I agree that coffee doesn’t seem to taste its best until it’s cool enough to drink without any scalding sensation whatsoever.
A semi related story that provides me with regular light amusement;
Whenever we are at a trendy third wave coffee shop with my Father-in-law he always asks for his coffee ‘extra hot please’. I watch the barista smile and nod do absolutely nothing to make it any hotter than anyone else’s.
Father-in-law sits down and says ‘mmm good coffee’.
