(Of course, the actual process may be quite different, but that’s the traditional
urban legend story and I’m too lazy to look it up right now.)
Keystone Ice, brewed in fact by Coors, is 5.9% alcohol by volume—fairly strong if you’re used to drinking ~4.5% beers—and comes in a "specially lined can".
Smell: Really clean and neutral aroma; a bit of hard water, a bit of a soapy note that you get sometimes from the carbonation.
Taste: Corn, sweet enough so that it’s almost cloying; that’s the predominant flavor here and it’s hard to get past it. Otherwise, fairly non-descript.
Mouthfeel: A bit more body than a typical Macro. Fairly smooth, but leaves an odd coating/residue in the mouth.
Overall: More body seems more appealing than a typical Macro, but the excessively sweet corn is off-putting and screams "cheap".
