Monteblanco Purple Caturra Passionfruit

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. 

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. 

This Passion Fruit Co-fermented Washed process begins with the creation of the fermentation culture that will be used. First, a mother culture was created containing microorganisms like lactobacillus and saccharomyces cerevisiae. 80 liters of this culture is separated to be fed with passion fruit, cholupa fruit, and a sweetener like panela or molasses. The cholupa and passion fruit contribute flavor to the culture, while the sweetener energizes the fermentation and brings the culture’s sugar content to a level that matches the degrees Brix of the coffee that will be processed. This initial fermentation of mother culture and fruit takes 190 hours to reach the appropriate degrees Brix and pH value for coffee processing.  

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 pulped and 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.
