Microorganisms influence the sensory quality of the coffee beverage through the compounds degradation or release of metabolites that diffuse into the fruit. However, type and duration of fermentation can contribute to the growth and diversity of microorganisms. Thus, the objective of this study was to analyze the microbial and sensory profile of Arabica coffees under different fruit-processing conditions and fermentation by Saccharomyces cerevisiae. Coffee cherries were used in the dry fermentation and washed fermentation at 28°C. Fermentation time ranged from 36 to 288 hours. A panel of sensory attributes was evaluated by 9 Q-graders. Mid-infrared spectra were obtained in the wavenumber range from 4000 to 650 cm?1. Microbial analyses were performed by denaturing gradient gel electrophoresis. Total sensory score for fermented coffee was higher than for unfermented coffee. In 108 and 216 hours of fermentation, the total score was higher in washed fermentation than in dry fermentation, which also shows the influence of post-harvest processing and the removal of husk on the quality of fermented coffee. Balance and body were the sensory attributes that most contributed to group formation in dry fermentation. Thus, induced fermentation increases the sensory classification of coffee beverages with positive effects on chemical and sensory profiles. |

When it comes to the sensory analysis of specialty coffees, it is necessary to discuss the protocol of tests of the Specialty Coffee Association (SCA) and the formation of Q-Graders as reliable parameters in the sensory analysis. However, the training of these Q-Graders and the use of the SCA protocol has generated discussions in the scientific community and demonstrated the importance of talking about the level of professional precision as well as the use of the protocol. This study sought to understand the relation of accuracy and efficiency of the Q-graders and protocol in the sensory analysis of coffees. Three experiments were carried out to evaluate and test the hypotheses regarding the level of precision in relation to the shift, the number of samples and the judgment abilities of Q-Graders due to the quality of the specialty coffee and non-specialty coffee. These three experiments were performed by seven Q-Graders in an isolated environment during three consecutive days with 137 specialty coffee samples and 7 non-specialty coffee samples as defined by the SCA. The results indicate that the Q-Graders present high precision when evaluating excellent and outstanding coffees, as defined by the SCA. In addition, the effect of the shift did not exert fatigue on the Q-Graders. However, evaluation errors were made by the Q-Graders on very good coffee (77.00 - 80.00 points), which are considered as non-specialty by the SCA, thus allowing a more in-depth discussion on what would be the boundary between a specialty and non-specialty coffee.
