Valoración del potencial enológico de la madera de roble Quercus Pyrenaica de La Rioja para la crianza en barrica de vinos tintos

Abstract

[ES] En la barrica se producen importantes modificaciones en la composición de los vinos debidas al aporte de sustancias por la madera de roble y a los procesos oxidativos que se favorecen. La especie y origen de la madera de roble son factores con gran influencia en este proceso. El roble americano se ha utilizado mayoritariamente debido a criterios económicos, pero desde hace tiempo se observa una tendencia creciente hacia el empleo del roble francés y de otros países europeos. En España existe una importante superficie forestal de la especie Quercus pyrenaica, cuya madera ha sido caracterizada con resultados muy favorables para su aprovechamiento en tonelería, lo que podría suponer un notable incremento de su rentabilidad. Teniendo en cuenta la gran demanda de madera de calidad y las posibilidades enológicas de la especie Q. pyrenaica, se planteó la realización de este trabajo. Un vino tinto Tempranillo de la D.O.Ca. Rioja se envejeció durante un año en barricas de roble español de la especie Q. pyrenaica, procedente de La Rioja, en comparación con las maderas tradicionales usadas en tonelería (Q. alba americano y Q. petraea francés). Se observaron pequeñas diferencias en el contenido polifenólico de los vinos, que experimentó menor evolución en las barricas de roble francés. El aporte de volátiles de la madera fue más intenso en el roble americano, menor en el francés e intermedio en el procedente de La Rioja. En el análisis sensorial todos los vinos fueron bien valorados, apreciándose pequeñas diferencias cualitativas atribuibles al origen del roble, que pueden contribuir a una mayor diversificación de sus características.

[EN] In the barrel produced significant changes in the composition of the wine due to the contribution of substances by oak and oxidative processes are favored. The species and origin of oak wood are influential factors in this process. American oak has been used mainly because of economic criteria, but has long been a growing trend towards the use of french oak and other european countries. In Spain there is an important forest area of Quercus pyrenaica species whose wood has been characterized with very favorable for their use in cooperage results, which could be a significant increase in profitability. Given the high demand for quality wood and oenological potential of the species Q. pyrenaica, the completion of this work was raised. A red wine from Tempranillo D.O.Ca. Rioja was aged for a year in oak barrels Spanish Q. pyrenaica species, from La Rioja, compared to traditional woods used in cooperage (Q. alba american and Q. petraea french). Small differences in the phenolic content of the wines, which experienced minor evolution in french oak barrels were observed. The contribution of volatile wood was more intense in american oak, minor in french and intermediate in from La Rioja. The wines were all highly rated sensory analysis where small qualitative differences attributable to the origin of the oak, which may contribute to further diversification of its features.
