Methodological comparison, not proof that the methods are equivalent or that consumer proof normalization follows the same protocol.
Lahne and Cadwallader, chapter3; abstract PDF41, methods50–51, comparison52–54. AEDA used a concentrated extract; SDA used the beverage diluted with ethanol.
In one 40% ABV añejo tequila, direct-injection sample dilution analysis and extraction-based AEDA overlapped on prominent odorants, but SDA missed more odor peaks and had lower dilution resolution. The authors recommend further sensory validation.
