On a sweltering hot day, especially after a hard day of manual work, a frosted glass of ice cold Coors or Bud is actually refreshing.
But yeah, in general, the list of American beers and light beers in this thread is spot on.
Bud, Coors, Miller, PBR, MilBest, NatLite, Strohs, any Ice or lite beers, etc. all taste not so good really. They are just simply not very good tasting, nor good at getting you drunk. They're just good at filling your gut with beer for repeated trips to splash your boots. I know guys that would drink 10 in a sitting and be barely drunk, but out 50 bucks.
For a good tasting beer, IMO a domestic micro-brew IPA or Amber has a really great taste. One or two on a hot summer night is an excellent way to unwind.
But I've mostly given up drinking. Those days are hopefully in my rearview mirror for the most part.
