title_body: Does craft beer have more nutritional values than regular beer?
upvoted_answer: So... I guess it depends on what you're deeming nutritional value. Beer has 4 main ingredients:  
  
  
  Water
  Grain
  Yeast
  Hops
  
  
  The biggest mineral difference is going to come from the water source of the brewery. Following the exact same formula recipe/mashing instructions/yeast used/fermentation conditions (temperature, altitude, fermentation vessel)/time/etcetera... you can get very different flavor beers if the water source is different. 
  
  The next varying source of minerals would probably be in yeast. Unfortunately, I can only find evidence of all brewing yeast lumped together at the moment. 
  
  The interesting part in craft brewing, especially at the homebrew-mad-science level, becomes all of the additives that can be placed into beer. I once met a brewer that dry-hopped smoked salmon bones (right they aren't hops but the same technique) in their secondary fermentation (or clarifying stage) chamber!
  
  These examples would be more "here is a random thing" that I found rather than being able to give you a definite answer as to "more nutrition" being provided than big-beer manufacturers.
