On the flipside, I purchased a Begian beer called Martens Pils. I opened the six-pack and found out it was in plastic bottles, foreshadowing the lack of quality. I'll either sneak it over to my neighbor's dog or see if the neighborhood coyotes and foxes will drink it...
I always find myself going back to the Guinness, though I'll occasionally mix it up and get some Murphy's or Beamish. Irish beers are usually quite good, even the ones that aren't stouts. That being said, I'm particularly fond of Augustiner dunkel.
Like I've said before, I just don't trust beers unless they're in brown bottles. Every Heineken I've ever had has been skunky. I've had Stella once or twice, IIRC, but I don't remember it. That probably means I wasn't impressed.
Corona's not terribly expensive down here, but no, I don't drink it. The lime wedge is a gimmick, used as an excuse to keep the bottle clear. I prefer my beer to be unflavored. Personal preference more than anything, though if you drink Smirnoff or Mike's Hard, I will make fun of you.
