Acute Taste/Smell is one of Fallout GURPS advantages. See: Fallout GURPS.
You have better-than-average senses. Acute Taste/Smell gives you a bonus when rolling to notice a taste or smell. Acute Vision gives you a bonus when rolling to see something. Each acute sense is a separate advantage, and costs 2 points for every +1 bonus to your roll. E.g., Acute Hearing +6 costs 12 points.”— Steve Jackson Games GURPS sources
With the abandonment of GURPS, Acute Taste/Smell was removed from the game
