Sweet as peach candies, delicate as tea, and yet beautifully clean—that’s exactly what Letty Bermudez from the Canadian roastery September Coffee is like. This Colombian Geisha is characterized primarily by an intense sweetness reminiscent of ripe peaches and peach jelly, complemented by a delicate floral note and a subtle oolong-style tea character. The aftertaste leaves a long, sweet, and elegant trail, so despite its distinctive fruity profile, the entire cup feels very smooth and clean.
The coffee comes from the Finca El Paraiso farm in the Cauca region of Colombia, where it is grown at an elevation of approximately 1,930 meters above sea level by producer Diego Bermudez. He is one of the most renowned figures in modern experimental coffee processing, and his approach is based on precise control of each stage of fermentation. Instead of conventional fermentation tanks, he uses bioreactors in which he monitors temperature, pH, sugar content, and microbial activity. It is precisely this control that helps create a distinctive yet very clean and well-defined flavor profile.
The processing combines double anaerobic fermentation, the washed method, and thermal shock. The cherries are harvested at peak ripeness, then hulled and fermented with selected tropical yeasts that enhance the coffee’s fruity character. Further fermentation takes place under pressure with a culture prepared from pulp and mucilage to help the aromatic precursors bind more effectively to the bean. This is followed by thermal shock, which stabilizes the process and helps preserve the developed aroma. The coffee is finally dried in a dehumidifier, which limits oxidation and helps maintain its delicacy and purity. The Geisha variety itself adds its characteristic floral notes, lightness, and peachy character.
