"Gamey" is a somewhat subjective winetasting term. It's most often associated with older bottle-aged red wine from Bordeaux, Burgundy, and the Rhone, and describes a wine that has overripe, earthy farmyard notes. To the British, however, it refers to the flavor closely associated with the game bird grouse, which, when left to hang by its feet, reaches perfection right before the point of deterioration (yes, some people find the aroma downright pleasant). Too much "gamey" in either sense is considered a wine fault.
