Comportement du cépage Mourvèdre dans l’aire d’Appellation d’Origine Contrôlée de Bandol

Abstract

L’Appellation d’Origine Contrôlée de Bandol couvre une superficie de 1365 ha dont 83 % sont plantés en vigne, la production annuelle étant de l’ordre de 40000 hl. Parmi les vins produits, on trouve essentiellement des rouges s’affïrmant avec le temps, mais aussi des rosés caractérisés par leur couleur pale, généralement orangée ; les blancs représentent une faible part de la production. Le cépage principal de cette A.O.C. est le Mouvèdre, d’origine espagnole, que l’on retrouve aussi en Provence et Languedoc. En fonction des exigences spécifiques de ce cépage, nous avons déterminé différents terroirs ; des parcelles caractéristiques de chacun d’eux ont été suivies par analyses physico-chimiques des sols et des sous-sols et par diagnostics foliaires durant plusieurs années. Ces analyses avaient pour but de pouvoir proposer une fertilisation adaptée à chaque terroir afin de favoriser l’obtention de raisins et de vins de qualité.

Influence of soil type and changes in soil solution chemistry on vine growth parameters and grape and wine quality in a central coast California vineyard

The objective of this study was to determine the influence of four soils with contrasting chemical and physical properties on vine growth parameters and wine chemistry in a Paso Robles, California Cabernet Sauvignon vineyard

Changes in white wine composition after treatment with cationic exchange resin: impact on wine oxidation after 8 years of bottle storage

Samples from 3 wine types were treated with a cationic exchange resin (7 lots) and stored for 8 years (47 samples). Forty-seven parameters were determined, including (1) important substrates with impact in white wine oxidation and (2) markers of oxidation. From group 1, sugars, elements, phenolic compounds, α-dicarbonyls and SO2 and from group 2, browning (A420), acetaldehyde, alkanals, furanic compounds were quantified.

Deciphering grapevine trunk early molecular responses to P. minimum and P. chlamydospora in the presence of a commercial biocontrol agent (Trichoderma atroviride, Vintec®)

Esca, one of the main grapevine trunk diseases, is a complex and poorly understood disease. Phaeoacremonium minimum and Phaeomoniella chlamydospora, two of the main pathogens associated to this disease, are thought to be responsible for the first trunk infections. Little is known concerning grapevine trunk defenses during pathogen infection.

Sustainable management of grapevine trunk diseases

Grapevine trunk diseases (GTD) occur wherever grapes are grown and are considered the main biotic factor reducing yields and shortening vineyards’ lifespan. Currently, no product is available to eradicate GTD once grapevines are infected. Therefore, prophylactic strategies based on pruning wound protection and ‘remedial surgery’, the only eradication method based on the elimination of infected wood and renewal of the vine by means of new canes or suckers, are the only effective strategies available. The Canadian grape and wine industry focusses on a sustainable production and thus, looking for alternatives to chemicals for disease management is a top priority.

Crop load management of newly planted Pinot gris grown in warm climate of California

San Joaquin Valley accounts for 68% of Pinot gris acreage and produces 83% of Pinot gris wine in California. Strong demand for Pinot gris has prompted growers to restrict the nonbearing period
