       The objective of this research was to determine effect of coffee origin and genotype on organoleptic and physical quality of Arabica coffea L. growing in North Sumatra. Seven districts treated as origins and 28 genotypes were chosen. The research was conducted with nested design with 3 factors. Organoleptic parameters were fragrance/aroma, flavor, aftertaste, acidity, body, uniformity, balance, clean cup, sweetness, overall and total score. Physical quality was green bean weight. The results revealed that origins affected significantly organoleptic quality. Coffee from Dairi showed the highest total score (90,82). Genotypes were significantly different in organoleptic quality. Genotype Da17, Da18, Da19, Da20 and Hu4 had the best total score (89,85 - 91,68). Total score did not correlate with green bean weight but had positive correlation with altitude. Among organoleptic parameters, acidity was more significant for total score (r2 = 0,836). Altitude had more effect on acidity (r2 = 0,486).
