In Brazil the recommendation of new cultivars of beans has been done according to the grains agronomic characteristics. However, in the last years researchers of the Genetic Improvement of Beans Program have recognized the importance of technological characteristics, mainly the sensory profile of cultivars of beans and their acceptance by consumers. So, it makes evident the need for sensory characterization of the cultivars of beans that are already suggested to cultivation and those that are ready to be. The present work aimed at carrying out the sensory evaluation of seven kinds of beans grains recommended to the State of Minas Gerais (Ouro Negro, Meia Noite, Carioca, Aporé, Rudá, Pérola, and Vermelhinho) and of three promising pure lines for releasing (MA733327, Vermelho2157, and CB733812). These cultivars and pure lines were produced by the UFV. All the samples were cooked in pressure cooker for 23 minutes and served to the tasters. Quantitative descriptive analysis was applied to verify similarities and differences in the appearance, smell, flavor, and texture of the beans. A panel composed by eight tasters, who were previously selected and trained, evaluated the samples of beans. The sensory acceptability of the ten samples was also evaluated by 30 consumers, picked randomly near the sensory analysis laboratory (DTA/UFV). To the affective test, the samples were spiced. The ten cultivars of beans differed significantly (p<0,05) in relation to the sensory attributes defined by the panel (Grains with Tegument Rupture, Brown Color, Black Color, Color Uniformity, Characteristic Flavor, Bitter Taste, Hardness, Granularity, and Residual Skin), except for the attribute Sweetened Flavor. The lines presented sensory profile similar to the kinds, except for Color Uniformity (line Vermelho2157), Hardness e Granularity (lines CB733812 and MA733327) and Residual Skin (line CB733812). These characteristics need to be modified before to recommend the lines for cultivation. The majority of the consumers gave scores 7 or 8 for beans cultivars acceptance. There was no significant difference (p>0,05) in the acceptability of the cultivars. All of them had positive acceptance and were rated within the hedonic terms "liked moderately" and "liked very much."
