Geisha Coffee Variety
Geisha green beans are slender in shape and have a clean, bright flavor. Because of these two characteristics, they do not resemble Central and South American varieties so much as they are closer to Ethiopian coffee. When was Geisha introduced to Panama?
The Geisha variety was discovered in 1931 in the Geisha forest of Ethiopia and was later sent to the Kenya Coffee Research Institute; in 1936 it was introduced to Uganda and Tanzania, and in 1953 Costa Rica imported it. For a long time, it did not attract much attention. Later, Don Pachi brought Geisha from the
In terms of green bean appearance, the Bolivian Java variety is slender with relatively pointed ends; the Janson Geisha green beans are slightly shorter and more rounded.

Front Street Coffee Roasting Record
Janson Geisha: These coffee beans are larger and denser, absorbing a great deal of heat during roasting, and the Maillard reaction progresses relatively quickly.
The drum temperature was raised to 200°C for charging, the air damper opened to 3.5, and after 30 seconds the heat was adjusted to 160°C with the air damper set to 3; the turning point was at 1'32", and at a drum temperature of 153.3°C the heat was adjusted once—by this time the bean surface had turned yellow, the grassy scent had disappeared, and dehydration was complete—so the heat was lowered to 140°C and the air damper set to 4; at 9'0", wrinkles and dark patches appeared on the bean surface, the toasted bread aroma shifted distinctly to coffee fragrance, and the pre-first-crack phase began; listen carefully for the sound of first crack, which started at 9'47"—reduce the heat to 50°C and open the air damper fully to 5 (be very cautious when adjusting the heat; do not reduce it so much that no cracking sound is heard); after first crack, develop for 2'40" and drop at 197.1°C.
Bolivian Java: To highlight the natural process's sweetness and cocoa aroma, Front Street adopted a roasting approach with an extended development phase to present a sweet and delicious flavor. Using the Yangjia 800N as an example, 500g of green beans were used.
The drum temperature was 170°C for charging, heat at 120, and the air damper opened to 3; the turning point was at 1'36", and at a drum temperature of 111°C the air damper was opened to 4 and the heat adjusted to 140; at a drum temperature of 151.1°C the bean surface turned yellow, the grassy scent disappeared, and the dehydration phase began; at 7'56" wrinkles and dark patches appeared on the bean surface, the toasted bread aroma shifted distinctly to coffee fragrance, and the pre-first-crack phase began, with the air damper adjusted to 5. At this point, listen carefully for the sound of first crack, which started at 10'18"; after first crack, develop for 1'00 and drop at 190°C.
Front Street Coffee Cupping Report
[Janson Geisha] The dry aroma has the fermented fragrance of ripe fruit, with flavors of maple syrup, lemon, citrus, apple, rose, dark chocolate, fruit, pomegranate, ripe grape, peach, and dark berries—a rich layering of sweetness and acidity.

Front Street Coffee Brewing Comparison
Dripper: HARIO V60 Water temperature: 90°C Coffee-to-water ratio: 1:15 Grind size: fine sugar consistency
Front Street Coffee uses a staged extraction: first bloom with 30g of water for 30 seconds, then pour in a slow circular stream until the scale reads 125g and pause; when the water level drops and is about to expose the coffee bed, continue pouring until 225g and stop; when the water level drops again and is about to expose the coffee bed, remove the dripper. (Timing starts from the beginning of the bloom.) Total extraction time is 2'00".
