Wine samples were subjected to sensory analysis after approval
of the ethics committee (CAAE:03005412.3.0000.0121) by a team of
11 expert judges with long experience in the sensory analysis of
wine, comprised of 9 men and 2 women. The analysis was conducted
in individual testing booths under white light. The samples
were randomly served at a temperature of 18 ± 1 C in wine glasses,
identified with three-digit random codes. The judges then
described the sensory attributes of the samples individually. The
following descriptors were selected by consensus: red-ruby and
red-orange as appearance attributes and bitterness, acidity,
sweetness, viscosity, astringency and alcoholic sensation as
mouthfeel attributes. To evaluate the intensity of each attribute a 9-
cm unstructured linear scale, identified as ‘weakly perceptible’ on
the left and ‘strongly perceptible’ on the right, was used. All wine
samples were evaluated in triplicate
