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.

Polyphenol content examination of Tokaji Aszú wines

We must state that two conditions above are only prevalent in the case when the processed grapes are full or over ripened, besides following the Tokaj wines preparation criterions (grape variety, soil, microclimate, vintage, etc.). These two conditions mentioned before were followed up only sensory based analysis up to now, altough the study of chemical idetified compounds which confirms these are obviuos.

Effects of long-term drought stress on soil microbial communities from a Syrah cultivar vineyard

Changes in the rainfall and temperature patterns affect the increase of drought periods becoming one of the major constraints to assure agricultural and crop resilience in the Mediterranean regions. Beside the adaptation of agricultural practices, also the microbial compartment associated to plants should be considered in the crop management. It is known that the microbial community change according to several factors such as soil composition, agricultural management system, plant variety and rootstock.
