Incidence de la nature du sol et du cépage sur la maturation du raisin, à Saint Emilion, en 1995

Abstract

L’A.O.C. Saint-Emilion, une des plus prestigieuses du Bordelais, se situe sur la rive droite de la Dordogne en amont de Libourne. Le vignoble est implanté sur des formations géologiques du Tertiaire (Oligocène) et du Quaternaire, sur lesquelles se sont développés des sols très variés. De nombreuses études ont rendu compte de cette hétérogénéité et permis de mieux connaître le fonctionnement et les potentialités viticoles de ces sols (Duteau et al. 1981, Van Leeuwen, 1991).

Dans ce travail, nous avons étudié le comportement des deux principaux cépages noirs de la région, le Cabemet franc et le Merlot noir, sur trois sols : un sol graveleux (G), un sol à sous-sol très argileux (A) et un sol sableux avec une nappe d’eau à portée des racines (S). L’objectif a été de mieux connaître les interactions entre le sol et le cépage, afin de valoriser au maximum les potentialités du terroir par une adaptation judicieuse du cépage au type de sol. Nous présentons ici les résultats obtenus au cours du millésime 1995, qui seront comparés avec ceux obtenus en 1994.

NOVEL BENZENETHIOLS WITH PHENOLS CAUSE ASHY, SMOKE FLAVOR PERCEPTION IN RED WINES

Smoke impacts on wines are becoming a worldwide problem; the size and severity of wildfires increasing due to influences from changing climates.¹ For over a century, wines have been known to have a unique issue of absorbing chemical compounds derived from wildfire smoke wherein the flavor of the subsequent wine becomes ashy, rubbery, campfire-like, and smoky.² The economic impacts of a smoke-impacted wine can last for years depending on the grape varietal, costing Oregon and Washington states in the United States over a billion dollars from the 2020 wildfires, as an example.³ While years of research have indicated elevated concentrations of smoke-related compounds, such as guaiacol and syringol, in wines after smoke events, unfortunately, replicating the sensory experience using smoke-associated phenols has not had much success.⁴

Geochemistry of Vrbničko Polje (Croatia) winegrowing site

A multi-element pedo-geochemical survey was carried out in Vrbničko polje vineyards on the Krk Island, Croatia. This Mediterranean winegrowing site is famous by Žlahtina wine production.

Effect on the grape and wine characteristics of cv. Tempranillo at 3 production levels

The vineyard has experienced a general increase in yields mainly due to the elevated use of technology which caused a quality loss of grapes in more than one case. A large percentage of the Spanish vineyard is covered by a Denomination of Origin which limits the productive level of the vineyards as one of its regulations. The maximum production limit is a variable characteristic of each vineyard and is not usually regulated by agronomic criteria, and this explains the fact that each vineyard can reach high quality with a totally different yield from that set by the Denomination of Origin.

What is the best time to harvest grapes destined for withering? Ripeness and dehydration length affect phenolic composition of Nebbiolo grapes

Sfursat di Valtellina is a DOCG reinforced wine produced in Valtellina from partially withered red grapes of Vitis vinifera L. cv. Nebbiolo. The grape ripeness degree and the dehydration process strongly influence the physicochemical characteristics of grapes [1, 2, 3]. In particular, grape skin and seeds contain several classes of phenolic compounds strictly associated with red wine quality, which are significantly affected by these factors [4]. The aim of this research is to assess the combined influence of different ripeness levels and withering rates on the standard chemical composition and phenolic profile of winegrape in order to provide new insights and approaches to the management of withering, searching for the valorization of grape potentialities.
