title_body: Are coffee tree berries edible?
upvoted_answer: TL;DR Yes, they are edible and non-toxic to humans.
  
  Coffee cherries, as they are properly called, are a thin papery skin and attached mucilage (what we think of as the flesh of the fruit). Coffee cherries are consumed as a drink, cascara, by coffee farmers in Latin America. 
  
  Coffee cherries contain more caffeine than coffee, on average, as they do not go though a roasting process. Depending on the green processing / pulping / milling process the coffee went through, coffee cherries often have a bitter and gamy flavor.
