Conservation: the best valorisation strategy for wine growing areas

Abstract

Terroir encompasses many elements, including environment, grapes and human inputs that together contribute to the final wine quality of a certain wine growing area.

From the actual market situation, a clear trend has being emerging in the last years: only a small part of the total wine demand is oriented to high quality wines, the consumer being more oriented towards the medium-low cost wines. Thus, on one side there are the ancient and prominent winegrowing areas yielding high quality wines, where any aspect of the terroir (soil, climate, autochtonous varieties, tradition, landscape) must be valorised. On the other one, there is a new viticulture model spreading in less renowned areas where the traditions are not so deep-seated and where mechanical vineyard management is prevalent.

Considering the evident difference between these two terroirs, it becomes necessary to identify the key elements for each of them and to define their relative significance on wine global quality.
The preservation and valorisation of each single terroir component is the first step to best promote both these viticultures an their products.

Salubrity of environment and zoning process: first consideration on the radioactivity of vineyard soils

La salubrité du milieu et des aliments intervient de plus en plus lourdement, et souvent négativement, sur la santé de l’homme, aussi bien sur l’individu que sur la société tout entière.

Effect of grape harvest time on the metabolomic profile of ribolla gialla monovarietal sparkling wines

The timing of grape harvest is crucial factor to be considered in the winemaking process, as delayed harvest increases the content of varietal aromas, esters, aldehydes

Can soil nitrate explain polyphenol and anthocyanin content in vineyard with similar available soil water regime? 

Nitrogen (N) is quite important nutrient in grapevine development and must quality, but under Mediterranean climatic conditions, available soil water (ASW) during grapevine development can also influence vigour and must quality. The aim was to determine the influence of soil nitrate (NO3-) availability on N foliar, yield, and must quality in vineyards with similar available water holding capacity (AWC). For this purpose, four cv. Tempranillo (Vitis vinifera L.) vineyards were selected. All of them are placed in Uruñuela municipality (La Rioja, Spain), separated less than 2.5 km and in a slope <1 %, in soils with similar soil chemistry properties and with similar rooting depth (ranging between 105 cm and 110 cm).

Use of glutathione under different grape processing and winemaking conditions and its impact on the formation of sulfide off-flavors, colour, and sensory characteristics of Riesling, Sauvignon blanc, and Chardonnay

The use of glutathione (GSH) in winemaking has been legitimated recently, according to OIV resolutions OENO 445-2015 and OENO 446-2015 a maximum dose of 20 mg/L is now allowed to use in must and wine. Several studies have proven the benefits of GSH, predominantly in Sauvignon blanc. Thus, oxidative coloration of must and wine is limited, aroma compounds such as volatile thiols are preserved, and the development of ageing flavors such as sotolon and 2-aminoacetophenone is impeded. The protective effect may be explained by the high affinity of GSH to bind o-quinones which are formed during phenolic oxidation and which are known to initiate browning and other oxidative changes. Some researchers have proposed the hydroxycinnamic acid to GSH ratio (HGR) as an indicator of oxidation susceptibility of must and could show that lower ratios yielded lighter musts.
