Tonic water is a soda characterized by a bitter taste attributed to quinine. The objective of this work was to evaluate the acceptance and the perception of the bitter taste of three commercial brands of tonic water. For the acceptance test, a hedonic scale of nine points and ninety six consumers were used. This attribute was also analyzed using the Time-intensity technique. Nine individuals, selected as panelists, evaluated the samples of tonic water using the program "System of Collection of Data Time-intensity-SCDTI" for Windows. The obtained results were analyzed by the Analysis of Variance (ANOVA) and Duncan's test. The brands of tonic water showed differences in Time-intensity curves for the bitter taste. The samples showed no difference regarding the intensity of the bitter taste in the Time-intensity's analysis. The M-1 and M-2 samples were better graded than M-3.
