The influence of the technological variables over the sensorial attributes of roasted coffee were evaluated by certified Q-Graders using the protocol established by the Specialty Coffee Association of America (SCAA). The samples presented differences statistically significant (p < 0.05) in the fragrance/aroma values (Cusco 7.18 ± 0.37, Tingo María, 7.09 ± 0.32) and acidity (Tingo María, 7.23 ± 0.23, Cusco, 7.13 ± 0.27). In the effect of the roasting temperatures, samples presented differences statistically significant in all attributes evaluated at 135°C and 140°C. Changes in the flame level during toasting (2.0 → 1.5, 2.0 → 1.0) showed differences statistically significant in flavor expression (2.0 → 1.5, 7.13 ± 0.42; 2.0 → 1.0, 7.03 ± 0.35), body (2.0 → 1.5, 7.4 ± 0.26; 2.0 → 1.0, 7.31 ± 0.26) and balance (2.0 → 1.5, 7.04 ± 0.38, 2.0 → 1.0, 7.15 ± 0.41). The effect of the degree of opening of the air intake of the roasting drum presented significant differences in the acidity of the samples (0 → 50%, 7.15 ± 0.25, 0 → 100%, 7.21 ± 0.26). Sampling times resulted in statistically significant differences in fragrance/aroma (7.3 ± 0.25 and 7.43 ± 0.24), flavor (7.13 ± 0.37 and 7.38 ± 0.29), aftertaste (7.01 ± 0.28 and 7.1 ± 0.26), acidity (7.24 ± 0.2 and 7.39 ± 0.22), balance (7.15 ± 0.4 and 7.42 ± 0.24) and overall score (7.01 ± 0.36 and 7.32 ± 0.22) between the samples at 90'' and 60'' respectively, whereas the samples exited at 30“ and 120“ did not present statistically significant differences; the body presented statistically significant differences at 30'' (7.14 ± 0.19) and 120 '' (7.27 ± 0.23) but not significant between 60'' (7.55 ± 0.21) and 90'' (7.48 ± 0.22).
