You are purposely conflating the temperature at which coffee should be made (~185), with the temperature at which coffee should be served (~160). Yes, some folks suggest they are drinking 175 degree coffee. Those folks are wrong.
“Similarly, as of 2004, Starbucks sells coffee at 175–185 °F (79–85 °C), and the executive director of the Specialty Coffee Association of America reported that the standard serving temperature is 160–185 °F (71–85 °C).”
For fun, I went and brewed a cup of coffee on my Nespresso. Coffee coming out was 185 degrees. The finished cup was 170 (but that obviously depends a lot on the cup).
If this was brewing into a foam cup, it would have been served very close to 185. Regardless I’m currently drinking a cup of coffee quite close to the 175 number you seem to think is unrealistic. Yeah, it’s hot. It’s definitely not the hottest coffee I’ve ever had, though.
