There is a large bibliography on descriptive sensory analysis of wines. Free-choice profiling, a new descriptive sensory technique, was applied to develop a profile with respect to appearance, aroma and taste for seven Brazilian Welchriesling wines. Twelve panelists, without experience with the technique, were selected using triangular tests. The Grid method was used to obtain the list of descriptors. The number of attributes developed for each judge vary from seven to thirteen. Generalized Procrustes Analysis were applied to the data. During fifteen days, fifteen sessions were realized: two to select the assessors, four to develop the terminology, two to check the score sheets and seven to evaluate the wines (balanced incomplete block design). It was observed good discrimination between the samples. Wines were differentiated mainly by taste attributes (acid, "astringent", alcoholic, sweet and fruity), correlated with dimension 1 (25% of variance), and one appearance attribute (yellow color), associated with dimension 2 (9% of variance).
