title_body: Additions to decaff coffee to complement taste
upvoted_answer: It is complicated. You may try adding cream, milk, salt (for masking up the aftertaste), but I don't recall any barista adding any other stuff for improving the decaf taste.
  
  You will hardly get it as good as a regular caffeinated coffee. The point is that the roasteries are often neglecting any improvements in their decaffeination process.
  
  For me, what worked out was checking any local roasteries which would actually perform the method called "Swiss Water Process" for decaf. This one is quite ok for a lot of people, and if your local roastery is committed to doing it right, then it is all good.
  
  Besides, have you tried any different brewing method?
