title_body: Is there something special about Corona that makes it suitable for adding a slice of lime?
upvoted_answer: I would say it's the light body, low maltiness and low bitterness that make it amenable to citrus additions (and perhaps other additions.)
  
  The low flavor and bitterness means:
  
  
  if you choose to add something, you need only a little of it before you can taste/smell the addition
  there's less "interference" from the flavors of the beer so the addition tastes cleaner
  
  
  Contrast with adding citrus to a Czech Pils for example. You'd have to add much more juice - the bitterness and malt backbone of the beer would compete with the citrus additions.
