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.

Typicality of Rioja wines: identification of sensory profiles for the three subregions of DOCa Rioja

Within the DOCa Rioja three main production areas are differentiated: Rioja Alta (RA), Rioja Alavesa (RAv) and Rioja Oriental (RO). They are three diverse territories with particular characteristics that are claimed to give rise to differentiated profiles. The present work aims at evaluating the sensory diversity of young commercial red wines in these three subregions. Therefore 30 young red wines (mainly Tempranillo and vintage 2021), ten from each subregion, were sensory described following a non-verbal free sorting task and a verbal free comment task by 32 well-established Rioja winemakers.

Exploring grapevine water relations in the context of fruit growth at pre- and post-veraison

Climate change is increasing the frequency of water deficit in many grape-growing regions. Grapevine varieties differ in their stomatal behavior during water deficit, and their ability to regulate water potential under dry soil conditions is commonly differentiated using the concept of isohydricity. It remains unclear whether stomatal behavior, water potential regulation, and the resulting degree of isohydricity has a relationship with changes to fruit growth during water deficit. This study was conducted on four varieties (`Cabernet Franc`, `Semillon`, `Grenache`, and `Riesling`) subjected to both short-term, severe water deficit and long-term, moderate water deficit applied at both pre- and post-veraison.
