ABSTRACT
A quantitative sensory method was developed to evaluate young red
wines from Rioja Alavesa and find the most suitable attributes to describe
them. Twenty-four attributes (including appearance, aroma, flavor, taste and
mouthfeel attributes) were chosen. Combined quantitative references were
developed for these attributes aiming to lower the total number of references
to be tasted. Nineteen wines were evaluated at four different times (every 2.5
months after bottling) by a panel trained in the use of this methodology.
Attributes were compared in terms of overall intensities, and discriminative
power of the attributes was assessed by analysis of variance, considering both
sample and time effects. Appearance, taste and mouthfeel attributes revealed
to be the most important to describe and discriminate the wines. “Red berry,”
“floral,” “aroma intensity” and “dark berry” were the most important
aroma attributes to discriminate among the wines, whereas “alcoholic” and
“herbaceous” were the most important in flavor.
PRACTICAL APPLICATIONS
This work provides three main practical applications. First, a list of terms
for sensory description of wines from Rioja Alavesa is provided. There are no
