title_body: Is it necessary to sort beans after roasting?
upvoted_answer: It will affect the flavor. Whether that's particularly noticeable depends on the bean, the roast you're going for, and how much variance there is in the roast. Whether it matters to you is a personal decision. 
  
  In my experience, over-roasted beans are worth removing from a light roast (I tend to prefer city roast at darkest), even if they're not actually burnt - the flavor of even a few dark beans will tend to overwhelm the more delicate flavors of a lighter roast. 
  
  That said, I use a popcorn popper; there tends to be a lot of variation in the results. If you have a better roasting setup, you can probably avoid a lot of the hassle.
