Beyond colors of rosé wines: impact of origin and winemaking technology on their color, polyphenol and thiol compositions

Abstract

Rosé wine consumption is rapidly increasing with its market share in France that has grown from 11 % to 32 % in less than 20 years. A recent trend is also to produce rosé wines with lighter colors. Varieties, terroir and technology certainly have an influence on rosé wine colors. We used different analytical techniques (colorimetry, UPLC-MS) and data management strategies (molecular modelling and multivariate discrimination analysis) to investigate the relationship between natural and human factors on the final composition of rosés wine. We showed that some polyphenols can be key markers of the origin for 60 commercial wines from the Bordeaux, Languedoc and Provence regions. We also demonstrated that PVPP treatment reduces the color of rosé wines by specifically adsorbing some classes of polyphenols and pigments like coumaroylated anthocyanins. This specific adsorption phenoma was explained by molecular modelling calculations of interactions between anthocyanins and PVPP. Finally we showed for the first time that the thiol aromatic indexes of rosé wines can be increased by PVPP treatment up to 200 % compared to the control.

SIP and save the planet: a sensory and consumer exploration of australian wines made from potentially drought-tolerant white wine grapes

In order to attenuate the effects of climate change on the ability to cultivate quality wine grape vines in Australia, it is essential to adapt to the projected less favourable Australian climate scenarios. One response may be to convert a portion of the current grapevine plantings to those varieties that demand less water and can tolerate increased heat. This investigation aimed to (i) generate sensory profiles and (ii) obtain knowledge about Australian wine consumers’ preferences and opinions of Australian wines made from potentially drought tolerant, white wine grape varieties not traditionally cultivated in Australia. A Rate-All-That-Apply (RATA) sensory panel (n = 49) generated sensory profiles of 44 commercial white wines made from 7 different white grape varieties (Arinto, Fiano, Garganega, Greco, Verdejo, Verdelho and Vermentino), plus two benchmark examples each of an Australian Riesling, Pinot Gris and Chardonnay wine.

Panorama des actions d’amélioration variétale face aux challenges d’aujourd’hui et de demain, le rôle de l’IFV

In April 2024, the French official catalog includes 449 grape varieties and rootstocks. In 10 years it has been enriched with 70 varieties. It is an indisputable marker of the interest of professionals in genetic resources of all origins and the expectations they have to prepare the viticulture of the future. The scientific community has now put all irons in the fire and is not neglecting any avenue of adaptation. The regular decline in the use of phytosanitary products and the already marked effects of climate change are the targets of varietal improvement.

New oenological criteria for selecting strains of Lachancea thermotolerans for wine technology

The study conducted various fermentations of different grape juices using various strains of Lachancea thermotolerans and one strain of Saccharomyces cerevisiae. Because of the new conditions caused by climate change, wine acidity must be influenced as well as the volatile profile. Non-Saccharomyces yeasts such as L. thermotolerans are real options to mitigate the impact of climate change in wine production.
