Caractérisation et valorisation des terroirs de l’appellation d’origine contrôlée Puisseguin-Saint-Emilion

Abstract

Le terroir viticole, qui est la base de la délimitation des aires d’Appellation d’Origine Contrôlée, est une notion complexe dans laquelle sont en interaction la vigne, les facteurs naturels tels que le sol, le climat, ainsi que le facteur humain à travers les pratiques des viticulteurs. Le terroir conditionne la composition des raisins et ainsi la qualité et la typicité des vins qui en sont issus. Suite à la fusion du syndicat viticole de Puisseguin avec celui de Saint-Emilion pour former le Conseil des Vins de Saint-Emilion, et dans une démarche globale de connaissance et de valorisation de cette nouvelle entité géographique, une étude sur le secteur de l’AOC de Puisseguin a été menée. Une cartographie des sols au 1/25 000 décrivant les différentes unités pédologiques a été réalisée ainsi qu’une analyse du système de conduite. Dans chaque unité pédologique identifiée, une fosse a été décrite puis analysée, permettant de définir les principales caractéristiques agronomiques de ces sols. Des conseils adaptés à chaque unité sont proposés afin de mieux valoriser ces terroirs. Chaque viticulteur a ainsi pu bénéficier des résultats de cette étude à travers un manuel technique et des communications orales.

English version: Terroir which is the basis for the controlled origin of wines (“Appellation d’Origine Contrôlée”) is a very complex concept including the vine, climate, soil and human factors such as technical practices. Terroir plays a very important role in grape composition and in wine quality and typicity. Following to the merge of Puisseguin and Saint-Emilion winegrowers associations and in order to improve the knowledge and the valorization of this terroir, a study was carried out on the Puisseguin area. This study comprized an identification of pedological units through soil mapping at a scale of 1/25 000th and a survey of currently existing training systems. For each pedological unit, advices were formulated to improve terroir valorization. Moreover, every wine grower received these results through a technical manual and oral communications.

Pierce’s disease of grapevines, a new threat to the wine industry in Southern Europe

Pierce’s disease (PD) is considered a potential threat to european viticulture (EPPO a2 list of pathogens since 1981). In the usa, infections caused by the vector-borne bacterium xylella fastidiosa have caused recurrent damage to vineyards in California and the southeastern states. However, vineyards in Europe have remained free of PD until recently, when it was first detected on the island of Mallorca in 2017. The reasons for the absence of PD in continental Europe have not been convincingly explained.

Effect of row direction in the upper part of the hillside vineyard of Somló, Hungary

Hillside vineyards have a great potential to produce world class wines. The unique microclimate lead to the production of rich, flavory wines.

Exploring magnesium defficiency in Welschriesling grapevines: A multi-omics approach to address viticultural challenges

Magnesium (Mg) deficiency poses a significant challenge to viticulture, particularly affecting Welschriesling (WR), a key grape variety in Austrian and Central European vineyards.

Effect of different packaging materials on table grape quality preservation during cold storage

During cold storage, grapes undergo changes that affect their visual, mechanical, and organoleptic properties, potentially impacting quality and negatively influencing consumer acceptance. Key parameters include uniform color, crunchiness, and flesh consistency. We evaluated the influence of two distinct packaging methods on the chromatic characteristics, hardness, and pedicel detachment resistance of fourteen new seedless white and red grape varieties during cold storage. These factors are crucial for maintaining the quality of the product and extending its shelf-life. The novel grape varieties were obtained through a breeding program at CREA-VE of Turi, Southern Italy.

An innovative 21st century frost alert system for an age-old viticulture challenge

Damage during the budbreak period due to spring season frosts remains one of the most significant weather-related challenges to viticulture around the world. For example, in 2021, €2bn of estimated damage was reported in france while >50% of vineyards were badly affected in the UK in 2017.
