title_body: Roughly how much caffeine am I ingesting when I eat chocolate coffee beans?
upvoted_answer: This seems to suggest that there is approximately 7mg of caffeine per coated bean.  I've no idea how much those weight per piece, or how many are in a bag, but the math should be fairly easy if you have access to such things.
  
  I found another manufacturer of a similar product which claims 40g for 28 pieces. Extrapolating that for your 150g bags gives roughly 700mg of caffeine, which sounds like way too much.  This could very greatly of course between manufacturers depending on chocolate thickness/weight.
