Advances in the chemistry of rosé winemaking and ageing

Abstract

The market share of Rosé wine in France has grown from 11 % to 32 % over the last 20 years. Current trends are towards rosé wines of a lighter shade of pink, and where possible, containing a greater concentration in varietal thiols. Grape varieties, the soil on which they are grown, viticultural practices and winemaking technology all impact the polyphenols, color and aromas of rosé wines. To investigate the terroir effect, a study on the influence of origin of rosé wine was  performed using semi-targeted polyphenomics. 60 commercial wines from Bordeaux, Languedoc and Provence regions were used as two independent sample and data sets (30 wines each). An original LC-QTOF-MS method and a specific data analysis genetic algorithm gave good discrimination of the wines based on their origin of production [1].

Apart from the origin or terroir of the grapes, winemaking technology plays a crucial role in determining the color and aroma profile of rosé wine, including the widespread use of polyvinylpolypyrrolidone (PVPP) to adjust the color and polyphenol content. The specific adsorption of coumaroylated anthocyanins was greater than that of other anthocyanins [2], and a molecular modelling approach was used to further understand this specific binding affinity. We showed that using PVPP, the thiol aroma content of rosé wine can be increased up to 200 % as compared to the control wines [3]. This might explain the increase in demand for lighter colored rosé wines over the last number of years.

When the desired color and aroma are obtained, a remaining challenge is to understand and predict the sensitivity of rosé wines to oxidation. Accelerated ageing tests based on heat and chemical oxidation are currently under investigation in our laboratory. These tests and mass spectrometry show that the anthocyanins are appropriate biomarkers of chemical ageing in rosé wines.

CONSUMER PERCEPTION OF INTERSPECIFIC HYBRID RED WINE COLOR IN RELATION TO ANTHOCYANIN PROFILE AND CHEMICAL COLOR PARAMETERS

Interspecific hybrid winegrapes are of growing interest in the context of climate change based on their disease resistance and cold hardiness. In addition to a need for increased understanding of their chemical composition, there is little empirical evidence on the consumer perception of non-vinifera wine. Phenolic compounds, and particularly color, play an important organoleptic and quality determination role in wine, but can vary significantly in interspecific hybrid wines compared to wines produced from Vitis vinifera cultivars [1, 2, 3]. Anecdotally, the variation in anthocyanin species, interactions, and concentrations in interspecific hybrids could result in a variance from“vinifera-like” wine color.

Typologie des paysages de vigne: un outil de planification

La culture de la vigne dessine un paysage rural original. En effet, de par ses qualités physiologiques, ses exigences agronomiques et les techniques qu’elle requiert, elle est à l’origine d’un portrait de nature sculpté, architecturé, parfois même comparé à l’art des jardins. A ce que l’on pourrait le cas échéant qualifier d’« art involontaire »

French wine sector facing climate change (part. 1): A national strategy built on a foresight and participatory approach

A foresight study was carried out by a group of experts from INRAE, universities, INAO and FranceAgriMer from 2014 as part of the multidisciplinary “laccave” project intended to anticipate climate change in the French wine industry. The initial objective was to initiate an interdisciplinary dialogue between researchers and to feed their questions in a more systemic way. The scenario development method made it possible to build possible futures for the wine sector in the face of climate change. It began by drafting four adaptation strategies, combining different possible intensities of innovation and relocation of the vineyard.
