Gamey
Etymology
From "game" in the hunting sense — wild animals pursued for food — itself from Old English "gamen" (sport, amusement). What began as a word for playful sport came to mean the quarry of that sport, and then the distinctive flavor of its flesh.
adjective · /GAY-mee/
Having the strong, slightly wild, earthy flavor of meat from hunted or aged animals.
What it names
The assertive taste of venison, duck, or well-hung game that sets it apart from mild farmed meat.
Example
The venison was pleasantly gamey, with a depth beef never quite reaches.
Related idea
A cousin of funky: both name strong, wild flavors that reward an adventurous palate, but gamey belongs to meat while funky belongs to fermented foods like aged cheese.
