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.

Comparison between the volatile chemical profile of two different blends for PDO “Valpolicella Superiore”

Valpolicella is a famous wine producing region located in the north of Verona close to Garda lake and owes its fame above all to the production of two Protected Designation of Origins (PDOs) withered wines: Amarone and Recioto. Nowadays the production of another PDO, Valpolicella Superiore is gaining more attention by the consumers, increasing the interest of the wineries to improve the quality of this wines

Ageing of sweet wines: oxygen evolution according to bung and barrel type

Barrel ageing is a crucial step in the wine process because it allows many changes to the wine as enrichment, colour stabilization, clarification and also a slow oxygenation. Effects of the oak barrel have to be known to prevent oxidation of the wine. The type of bung used during ageing is also a parameter to consider. Ageing sweet wines in barrel is a real challenge. These wines may need some oxygen at the beginning of ageing but they should be protected at the end of their maturation, to avoid oxidation.

High throughput winter pruning weight estimation based on wood volume evaluation 

There is currently a real need to improve and speed-up phenotyping in experimental set-ups to increase the number of modalities studied. Accurate information acquisition on plant status with high-throughput capacity is the main appeal of on-board systems.
A proximal sensing camera for a proxy of winter pruning weight was tested. We estimated the shoot volume of the vine by image analysis using algorithms that integrate the local shoot section area estimate along the shoot skeleton obtained by a morphological distance transform.
The study was carried out on the GreffAdapt experimental vineyard in Guyot simple training and a canopy management using vertical trellising. The planting density is 6250 vines/ha with a row spacing of 1.6×1m. Five scions grafted onto 55 rootstocks are present and the combination rootstock×scion is different every five plants.
