ResumenSensory evaluation of foods and beverages is usually carried out by using conventional techniques such as quantitative descriptive analysis. Most of this techniques imply the use of trained and experienced assessors, who normally tend to generate complex and scientifically orientated vocabulary. In contrast, Free Choice Profile is a sensory methodology that requires little training and allows to gather information about cognitive perception directly from consumers (Moskowitz, 1996). A more structured approach of it has been developed incorporating the Repertory Grid Method as a previous step. This method is particularly suited for vocabulary development and therefore can solve the difficulties in generating enough and adequate descriptors usually presented when working with consumers (Jack & Piggott, 1991).
