Effect of Quercus Alba oak barrels from different forests on the polyphenolic composition of Tempranillo red wines

Abstract

AIM: The species and origin used for red wine oak aging determines the physiological composition of the wood and thus the finished wines. In America, oak is grown primarily in the states of Virginia, Missouri, Kentucky, Oregon, Ohio, Minnesota, Wisconsin and California. The aim of this study was to analyze how the choice of barrels made with Quercus Alba oak from different geographic areas of the United States (Missouri, Kentucky, Ohio and Pennsylvania) influences the polyphenolic composition of Tempranillo red wines.

METHODS: In this study, twelve different Tempranillo wines were aged for 12 months in new 225-liter American oak barrels (medium toast degree) from different forest of the United States: Missouri, Kentucky, Ohio and Pennsylvania. These barrels were made by the Toneleria Murua in 2018 and the experiences were carried out in twelve wineries of the D.O.Ca Rioja and D.O. Rueda. Samples were taken when the wines after 6 and 12 months of aging. The monomeric phenolic compounds were quantified by high performance liquid chromatography with diode array detector (HPLC-DAD) according to the methodology proposed by Gómez-Alonso et al. (2007).

RESULTS: After 12 months of aging, wines aged in Missouri oak showed significantly higher values of total anthocyanins and stilbenes. Wines aged in Kentucky and Ohio oak showed significantly higher values of total flavonols and ellagitannins. Wines aged in Pennsylvania barrels showed higher concentrations of catechin. 

CONCLUSIONS: The results showed that the geographical origin of the Quercus Alba oak significantly affected the polyphenolic composition of the wines. The results obtained in the present study could help for selecting the oak origin that best suited to the different wines.

ACKNOWLEDGEMENTS: The authors would like to thank the Gobierno de La Rioja for the funding provided for this study through the project ADER2019-I-IDD-00067.

Kinetics modeling of a sangiovese wine chemical and physical parameters during one-year aging in different tank materials

The use of different tank materials during red wine aging has become increasingly popular, but little is known about their impact on wine chemical and physical parameters.

Towards a European data basis based of advanced multi-isotopic signatures and artificial intelligence: the wine in blue project

Major and trace elements are essential for the development of grapes used for the wine. They are primarily originating from the soil. Some elements are also seldomly added during the wine making process. Therefore, the largest spectrum of major, trace and ultra-trace elements in the final wine product is a good signature of its geographical origin. In the frame of the European tracewindu, we have developed a very original multi-isotopic dilution method using triple quadrupole icp/ms.

A new graphical interface as a tool to integrate data from GC-MS and UPLC-MS-QTOF: new compounds related with port wine aging

Port wine value is related to its molecular profile resulting from the changes occurring during the ageing period. It is of empirical knowledge that the style is greatly affected by the oxidation regimens, i.e. bottle versus barrel storage

LCA: an effective, generalizable method for wine ecodesign? Advantages and limitations

Life cycle assessment (LCA) is an effective and comprehensive method for evaluating the environmental impact of a product, considering its entire life cycle. In the context of wine production, although the use of lca is gaining ground in viticulture, its application is still limited to the fine assessment of winemaking processes.

Effect of spray with autochthonous Trichoderma strains and its secondary metabolites on the quality of Tempranillo grape

Trichoderma is one of the most widely used fungal biocontrol agents on vineyards due to its multiple benefits on this crop, such as its fungicidal and growth promoting capacity. In this work, we have analyzed the effect on the concentration of nutrients in grapevine leaves and on the quality of the grape must after spraying an autochthonous strain of Trichoderma harzianum and one of the main secondary metabolites produced by this genus, 6-pentyl-α-pyrone (6PP).
