The aim of this work was to study the cooperage potential of the oak species Quercus pyrenaica, which is widespread throughout the Iberian Peninsula. A red wine of 2016 vintage was aged in new barrels made from Quercus pyrenaica, Quercus petraea and Quercus alba for 12 months. This process was repeated with a similar red wine from the subsequent vintage using the same barrels in order to compare the performances of the new Q. pyrenaica barrels and Q. pyrenaica barrels that had been used for one year with equivalent Q. petraea and Q. alba barrels. The results indicate that Q. pyrenaica releases levels of β-methyl-γ-octalactone similar to those released by Q. alba and clearly higher than Q. petraea, whereas it releases levels of ellagitannins similar to Q. petraea and clearly higher than Q. alba. These data indicate that Q. pyrenaica is more similar to American oak from an aromatic point of view, since it provides mainly coconut notes, but is more similar to French oak in terms of wine structuration. Moreover, based on the preferences of a trained panel, the wines aged in the Q. pyrenaica barrels were ranked in second position, just behind the wines aged in the Q. petraea barrels and ahead of those aged in the Q. alba barrels. Consequently, Q. pyrenaica seems to have characteristics midway between the two most commonly used oak species for cooperage, confirming its high potential in this regard.

International audience; Los taninos enológicos se utilizan habitualmente en la elaboración del vino por diversos motivos (Versari et al., 2013; Vignault et al., 2018), entre los que destacan su acción inhibitoria de la actividad lacasa en las vendimias afectadas por la podredumbre gris y la protección del color del vino frente al pardeamiento. No obstante, hasta hace muy poco este efecto anti-lacasa era tan solo empírico sin que existieran pruebas científicas de ello. Por esta razón, la OIV creo un grupo de trabajo específico para estudiar las verdaderas aplicaciones de los taninos enológicos. Fruto de sus investigaciones son los resultados que se presentan a continuación que demuestran la efectividad de los taninos enológicos para inhibir la actividad lacasa y proteger de este modo el color del vino (Vignault et al., 2019; Vignault et al., 2020).
