Valorisation agroviticole de l’effet terroir par l’enherbement des sols

Abstract

Les études développées par l’INRA et l’UV, à Angers, concerne les terroirs viticoles et leur gestion optimisée, tant du point de vue agroviticole qu’oenologique. Les travaux antérieurs (Morlat, 1989) ont permis de donner une dimension scientifique au concept de terroir viticole et ont démontré l’influence considérable de ce facteur de production sur la qualité et la typicité des vins (Asselin et al, 1992). Une méthodologie de caractérisation intégrée des terroirs, s’appuyant sur « l’Unité Naturelle Terroir de Base » (considérée comme la plus petite unité spatiale de territoire utilisable dans la pratique, et dans laquelle la réponse de la vigne est homogène), a été mise au point (Riou et al, 1995).

Les terroirs identifiés et cartographiés selon cette méthode occupent une surface qui varie de quelques hectares à plusieurs centaines d’hectares. Ils peuvent constituer la base d’un zonage pour une région viticole, à partir duquel on peut envisager d’une part, une utilisation rationnelle de l’effet terroir à l’échelle de l’exploitation viticole, et d’autre part une gestion parcellaire des itinéraires techniques.

la caratterizzazione dell’areale viticolo “terre alte di brisighella”: aspetti metodologici e primi risultati

La zonazione viticola rappresenta un importante strumento di indagine per valutare e interpretare le potenzialità produttive e qualitative di un territorio. Con l’obiettivo di studiare come l’ambiente influisca sulla qualità dell’uva nell’areale di Brisighella, sono stati monitorati, nelle annate 2007, 2008 e 2009, 14 vigneti per la varietà Albana e 38 per la varietà Sangiovese, rappresentativi di una area vitata di circa 1000 ha.

Effects of grapevine mycorrhizal association on fine root dynamics depend on rootstock genotype

Context and Purpose of the study. Arbuscular mycorrhizal fungi (AMF) symbiosis with grapevines is a key component of vineyard ecosystems.

Validating a portable ad-hoc fluorescence spectrometer for monitoring phenolic compounds during wine fermentation

Phenolic compounds are fundamental to wine quality, influencing its colour, mouthfeel, stability, and ageing
potential [1]. Their extraction and evolution during fermentation plays a crucial role in determining the final sensory
attributes and requires careful monitoring to guide winemaking decisions.

Monitoring the tawny port wine aging process using precision enology

AIM: Tawny Port wine is produced in the Douro Demarcated Region by blending several fortified wines in different aging stages. During the aging process in small wood barrels, the red wine color progressively develops into tawny, medium tawny, or light tawny.

Comparative study of qualitative and quantitative characters of grape cultivar ‘Mavrodafni’ (Vitis vinifera L.) grown in different regions of the PDO Mavrodafni Patras

‘Mavrodafni’ (Vitis vinifera L.) is considered one of the oldest grapevine cultivars indigenous to the Greek vineyard, with western Peloponnese being its primary center of cultivation. ‘Renio’ is considered to be either a variant of ‘Mavrodafni’ or an altogether different cultivar. Both ‘Mavrodafni’ and ‘Renio’ can be found in the vineyards of the centers of cultivation, since ‘Renio’ is considered to be more productive compared to ‘Mavrodafni’, and for this reason, it has gradually replaced ‘Mavrodafni’ from cultivation over the course of time. The aim of the present study was to assay the mechanical properties, the polyphenolic content and the antioxidant capacity of skin extracts and must of berries coming from ‘Mavrodafni’ and ‘Renio’, cultivated in the same vineyard as well as in the different regions of cultivation of the PDO Mavrodafni Patras.
