Impact of harvest date on the terroir expression and the aroma profile of Touraine Sauvignon wines

Abstract

[English version below]

L’objectif d’une étude sur trois années vise, pour des terroirs différents et connus pour le profil des vins qui en sont issus, à exploiter au mieux le potentiel des raisins en optimisant la date de récolte ; pour chacun des trois terroirs, les minivinifications sont réalisées à partir de trois dates de récolte . Il s’avère, grâce à un suivi analytique important (sol, précurseurs et arômes) et une caractérisation organoleptique bien encadrée (analyse sensorielle pertinente et objective), que le choix de la date de récolte, en fonction du terroir, a une incidence sur le profil du vin et devient un outil pour l’élaborateur. Cela se traduit sur le caractère variétal (cassis, fruits exotiques, agrumes) du vin.

The aim of this three year study is to maximize the revelation of the grapes’ potential by optimizing the harvest dates for different terroirs known for the wine profiles that they produce. For each of these terroirs, mini-vinifications were done from grapes of three harvest dates. A large-scale analytical follow-up (earth, aroma precursors and aromas) and a strictly framed organoleptic characterisation (pertinent and objective sensory analysis) are adopted. All showes that the choice in the harvest date, according to the terroir, has an impact on the wine profile and therefore can become a tool for wine-makers. This effect influences the wines’ varietal character: blackcurrant, exotic and citrus fruits.

Development and application of CRISPR/Cas in grapevine

The development and application of CRISPR (clustered regularly interspaced short palindromic repeats)/Cas (CRISPR-associated protein) technologies have revolutionized genome editing in plants due to its simplicity, high efficiency, and versatility. As an economically important fruit crop worldwide, grapevine genome editing using CRISPR/Cas technologies has also been reported these years. Here we introduce the development briefly of the most popular CRISPR/Cas9 system and also the state-of-the-art CRISPR technologies developed so far. Moreover, we summarize CRISPR/Cas9-mediated applications for gene functional study and trait improvement in grapevine.

Methodology to assess vine cultivation suitability using climatic ranges for key physiological processes: results for three South African regions

Le climat a de fortes implications sur le bon fonctionnement physiologique de la vigne et a besoin d’être quantifié afin de déterminer l’aptitude des régions à la culture de la vigne. Une méthode, qui pourrait éventuellement servir à prévoir l’aptitude des régions à la culture de la vigne, est proposée.

Analysing consumers’ decision-making process for non-alcoholic spirit drinks and dehalcolized aromatized wines 

In recent years, the consumption of alcoholic beverages is changing, driven by evolving consumer preferences and societal trends, including a wave of health consciousness. Among these changes, the emergence and proliferation of nolo (no alcohol/low alcohol) alcoholic beverages have gained significant attention within the industry. Nolo alcohol beverages are produced to emulate the appearance, aroma, and taste of alcoholic beverages, potentially facilitating a sense of social integration when consuming a product that closely resembles alcohol.

Does bioprotection by adding yeasts present antioxydant properties?

AIM: The bioprotection by adding yeasts is an emerging sulfur dioxide alternative. Sulfur dioxide is a chemical adjuvant used for its antiseptic, antioxidasic and antioxidant properties. Faced with the societal demand (Pérès et al., 2018) and considering the proven human risks associated with the total doses of sulfur dioxide (SO2) present in food requirements (García‐Gavín et al., 2012), the reduction of this chemical input is undeniable.
