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.

Effects of soil water content and environmental conditions on vine water status and gas exchange of Vitis vinifera L. cv. chardonnay

Vine water status has a significant influence on vineyard yield and berry composition (Williams and Matthews, 1990; Williams et al., 1994). It has been hypothesized that the response of plants to soil water deficits may be due to some sort of “root signal” (Davies and Zhang, 1991). This signal probably arises due to the roots sensing a reduction in soil water content or an increase in the mecanical impedance as the soil dries out.

Advancing grapevine science through genomic research

The seminar will examine the complexities and prospects of genomic research on Vitis species, characterize by exceptionally high heterozygosity and common interspecific gene flow. The seminar will showcase case studies highlighting the critical role of diploid genome references in grape research, specifically in areas such as aroma development, disease resistance, and domestication traits. It will also address the emerging focus on pangenomes within the Vitis genus, particularly in the context of genetic studies on naturally interbreeding populations.

HYBRID GRAPEVINE CV BACO BLANC, BETWEEN TRADITION AND MODERNISM: FOCUS ON ENDOGENOUS EUGENOL AS RESISTANCE FACTOR TO BOTRYTIS CINEREA

The well-known antifungal and antibiotic molecule, eugenol, is widely spread in various plants including clove, basil and bay. It is also abundant in the hybrid grapevine cultivar (cv) Baco blanc (Vitis vi-nifera x Vitis riparia x Vitis labrusca), created by François Baco (19th century) in the Armagnac region. This study confirmed this cv as highly resistant to Botrytis cinerea by comparing fruit rot incidence and severity with two Vitis vinifera cultivars: Folle Blanche and Ugni Blanc. We have demonstrated the efficiency of eugenol in vitro, by further investigating the effect of small concentrations of eugenol, 3 to 4 ppm (corresponding to IC10), on B. cinerea. By comparing the two major modes of action (direct or volatile antibiosis), the vapour inhibiting effect of eugenol was more powerful. In the skin of Baco blanc berry, the total eugenol concentration reached a maximum at veraison, i.e. 1118 to 1478 μg/kg.
