title_body: Is there more caffeine with an AeroPress?
upvoted_answer: Aeropress coffee (hearby called Aerpresso in this post) is more concentrated than regular drip coffee.  However, if you are using similar amounts of grounds as you would in a drip machine, you shouldn't notice any difference.  Caffeine is highly soluble in hot water and most any extraction method utilizing hot water will result in nearly full extraction of caffeine from grounds.
  
  Aerpresso ends up somewhere in caffeine concentration between espresso (very concentrated) and drip coffee (less concentrated).  However, the total amount of caffeine is dependent more on the amount of grounds used that the extraction method (with the above listed methods). 
  
  So the the final answer is no.  There isn't more caffeine, but the Aerpresso is more concentrated.
