Climat et sol: critères d’évaluation et effets sur le comportement de la vigne

Abstract

Le zonage viticole aborde en premier lieu la caractérisation des macroclimats aux échelles des grandes régions, pays, continents ou monde (géoviticulture). La méthodologie de caractérisation climatique et les premières applications au niveau des zones climatiques viticoles, sont présentés par Jorge Tonietto et Alain Carbonneau dans l’article du même ouvrage “Systèmes de Classification Climatique Multicritères (CCM) Géoviticole”, suite aux publications de Tonietto et Carbonneau, 1998a et 1999, et de Tonietto, 1999. Le présent article s’adresse aux échelles du terroir (interaction mésoclimat x sol/sous-sol), de la petite région ou de la parcelle.
Dans une première partie un rappel sera fait de l’influence du climat sur un cycle végétatif moyen de la vigne. Dans une seconde partie les méthodes de caractérisation des sols seront résumées, puis la méthodologie du bilan hydrique potentiel du sol sera approfondie. Dans une troisième partie, sur la base du réseau de terroirs pour le cépage Syrah dans le midi de la France, les principaux éléments de la typicité des vins seront mis en relation avec des variables du climat, du sol et du comportement de la vigne.

Physiological means to curb the enthusiasm of viruses from infecting grapevines  

The two most deadly viruses infecting and threatening the productivity of grapevines worldwide are leafroll and red blotch viruses. There is no cure for viral diseases other than roguing the symptomatic vines and replacing them with certified vines derived from clean, virus-tested stocks.
Given that phloem plays a central role in virus infection, this study aimed to purge the virus by girdling the phloem of leafroll-infected vines at different phenological stages of infected grapevines. Phloem-girdling was performed on canes at veraison to varying regions between the proximal and distal clusters.

SENSORY PROPERTIES IMPORTANT TO AUSTRALIAN FINE WINE CONSUMER SEGMENT PERCEPTION OF CHARDONNAY WINE COMPLEXITY AND PREFERENCE

Wine complexity is considered a multidimensional yet equivocal sensory percept. This project uncovered sensory attributes Australian Chardonnay wine consumers associate with Chardonnay wine complexity
and correlations between expert and consumer perceived wine complexity and preference. A
wine consumer test examined 6 Australian Chardonnay wines of three complexity levels designated low (LC1&2), medium (MC1&2), and high (HC1&2) by an expert panel (n = 8) using a benchtop sensory task. Consumers (n = 81) rated their perceived liking using a 9-point hedonic scale; wine complexity with a 5-point scale anchored “low”, “low-medium”, “medium”, “medium-high”, and “high” and lastly, profiled the wines using Rate-All-That-Apply (RATA). Psychographic segmentation with the Fine Wine Instrument
(FWI) generated three segments; Wine Enthusiasts (WE n=29), Aspirants (ASP n=40) and No- Frills (NF n=12).
