title_body: Butter coffee taste and effects?
upvoted_answer: I do not know if this will be a good answer for you but here it goes.
  
  When I lived in France (small rural community), I used to put grass fed unsalted butter into my coffee all the time. I got the idea from reading articles about Tibetans putting yak butter into their black tea.
  
  Personally I enjoy it. It is an acquired taste because it is has a very rich and heavy flavor. Do not put milk or cream into your coffee as it will completely change your perspective on this great coffee idea. For myself, I prefer not to drink it just as it, safe the bottom of the barrel sort of speaking. I generally would dunk my rather dense bread (sometimes biscuits) into it at breakfast time and have enjoyed doing this as such for many years. 
  
  For myself I only do this in the mornings.
