How does the geisha coffee roast curve build tea notes?
Panama Emerald Estate geisha coffee is known for delicate floral aroma and a tea-like body, and the Red Label grade is the higher-tier expression. Holding those traits through the roast depends on charge temperature, heat, airflow, and the dehydration and first crack milestones. The profile charges at a drum temperature of 150°C and drops at 189.5°C.
In the documented roasting process, heat is set to 120 with airflow at 3; the turning point arrives at 1 minute 36 seconds, and at 140°C airflow moves to 4. At 147.6°C the bean surface yellows and the grassy smell fades, marking dehydration; at 150°C heat drops to 100, and by 7 minutes 38 seconds wrinkles and dark patches appear.
