applicazione dei metodi isotopici e dell’analisi sensoriale negli studi sull’origine dei vini

Abstract

Traceability of agro-alimentary products is very important to certify their origin. This work aimed to characterize wines obtained by the same cultivar (Nero d’Avola and Fiano) – grown in regions with different soil and climate conditions during three vintages (2003-2005) – employing isotopic analyses (NMR and IRMS) and sensory analyses. The effectiveness of stable isotopes ratios (D/H)1, 13C/12C and 18O/16O to assess the geographical origin of wines is affected by the natural variability of these parameters. Their usefulness in wine origin identification improves when they are used jointly. (D/H)1 and 18O/16O ratios depend on latitude but, in the meantime, 18O/16O is noticeably modified by the meteorological course during grape ripening. The most powerful ratios to discriminate between regions are (D/H)1 and 18O/16O (Versini and Monetti, 1996). The isotopic and the sensory analyses together allowed to distinguish wines from different regions.

Estudio de fertilidad en variedades blancas en Castilla-la Mancha

La adaptación de nuevas variedades a zonas de cultivo fuera de su área de origen presenta múltiples interrogantes. En Castilla-La Mancha se está produciendo en los últimos años una gran inquietud por la diversificación y la reconversión de variedades.

Weather classification over the Western Cape (February, 1996 – 2000) and viticultural implications in the Stellenbosch wine district

Une étude préliminaire des situations météorologiques journalières a été réalisée pour l’Afrique du Sud et pour les mois de février (période de maturation des raisins dans la Province occidentale du Cap), à l’image de la classification synoptique réalisée aux latitudes tempérées en France (Jones & Davis, 2000), afin d’étudier les relations entre le climat et la viticulture à des latitudes plus basses.

Non Saccharomyces wine yeasts: emerging trends and challenges in winemaking

In the past, the contribution of non-Saccharomyces yeasts in winemaking has always been considered negative for their limited enological attitude if compared with Saccharomyces cerevisiae. In recent decades there has been a reevaluation of the role of non-Saccharomyces wine yeasts especially when used in combination and in support with S. cerevisiae (mixed fermentation). In this regard, selected non-Saccharomyces yeasts could be profitable used to give distinctive features, to enhance flavor and aroma complexity and to reduce the ethanol content of wines. Further emerging trends in the use of these yeasts are related to their role as bioprotectants and producers of health promoters compounds.

The use of δ13C as an indicator of water use efficiency for the selection of drought tolerant grapevine varieties

In the context of climate change with increasing evaporative demand, understanding the water use behavior of different grapevine cultivars is of critical importance. Carbon isotope discrimination (δ13C) measurements in wine provide a precise and integrated assessment of the water status of the vines during the sugar accumulation period in grape berries. When collected over multiple vintages on different cultivars, δ13C measurements can also provide insights into the effects of genotype on water use efficiency.
