Abstract: | "Nineteen samples of commercial Galician orujo spirits were analyzed by gas chromatography and distinguished from one another on the basis of the concentrations of major volatile compounds (methanol, higher alcohols, esters, acetates, and aldehydes). The spirits were also sensorily analyzed to emphasize this differentiation and to establish a sensory profile as a function of the attributes defined by the tasters. The results show that the Galician orujo spirits present notably significant differences in the concentrations of 2-butanol, methanol, acetaldehyde, and ethyl lactate, whereas their ethylic esters contents are similar. Sensorily, the orujo spirits can be differentiated by taste but have similar characteristics of bouquet, the best of which are from the Godello variety. The descriptions employed to define the orujo spirits were herbaceous, floral, fruity, vegetal, alcohol, toasted, and 'others'. Floral and fruity were predominant in the Albarino orujo spirits; herbaceous was predominant in the plurivarietal orujo spirits, vegetal in the Godello spirits, and dried fruit or toasted in the Mencia spirits. The orujo spirits from Treixadura have the most diverse profile, with the participation of most of the attributes" |
