Whisky is an alcoholic distillate obtained from different cereals, whose characteristics are related to the region of origin, where the climatic conditions, the raw materials and the production technology determine their sensory characteristics. In order to develop a sensory vocabulary useful as a tool to improve communication between experts and consumers, the sensory profile and the aroma compounds of eight brands of whisky (four Scottish, three American and one Irish) were determined. The ANOVA results showed that the samples differ for the descriptors: color and acid, for the alcohol, cooked and aged aromas, and for the smoked, spicy and wood flavours. Differences between the samples were also found in the content of aromatic molecules such as higher alcohol, phenols, carbonyl compounds, acetals, acetates and terpenes.
Il whisky è un distillato alcolico ottenuto da diversi cereali, le cui caratteristiche sono legate alla regione di origine, dove le condizioni climatiche, le materie prime e la tecnologia di produzione determinano la loro impronta sensoriale. Allo scopo di sviluppare un vocabolario sensoriale oggettivo da usare come strumento per migliorare la comunicazione tra esperti e consumatori, sono stati determinati il profilo aromatico e sensoriale di otto marche di whisky (quattro scozzesi, tre americani ed uno irlandese). Dai risultati dell’ANOVA è emerso che i campioni differiscono per i descrittori: colore e acido, per gli aromi alcool, cotto, invecchiato e per i flavour di affumicato, speziato e legno. Differenze tra i campioni si sono riscontrate anche nel contenuto di molecole aromatiche quali alcoli superiori, fenoli, composti carbonilici, acetali, acetati e terpeni.

Abstract
Whisky is an alcoholic distillate obtained from different cereals, whose characteristics are related to the region of origin, where the climatic conditions, the raw materials and the production technology determine their sensory characteristics. In order to develop a sensory vocabulary useful as a tool to improve communication between experts and consumers, the sensory profile and the aroma compounds of eight brands of whisky (four Scottish, three American and one Irish) were determined. The ANOVA results showed that the samples differ for the descriptors: color and acid, for the alcohol, cooked and aged aromas, and for the smoked, spicy and wood flavours. Differences between the samples were also found in the content of aromatic molecules such as higher alcohol, phenols, carbonyl compounds, acetals, acetates and terpenes.File | Dimensione | Formato | |
