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.

Appliance of climate projections for climate change study in Serbian vineyard regions

Early development of potential wine styles for PIWI varieties in grapevine breeding

In a framework in which climate change is increasingly recognized as a critical global challenge, traditional viticulture must be reconsidered in order to provide better solutions for future needs [1].

NIR based sensometric approach for consumer preference evaluation

Climate change has had a global impact on grape production, and as a result, developing table grape varieties that can withstand climate-related threats has become a significant goal. However, it is equally important to ensure that these new grape varieties meet the preferences of consumers. To achieve this goal, a procedure has been developed that combines sensory analysis with spectroscopic data collected in the NIR region. Each sample was analyzed using both traditional analytical techniques and non-destructive NIR spectroscopy.

Wine ageing: Managing wood contact time.

Barrel ageing is a transformative process that alters a wine’s organoleptic properties and consequently its price. Even though it is considered beneficial mostly for red wines, ageing can also be used for white wines but for shorter time periods. Due to barrel costs, space requirements and the markets’ demands for fast release of each new vintage, new products such as oak chips or shavings have been developed to help minimize the time needed for the extraction of essential wood compounds.
