How hot is a cup of black coffee?

There's no single answer to how hot a cup of black coffee is, as it depends on several factors:

* Brewing method: Different methods produce coffee at varying temperatures. French press coffee tends to be hotter than drip coffee.

* Personal preference: Some people prefer their coffee piping hot, while others like it lukewarm.

* Time since brewing: Coffee cools down over time.

* Environment: A hot cup of coffee will cool down faster in a cold room.

However, here are some general guidelines:

* Brewing temperature: Most coffee makers brew at around 195-205°F (90-96°C).

* Ideal drinking temperature: Many coffee experts recommend drinking coffee between 150-170°F (65-77°C). This is hot enough to enjoy the flavor but not too hot to burn your mouth.

Important Note: It's always best to let your coffee cool down a bit before drinking to avoid burns.
