Evaluate the fl avor of diluted apple juice samples with added acid, tannin, and caffeine and record results in Results Table 1. Be sure to taste each in turn against the control product (diluted apple juice) and against each other. Block your nose, to focus your attention on sensations throughout the mouth, and cleanse your palate between samples using water and unsalted crackers. Go back and retaste samples as often as needed, and focus on the following:

• What is perceived (puckering, salivating, drying, general unpleasantness, etc.) other than sweetness and aroma. • When (how quickly) sensation is perceived (immediately, slowly, as an aftertaste, etc.).

• Name other foods with this sensation (unsweetened chocolate, Sour Patch Kids candy, strong black tea, etc.).
