Resumen
The sensory profile of 23 monovarietal Malbec wines were evaluated and related to the headspace composition of aroma at two alcohol levels (I0.0-I2.0 to 14.5-17.2% v/v). Twelve attributes were selected by quantitative descriptive analysis. At P < 0.01, two attributes showed lower aromatic intensity when alcohol level increased, and at P < 0.05, three attributes showed lower intensity; only one attribute showed higher intensity (P < 0.05). Seventeen aroma compounds were identified using solid-phase microextraction gas chromatography. Only one identified aroma compound showed lower contribution when alcohol level increased (P < 0.01); another aroma was added at P < 0.05. Only one aroma showed higher contribution (P < 0.05). Ethanol influenced the relative contribution of aroma compounds in different way - some declined while others increased. The sensorial aroma perception was also changed; when ethanol was at I4.5-I7.2%, the odor was described as herbaceous instead of fruity, as was perceived at low ethanol levels. © 2009, Wiley Periodicals, Inc.
