If anyone's curious, there are actual tests for this. They're little strips of paper that look like litmus paper, but they're embedded with a test substance. You put it in your mouth for 5 seconds, and your reaction to the test substance gives you an idea of where you are on the tasting spectrum. Highly entertaining. We discovered that, of my household at the time, two people were supertasters, two people were normal tasters, and one person was a subtaster.
