Aceh is one of the center of Indonesian arabica coffee which has unique taste and flavor. The variability of arabica coffee is very diverse due to soil, climate and altitude variations. Balittri-IAARD recently released arabica Gayo 1 variety originally from Central Aceh District. The purpose of this study was to evaluate the caffeine content and sensory differences of each Gayo 1 and Gayo 3 arabica coffee among a three-level grown altitude. Both varieties of coffee were grown at 900, 1300 and 1500 m asl in Central Aceh District. The sensory quality was tested by the cupping method following SCAA (Specialty Coffee Association of America) protocols. The caffeine content in Gayo 1 and Gayo 3 ranged from 1.14-1.70%, whereas the value was inclined from 900 to 1300 m asl and turned down at 1500 m asl. Cupping analysis of Gayo 1 and Gayo 3 had scores> 80; it was categorized as specialty coffee. Coffee was grown at 900 and 1300 m asl had an excellent category with a cupping score of 85-89.99.
