Smell accounts for what % of taste?

• A. 50%
• B. 85%
• C. 65%
• D. 95%

Answer: (B)

Smell's contribution to flavor perception is the idea being tested. While basic tastes—sweet, sour, salty, bitter, and umami—come from taste buds, most of what we experience as flavor comes from aroma. When we chew and swallow, volatile compounds travel up the back of the throat into the nasal cavity (retronasal olfaction), so smell largely shapes flavor. Because of this, smell accounts for about 85% of what we perceive as taste. That 85% figure is the commonly cited amount, making it the best choice among the options. The other percentages don’t align with how aroma drives flavor in tasting.
