You know how most cans of beer have that last sip that's really bad-tasting? Miller High Life is if the whole beer tasted like that.

It tastes like carbonated cheerios with some light metallic notes. It's not awful compared to something like Budweisser that comes pre-skunked for some reason, but like any pilsner it can never rise above the upper limit of "well, there are in fact worse pilsners."
