Resumo(s)
Aim: The evolution of global phenolic parameters and the sensory profile of a Portuguese red wine aged for 90 days in contact
with wood chips from different species were evaluated.
Methods and results: For this purpose, wood chips from cherry (Prunus avium), acacia (Robinia pseudoacacia) and two oak
species (Quercus petraea and Quercus pyrenaica) were added to a Portuguese red wine. Various global phenolic parameters of
red wines were studied during the aging process (90 storage days). In addition, a sensory analysis was made after the 90-day
aging period to determine the impact of the use of different wood chip species on red wine sensory profile. The results showed
that during the aging period, only a few differences were detected between the wines. However, after 90 aging days, in general
the wines aged in contact with cherry wood tended to have the lowest values for several phenolic parameters. For sensory
parameters, the wine aged in contact with French oak chips showed significantly higher scores for several aroma descriptors,
while for visual and taste descriptors no statistical significant differences were found between the wines.
Conclusion: At the concentration used (3 g wood chips/L wine), the different wood chip species studied had no clear influence
on the evolution of the majority of the red wine phenolic parameters. However, from a sensory point of view, the use of
different wood species induced greater differentiation, especially for aroma descriptors.
Significance and impact of the study: The outcomes of this study would be of practical interest to winemakers and regulatory
institutions since they could improve the knowledge of the impact of alternative wood chip species, namely acacia and cherry,
on red wine quality
