To play the devil's advocate, though, you wouldn't drink espresso at 80 degrees, no? Provided the cup is warm to begin with, you could brew at 50 degrees and still have perfect temperature espresso for drinking? Those 30 degrees are bound to save a bunch of energy, I'd think.

Although if the cup is warm to begin with, then you're using energy to warm up the cup which would eat into those energy savings.

The "optimal" drinking temperature of espresso is still considered higher than 50 degrees, like 60-65 degrees, though of course that is subjective, but the nice aspect of serving it hotter is that those that enjoy it hotter can have it and then it cools quickly and the customer can choose when to enjoy it or get to enjoy it at multiple temps.

It's relatively common around here for people (especially older folks) to order coffee extra hot. Holding the coffee for a while and smelling it as it cools to a drinkable temperature is all part of an enjoyable process.

I'm always wary of studies that claim that there is some optimal way to have coffee. People have different preferences.

I've gone one step further and is wary of any study that claims something highly subjective can be "optimized". "Best way to X" or whatever is always bullshit, just do what you feel like, aim to do whatever you find is fun and life will work out.
