Producer & Origin
This coffee comes from El Diviso, Nestor Lasso’s farm in Bruselas, Pitalito, Huila, Colombia, at elevations of 1,700 to 1,800 meters above sea level, where climate, altitude, and careful processing come together to create expressive, high-quality coffees.
The combination of steady temperatures, elevation, and meticulous post-harvest work helps produce a cup with aromatic lift, sweetness, and clarity. El Diviso has become increasingly recognized among specialty coffee buyers for coffees that pair innovative processing with distinctive cup character.
Processing
This lot begins with the harvesting of ripe cherries, followed by removal of floaters and a 5% alcohol wash to help eliminate impurities and bacteria before fermentation begins.
The coffee then moves through a detailed multi-stage process:
24 hours anaerobic fermentation in plastic bags at average temperatures of 18 and 16°C
20 hours oxidation in tanks
Depulping, followed by another 20 hours oxidation with mucilage
12 hours submerged fermentation with recirculated mosto
To finish fermentation, the coffee undergoes thermal shock quenching with hot water at 50°C. The sheet explains that this step helps fix volatile compounds developed during fermentation by opening the pores of the bean and stabilizing those aromatics.
Drying is completed through natural sun drying under canopy, followed by final finishing in a mechanical silo system, with a minimum rest time of 2 weeks.
About Aji Bourbon
According to the producer sheet, Aji Bourbon refers to the spicy notes present in the mucilage. It is also described as a domesticated mutation derived from an Ethiopian landrace, a genetic group of Arabica coffees originally from Ethiopia.
This makes Aji Bourbon especially interesting for coffees that aim to balance floral elegance with distinctive aromatic complexity.
