Two taste sensitivity measures (detection threshold and time‐intensity [T/I]) were applied to evaluate bitter taste sensitivity of caffeine in both caffeine nonusers (n = 12) and users (n=12, caffeine consumption level; > 300mg/day). Taste thresholds of caffeine were significantly different between nonusers and users in two test sessions (p < 0.01 in first and p < 0.05 in second). In T/I measures, only the difference in peak height was observed between the two groups in one of two test sessions. The other two measures, half width and area of T/I curves showed no significant difference.
