This is a page that describes how to add an off-flavor/off-aroma to a commercial beer.
Oxidation
Open a very cold beer and pour out ~ 20 mL (~ the neck of a std bottle)
Darker beers display a "cardboard" oxidation aroma
Hoppy beers loose the hop aroma
Lightstruck
Lightstruck, or "skunked" or "skunky", beer
Leave a clear bottle of beer (Rolling Rock) in the sunlight for 30 mins or expose to UV light source. Some beers use chemically modified hop extracts to prevent the formation of this off-aroma.
Any beer with hops can produce a skunky aroma (mercaptan) "3-methylbut-2-ene-1-thiol" (MBT)
