. Drinking this coffee hot brings a new experience of the watermelon flavor and how it integrates into the cup.
