Typicality related to terroir: from conceptual to perceptual representation: study of the links with enological practices

Abstract

The conceptual image of a wine related to the terroir has consequences in technical terms. Among factors affecting the typicality, producers put forward the environmental factors of the terroir system, then the variety and finally the viticultural and oenological factors. We postulate that for the production of red wine, the “phenolic maturity” must be considered as an essential criterion. The “phenolic maturity” was translated into the date of grape harvest and the duration of vatting. Because of the nature of the corresponding biochemical compounds, these choices could have important consequences on the sensory profile of wines. The objective of this study is to understand the relationship between the conceptual image of a wine and the perceptual dimension of the wine, by connecting the typicality with some technical acts. The distinctive French wine style “Anjou Village Brissac” was investigated through four methods. A survey was performed to measure the conceptual dimension, and three sensorial methods were used for the perceptual dimension (Quantitative descriptive analysis (QDA) by a sensory expert panel, Just About Right analysis (JAR) by wine experts, and assessment of the typicality by wine experts). Wine experts were producers, winemakers, and oenologists from the area. The survey allowed highlighting soil as the first factor that affects the typicality. On the other hand, the QDA and JAR profiles highlighted the prevalence of the technical factors, in particular oenological, over the environmental factors. The JAR profile allowed to classify attributes in the typicality scores. Moreover, the study made it possible to show the shift between the conceptual typicality and the perceptual typicality, from the point of view of the technical acts, but also from the sensory point of view.

Application of viticulture zoning in Istria (Croatia) as important element for valorization of all territory resources (product, environment, tourism and others)

Un projet touristique innovant est en cours dans la zone historique croate d’Istrie Centrale, autour de la magnifique ville de Motovun. L’approche méthodologique repose sur le concept de «Système Productif-Global du Territoire» et s’appuie tout particulièrement sur celui de « Zonage Vitivinicole ». Elle tient compte de toutes les facettes, définies dans celui de « Grand Zonage » (Cargnello G., 1999).

Influence of agronomic practices in soil water content in mid-mountain vineyards

In the context of LIFE project MIDMACC (LIFE18 CCA/ES/001099), several pilots have been installed in vineyards in mid mountain areas of Catalonia (NE Spain) to test well stablished agronomic practices to increase the adaptation of Mediterranean mid mountain to climate change. Soil water content (SWC) at three different depths (15, 30 and 45cm) was measured in continuum from August 2020. One pilot (WC) included a well-established green cover (GC), a new GC (NC) and a conventional soil management (CM, tilling+herbicides). NC presented an intermediate state between WC and CM, responding similarly to CM in autumn but quickly reaching similar SWC to WC, then following the same evolution till next spring, with CM presenting lower values along autumn and winter. Then vegetation activation decreased SWC in all plots, (much slower in CM, lacking GC). Sensibility to spring rains is again intermediate for NC, which joins SWC evolution of CM by the end of spring till next autumn. It is expected that NC will resemble WC more and more as its GC develops. In the pilot combining vine training (VSP vs Gobelet) and hillside management (slope vs terrace), no clear pattern could be related with these conditions. However, both terraces seem to be more sensitive to spring rains. A third pilot included new vineyards (7 and 1 year old). In the new vineyard (N), higher canopy development, a spontaneous green cover and row straw resulted in a slower SWC dynamic, not so sensitive to rains but conserving more soil water in spring and most of summer, even with presumably a higher water extraction by vines. In the newest vineyard (VN) the deepest sensor is still sensitive to rain events all over the year and SWC is always highest at this depth, revealing small water capture by vines.

Evaluation of the efficiency of dialysis membranes in the wine dealcoholization process

The global wine production is continuously evolving to meet the new demands and preferences of consumers. in this evolving scenario, it’s important to determine which trends will be short-lived and which will remain over time. The promotion of healthier habits has encouraged consumers to try to find alternatives with low or no alcohol content. The challenge for the industry is to produce an alcohol-free wine that retains the familiar aromas and mouthfeel of traditional wine but without alcohol. Ethanol is the most abundant compound in wine, excluding water.
