So I can taste differences, but they simply don't matter enough for me. My areopressed coffee with nice fresh locally roasted beans does taste different from a mcdonalds pot. Less harsh, less chemically flavored. But for me those differences don't really matter. They are close enough that I can enjoy both.

But I would say I know I'm also weird in that food temp really doesn't bother me all that much. I enjoy my coffee even as it goes from hot to cold.

A steak for me can be more easily messed up. But then I've not tried instant coffee so maybe I've just never tasted the bottom of the barrel for coffee.
