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

Abstract

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.

Eight commercial wines were sourced from regions across the United States, including five non-vinifera monovarietal wines (Corot noir, Maréchal Foch, Marquette, Norton, and St. Croix) and three Pinot noirs from France, Oregon, and New York. The selection of Pinot noir from three representative regions was to create a context of a Vitis vinifera cultivar with a unique anthocyanin profile. The eight wines were used in a consumer perception sensory analysis, where red wine consumers reported hedonic liking for a selection of color parameters as well as ‘expected liking’ prior to tasting the wine and ‘actual liking’ following in-mouth evaluation. Chemical analyses of these eight wines and eleven other non-vinifera wines included UV-Vis spectrophotometry, CIEL*a*b* colorimetry, and anthocyanin analysis via high-pressure liquid chromatography (HPLC) and mass spectrometry (MS).

For all color parameters, the wines ranked highest for liking included Maréchal Foch, St. Croix, and the Pinot noirs from France and Oregon. Wines with higher L* values (lighter color) and higher b* values (more brown hues), including Corot noir, Norton, and Pinot noir from New York, were less liked than darker wines with less brown hues. Notably, panelists reported that quality expectations formed from visual inspection did not match their actual liking of the wine.

Interestingly, this work suggests that color is only a weak predictor for actual liking of a wine. Furthermore, it is possible that the potential diversity of color from interspecific hybrid wines falls within the range of colors of the different cultivars and styles of wine produced around the world, allowing further research to move away from the goal of “vinifera-like” color in optimizing interspecific red wine production.

Microbial ecosystems in wineries – molecular interactions between species and modelling of population dynamics

Microbial ecosystems are primary drivers of viticultural, oenological and other cellar-related processes
such as wastewater treatment. Metagenomic datasets have broadly mapped the vast microbial species
diversity of many of the relevant ecological niches within the broader wine environment, from vineyard
soils to plants and grapes to fermentation. The data highlight that species identities and diversity
significantly impact agronomic performance of vineyards as well as wine quality, but the complexity
of these systems and of microbial growth dynamics has defeated attempts to offer actionable
tools to guide or predict specific outcomes of ecosystem-based interventions.

WINE RACKING IN THE WINERY AND THE USE OF INERT GASES: CONTROL AND OPTIMIZATION OF THE PROCESS

Atmospheric oxygen (O₂) generates oxidation in wines that affect their physicochemical and sensory evolution. The O₂ uptake in the different winemaking processes is generally considered to be negative for the sensory characteristics of white and rosé wines. Wine racking is a critical point of O₂ uptake, as the large surface area of the wine exposed during this operation and the inability to maintain an effective inert gas blanket over it.
The aim was to study the uptake of O₂ during the racking of a model wine as a reference and to compare with purging the destination tank with different inert gases.

ASSESSING THE ROLE OF 27 KNOWN BITTER COMPOUNDS IN COMMERCIAL WHITE WINES COMBINING LC-MS QUANTIFICATION AND SENSORY ANALYSIS

The balance between the different flavours of a wine largely determines its perception and appreciation by the consumers. In white wines, sweetness and sourness are usually the two poles balancing the taste properties. The bitter flavour, on the other hand, is frequently associated with a loss of equilibrium and all white wines (dry and sweet, young and aged) are affected.
Several bitter compounds are already well-described in wines.

VOLATILE AND GLYCOSYLATED MARKERS OF SMOKE IMPACT: LEVELS AND PATTERNS OBSERVED IN 2020 WINES FROM THE UNITED STATES WEST COAST

Smoke impact in wines is caused by a wide range of volatile phenols found in wildfire smoke. These compounds are absorbed and accumulate in berries, where they may also become glycosylated. Both volatile and glycosylated forms eventually end up in wine where they can cause off-flavors, described as “smoky”, “bacon”, “campfire” and “ashtray”, often long-lasting and lingering on the palate. In cases of large wildfire events, economic losses for all wine industry actors can be devastating.

IMPACT OF CLIMATIC CONDITIONS ON THE SEASONING QUALITY OF OAK WOOD FOR OENOLOGICAL USE (QUERCUS PETRAEA)

For coopers, seasoning and toasting are considered crucial steps in barrel making during which the oak wood develops specific organoleptic properties. Seasoning, carried out in the open air, allows reducing the moisture content of the staves to between 14 and 18% (compared to 70 to 90% after splitting) while modulating the intrinsic composition of the oak wood. Toasting consists of applying different degrees of heat to a barrel for a specific period of time. As the temperature increases, oak wood produces a wide range of chemical compounds through thermal degradation of its intrinsic composition.
