> coffee get’s so much worse when cold This is a myth. Bad coffee tastes better when hot because your sense of taste is dulled - reducing bitterness. Also, at higher temperatures, aromatics and volatile compounds are more airborne, improving the smell of coffee. Good coffee is better enjoyed around 60-70C

I don’t understand, you say it’s a myth and then said it’s better when warm? Regardless, I would say it’s an objective fact that good coffee is ruined at room temperature. It still tastes fine , but no where near as good. What especially irks me is that they could have just heated the stuff in a microwave [1] to 50°C and have a much better test.

I meant it's better when cooled, not straight off the boil. Bad coffee tastes better when it's too hot to drink. Good coffee tastes better when it's cooled.

Trung Nguyen did that: https://www.vice.com/en/article/a-vietnamese-company-is-brin... Seemingly as early as 2010: https://en.wikipedia.org/wiki/Trung_Nguy%C3%AAn#Weasel_and_L...

Ok i NEED to check this out. Thanks for the articles! (Wtf basically kopi luwak was created through colonialism? An even more cursed product now wow

I don't get kopi luwak though.

I assume that such coffee is good because the civet cat has taste for good coffee cherries, not really because of the digestive enzymes or whatnot.

> Both espresso samples were served at 22 °C to ensure a fair like-for-like comparison […] > It is noted that espresso is normally consumed hot and has transient sensory attributes that are temperature- and time-dependent. Hence, serving espresso at 22 °C will alter its sensory characteristics. This is a weird test, coffee get’s so much worse when cold. So people can’t distinguish between two bad coffees.

If you want to scald your mouth I don't think you need coffee to do that.
