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.

La haie bocagère comme critère de zonage à l’échelle parcellaire

In the French AOCs, the production area of ​​the raw material can be subject to plot delimitation based on criteria of physical environment and use. On the other hand, many environmental zonings are developing and the AOCs are called upon include provisions relating to these concerns. Hedges, through their effects on local changes in the regional climate and on functional biodiversity, can impact the functioning of vines and orchards. It is for this reason that their consideration as a delimitation criterion is envisaged.

Sensory profile: a tool to characterize originality of wines produced without sulfites

A trend to reduce chemical inputs in wines exists, especially sulfur dioxide (SO2). This additive is widely used due to its antioxidant, antiseptic and antioxidasic properties. During without sulfites vinification, bioprotection by adding yeast on harvest could be a sulfites alternative. With extension of this wine market, sensory impact linked to sulfites absence and/or sulfites alternative should be evaluated. That’s what this approach proposes to do, focusing on sensory characteristics of wines produced with or without SO2 addition during the winemaking process. METHODS: Wines were elaborated from Merlot grapes of two maturity levels according to three modalities: SO2, without SO2 and bioprotection on harvest (mix of Torulaspora delbrueckii and Metschnikowia pulcherrima). SO2 modality was sulfited throughout the winemaking and aging processes whether other modalities received any addition. After two years of aging, sensory studies were carried out with a specific panel for one month. First, descriptors were generated to differentiate the wines, then panelists were trained on these specific descriptors for five sessions and finally wines sensory profiles were elaborated
