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.

Budburst delay and berry ripening after vegetal oil application in Austria

Occurrence of freezing temperatures in early spring when grapevine shoots are developing is termed late frost in viticulture. Young green tissues are very sensible to temperatures below zero and damages often lead to important yield and quality losses such as the case in Europe in 2017. An indirect method to avoid late frost damage in vineyards consist in delaying the budburst. Previous research reported similar effects by applying vegetal oil on dormant buds. Here, we tested the application of rapeseed vegetal oil during late winter to delay the budburst on two V.vinifera cultivars of interest in Austria, Grüner Veltliner (GV) and Zweigelt (ZW).

Smoke tainted wine – what now?

The frequency of bushfires close to wine regions around the world has increased in the last two decades. The economic losses incurred when grapes and wines are discarded due to ‘smoke taint’ are substantial (i.e., hundreds of millions of dollars). Efforts to mitigate and ameliorate smoke taint are therefore crucial. Chardonnay, rosé and cabernet sauvignon wines made from grapes exposed to smoke during the 2020 wildfires in eastern Australia were subjected to various amelioration techniques: the addition of activated carbons, molecularly imprinted polymers (mips), and a proprietary resin (either directly, or following membrane filtration); spinning cone column (scc) distillation; and finally, transformation into vinegar.

Comparative QTL mapping of phenology traits in three cross populations of grapevine

Long-term studies on grapevine phenology have clearly demonstrated that global warming is affecting phenological events, leading to an anticipation in their timing, and negatively impacting grape yield and berry quality. Therefore, dissecting the genetic determinants involved in the plant regulation of the phenological stages of budburst, flowering, veraison and ripening can improve our knowledge of the underlying mechanisms and support plant breeding programs and the advancement of vineyard management strategies.
We report here the results of a QTL mapping experiment conducted on three segregating populations obtained from the crossing of ‘Cabernet Sauvignon’ and ‘Corvina’, ‘Corvina’ and the hybrid ‘Solaris’ and ‘Rhine Riesling’ and ‘Cabernet Sauvignon’.
