Good for explanation, but the exact proportion of smell in any whiskey experience should not be reduced to a universal percentage.
The passage introduces the ordinary-language confusion between taste and flavor.

Paraphrase of PDF sheets 10–11: a nose-blocking candy comparison illustrates smell's contribution and the ambiguity between everyday taste and flavor.
Location and context
Introduction, PDF sheets 10–11. The existing sheet-11 locator identifies the explanation; the demonstration begins on sheet 10.
Annotation
This is an illustrative contrast, not a universal numerical allocation of flavor to smell. Compare the author's explicit qualification on sheets 18–20. Do not repeat its categorical least-important-taste phrasing as a scientific ranking.
