Influence de l’ensoleillement sur la composante aromatique des baies de raisin

Abstract

La Syrah est un raisin à expression aromatique faible. Ce cépage atypique en tant que fruit permet l’élaboration de vins de grande réputation pour lesquels la particularité aromatique joue un rôle important. L’arôme variétal est constitué de substances volatiles directement perceptibles par la muqueuse olfactive et de précurseurs d’arôme, dont les glycosides constituent une classe importante. Ces derniers, des molécules inodores, sont en effet susceptibles, lors de la vinification, de donner naissance à des composés volatils et odorants participant à l’arôme du vin. Dans les baies de raisin de nombreux cépages et en l’occurrence dans la Syrah, les teneurs en glycosides sont nettement supérieures à celles des constituants volatils libres (Gunata et al., 1985 et Parle et al., 1991), ce qui montre l’importance des glycosides en terme de potentiel aromatique. Les glycosides peuvent être classés, en fonction de leur aglycone, par familles distinguant ainsi les composés en C6, les alcools, les phénols, les terpénols, les C13-norisoprénoïdes…Ces derniers, d’un grand intérêt olfactif, ont été identifiés dans le raisin et le vin (Strauss et al., 1987; Abbott, 1989). Dans les vins de Syrah, souvent caractérisés par une note de violette, les C13-norisoprénoïdes doivent contribuer fortement à l’arôme. En effet, parmi les composés les plus connus de la famille des Ci3-norisoprénoïdes, la β-ionone présente cette odeur de violette. L’importance des C13-norisoprénoïdes du point de vue de leur diversité olfactive et de leur teneur dans la fraction glycosylée de Syrah, nous a conduit à nous intéresser à leurs précurseurs, les caroténoïdes (Enzeil, 1985 ; Williams et al, 1992 ; Winterhalter, 1993). La teneur en caroténoïdes, relativement importante dans les baies vertes, diminue au cours de la maturation des baies (Razungles et al., 1988), ce qui laisse supposer que les C13-norisoprénoïdes trouvés dans les vins sont issus de ce catabolisme (Marais et al., 1991 ; Razungles et al., 1993). Les C13-norisoprénoïdes ont en effet le comportement inverse puisqu’ils augmentent avec la maturation des baies. L’importance du climat et du millésime sur la teneur en caroténoïdes et en arômes dans les baies a été montrée (Razungles et al., 1987 ; Marais et al., 1991 ; 1992). Nous nous sommes plus particulièrement intéressés dans ce travail à l’influence de l’éclairement des baies.

Study and valorization of vineyards “terroirs” in the Val de Loire

Face à la concurrence mondiale, il est indispensable de s’orienter vers des vins de qualité, marqués par une typicité et une authenticité inimitables. Le terroir représente, pour une région donnée, un patrimoine unique et non reproductible, qui peut être valorisé à travers l’origine et les caractéristiques sensorielles du vin.

Effect of nitrogen content on fermentation kinetics and aroma profile of assyrtiko wine

Today, there is need to design, produce and label terroir wines, with unique organoleptic properties and more “attractive to consumers”. For this purpose, two Saccharomyces cerevisiae yeast strains (Sa and Sb) isolated during spontaneous fermentations were used for white wine production from the Assyrtiko grape of Santorini. A third commercial strain was used as control.

ePROSECCO: Historical, cultural, applied philosophy analysis and process, product and certification innovation, for the “sustainable original progress and promotion 4.1c” of a historic and famous territory and wine

According to the algorithm “A step back towards the future 4.1C”, (Cargnello,1986a, 1987d, 1988a.b, 1991, 1993, 1994b, 1995, 1999a.e, 2000b, 2007c, 2008a, 2009d, 2013; and according to the principles of “Charter of Sustainable Viticulture BIO‐MetaEthics 4.1CC” of GiESCO (Carbonneau and Cargnello, 2003 2015, 2017), the historical, applied philosophy and productive analysis connected to the innovations and to the “Certification of the Universal Holistic MetaEthical Sustainability 4.1C” “indexed new global production model 4.1C” has always been fundamental, especially for the “Prosecco Territory” and for the “Prosecco Wine” to design and implement their synergistic future “Sustainable and Certificable 4.1CC” according to the principles of the “Charter of Sustainable Viticulture BIO‐MetaEthics 4.1CC” by the GiESCO (Carbonneau and Cargnello, lc, Cargnello et Carbonneau, 2007, 2018), and of the Conegliano Campus 5.1C. (Cargnello, lc). Nowadays, people think that Prosecco is a wine from the Veneto Region (from Conegliano and Valdobbiadene in particular), while it comes from Friuli‐Venezia Giulia Region (in North Eastern Italy, such as Veneto) more precisely from “Prosecco” in the Municipality of Trieste (TS‐Italy), as documented in 1382 and in 1548, when Pier Andrea Mattioli, described “that ancient wine, which is born in Prosecco”, as a wine with the following characteristics “thin, clear, shiny, golden, odorous and pleasant to taste». In 1888 at the “Wine Fair” of Trieste there were the “Sparkling wine Prosecco” by Giovanni Balanc, by Giuseppe Klampferer and that one by Marino Luxa. In the 19th century, many expressed their appreciation for the “Prosecco” of Trieste. In order to implement intra and extra territorial and cross‐border relations, as well as, the “Certification of: Products, Companies, Territory, Bio‐MétaÉthique District 4.1C” of Prosecco, a series of activities and researches were conducted in 8 companies: 5 in the “Territory of Prosecco” (TS) in which the principles of “Charter of Sustainable Viticulture BIO‐MetaEthics 4.1CC” of GiESCO (Carbonneau and Cargnello, lc) have been successfully applied. In particolar: 1‐ new and original “Sustainable 4.1C global production model” developed also to prevent the problems caused by wild boar, roe deer, and birds while safeguarding their “psychophysical wellness”, as well as the “psychophysical wellness 4.1C” of the macro and micro flora and fauna, of the biodiversity, of the landscape, etc. (Cargnello, lc), 1.2‐ chemical weed control and “Non MetaEthics 4.1C” processing with the total grass growing of the ground without or with mowing, better if it is manual to protect grass, air and soil, 2‐ recovery of “Historic”: land, vineyards, vines, biodiversity, landscapes, productions, products, … , 3‐ production of the famous “Prosekar, also rosé, of Prosecco” and “Prosecco di Prosecco”, according to “A step back towards the future 4.1C” 4‐ to offer a deserved psychophysical well‐being to the “Prosecco Territory” and entrepreneurs. 

Developing and assessing different cordon establishment techniques for long-term vineyard management

Aim: The aim of this research is to quantify the impacts of different cordon establishment techniques on vine health and longevity. It is hypothesised that wrapping developing cordon arms tightly around the cordon wire will cause a constriction of the vascular system, becoming worse over time and disrupting the flow of water and nutrients.

Impact of aging on dimethyl sulfide (DMS) in Corvina and Corvinone wines

Amarone is an Italian red wine produced in the Valpolicella area, in north-eastern Italy. Due to its elaboration with withered grapes, Amarone is a rather unique example of dry red wine. However, there is very limited data so far concerning the volatile composition of commercial Amarone wines, which also undergo a cask aging of 2-4 years before release. The present work aims at characterizing the aroma composition of Amarone and to elucidate the relationships between chemical composition and sensory characters.
