title_body: Of the various methods of decaffeinating coffee, which is the safest?
upvoted_answer: Swiss Water process is the best because it's the most natural and has the best percentage of decaffeination. However, none of the processes are dangerous, I repeat, none. Unless you consume the decaffeinating solvents somehow, that's a different case. -.-
