Beer Myths

I was particularly interested in the following myths:

• The darker the beer, the more alcohol it contains.
• This one seems quite odd, as I can think of no reason people would believe this. All of the higher alcohol content beers I have had were lighter beers, but I just don't see what color would have to do with alcohol content.

• Beer is ruined if warmed and then refrigerated.
• This one I believed, but it is at least somewhat true so I can't really buy it being a true myth. Some quality reductions happen over time from this practice, but nothing too harmful.
  

• The Guinness they sell in Ireland is better.
• I fully believe that drinking locally accurate beer improves the experience. When I am in Mexico, I want a Mexican beer even if it is not the best beer. I understand that the beer in Ireland is the same as the beer sold here in the States, but locale does have some impact.

• Beer shouldn't be bitter.
• It can be harder to learn to love an IPA vs. an Oatmeal Stout, but the journey is well worth it. A good high IBU ale can be very tasty, and I will be brewing one before the end of summer, but bittering is a necessary step in brewing any beer.
  

• Corona is Mexican piss, and Singha has formaldehyde in it.
  
• WTF? It sounds like drunk talk to me.
