Vineyards and grape varieties: what is going on in wine professional and consumer minds?

Abstract

Vineyard and grape variety are two popular ways of classifying wines. Vineyard designation is a traditional practice for European wine labels but is being increasingly replaced by grape variety designation, mainly used for New World and Swiss wine labels.

In a context of wine categorization, we investigated on the relationship between those two dimensions. For this purpose, we selected a set of 56 wine labels to represent three red grape varieties (Gamay, Pinot Noir and Gamaret) and three vineyards (Beaujolais, Burgundy and Switzerland). Three panels were recruited: a panel of 30 wine professionals (experts) from the Beaujolais vineyard, a panel of 30 wine consumers from the Beaujolais vineyard and a panel of 30 wine consumers from Lille, a French region without wine production. We used a free hierarchical sorting task on labels coupled with a verbalization task and an interview. Data were first analyzed separately for each panel using a Hierarchical Multiple Factor Analysis and a Hierarchical Ascending Classification.

Results showed that the three panels yielded very similar wine groups. With the exception of Gamaret wines, most French wines were separated by both vineyard and grape variety while Swiss wines were separated by grape varieties. Despite this similar categorization pattern, the interviews revealed different sorting criteria and strategies used to sort the labels for each panel. With the exception of a small part of experts, both experts and consumers from Beaujolais used their knowledge of grape varieties and vineyards to sort the wine labels while the consumers from Lille simply read the labels to find clues and deduce wine groups, because of a lack of knowledge.

Overall, the results indicate an interaction between vineyard and grape variety dimensions for the wine categorization by experts and consumers. The methodology proposed seems to be a promising tool that could be helpful to improve the promotion of wines.

EXTRACTIBLE COMPOUNDS FROM MICROAGGLOMERATED CORK STOPPERS

After bottling, the wine continues to evolve during storage. The choice of the stopper is an important factor in this evolution. In addition to the oxygen permeability of the closure, the migration of stopper compounds into the wine can also have an impact on the wine organoleptic properties. Many studies have shown that transfers of volatile compounds from the stoppers into the wine can happen depending on the type of closure used (1). Moreover, when cork-made stoppers are used, the migration of phenolic compounds from the stopper into the wine can also occur (2, 3).

Effect of pre-fermentative cold soaking and use of different enzymes on the chemical and sensory properties of Catarratto wines

The wine industry widely recognizes that early-harvested grapes or those with uneven ripeness at harvest can produce wines with an “unripe fruit” mouthfeel [1,2]. Despite this, it is still unknown which compounds cause these sensory flaws or the most effective winemaking techniques to address them.

Development of analytical sampling technique to study the aroma profile of Pinot Noir wine

A novel and efficient Dispersive Liquid-Liquid Microextraction (DLLME) method coupled with gas chromatography–mass spectrometry (GC–MS) was developed to determine 33 key aroma compounds (esters, alcohols, aldehydes, terpenes, norisoprenoids, fatty acids and phenols) present in Pinot noir (PN) wine. Four critical parameters including extraction solvent type, disperse solvent type, extraction solvent volume and disperse solvent volume were optimised with the aid of D-optimal design.

Characterizing graft union formation in different scion/rootstock combinations of grapevine 

In most viticultural regions, grapevines are cultivated grafted, employing either hybrid or pure species of various American Vitis spp., such as V. berlandieri, V. rupestris, and V. riparia, as grapevine rootstocks. These rootstocks play a crucial role in providing resistance to the Phylloxera insect pest. Beyond Phylloxera resistance, it is desirable for grapevine rootstocks to exhibit resistance to other soil-borne pathogens and adaptability to abiotic stress conditions. The introduction of new rootstocks holds promise for adapting agriculture to climate change without altering the characteristics of the final harvested product.

Genomics and phenomics of root system architecture in grapevine

Adapting viticulture to climate change is crucial, as it presents significant challenges for future grape production.
