Try suggesting a plausible taste NOT PRESENT and record the result of other taster. A NOT PRESENT taste found is, of course, a false positive.

Try the test a number of times [say 10 independent sample events].

Report the result.

Of course, you might be labeled ‘the Chicken Little’ of beer notes not found.

Have other people test you with TRUE and FALSE taste present.
Record the results; report the results after a significant number of of test.

Or fall back to the binary taste test report
1 = this beer is awesome
0 = this beer sucks.
