Abstract

Sample dilution analysis (SDA) is a novel methodology for identifying key odorants in distilled alcoholic beverages by direct injection-gas chromatography-olfactometry (GCO). SDA has the potential to provide accurate key odorant identification with reduced analysis and material costs, while also reducing extraction bias. The methodology was applied to 100% agave añejo tequila, a spirit with distinct organoleptic qualities. Results from SDA and aroma extract dilution analysis (AEDA) were comparable, and identified 2/3-methyl-1-butanol, 2-phenylethanol, linalool, β-damascenone, guaiacol, 4-ethyl-guaiacol, eugenol, trans-isoeugenol, and vanillin as the key odorants of 100% agave añejo tequila.
