I see the value for American-style "espresso-flavored" drinks, or similar bottled/packaged products.
But, yuck, who on earth wants to drink actual espresso at room temperature?
The target of this process is not the residential use, but industry processing.
Instead of heating water to extract coffee and then latter cooling it to freeze dry and make instant coffee you keep the whole process at low temperatures, saving lots of power.
I do!
I think almost everything tastes better at room-ish temperature.
(Some things need to be colder or hotter to keep their texture, but I can't think of anything that _tastes_ better outside of the 16~25°C range)
Fine for iced drinks or Americanos. Even drinks with hot milk might be ok. I guess it's not so great at a neat shit of espresso.
Yeah not for me. I like my coffee hot. Scalding hot. McDonald's was great until they had that lawsuit.
In the style of Benjamin Buford "Bubba" Blue:
"You got your cold brew, your Japanese iced coffee, your iced americano. Then there's your mazagran, that's coffee with lemon juice, real refreshing. Your espresso tonic. Your iced latte, iced cappuccino, iced macchiato. You got your iced mocha, your frappuccino, your Greek frappé. Vietnamese iced coffee with the condensed milk dripping down real slow. Affogato, that's espresso poured right over ice cream. That's... that's about it."
