“190 degrees is far above any reasonable temp”
195-205 is the optimal temperature for brewing coffee.
Flavor & odor rapidly dissipate from coffee over time.
For best results, brew at 200 and serve immediately, by the time it’s at “drinkable” temp flavor loss is minimal.
Of course, don’t be stupid with it - it’s coffee, HOT coffee, and holding it ‘twixt your legs is obviously dangerous.
If you don’t know coffee (obvious you don’t), I don’t want you getting in the way of me getting a good cup.
I know coffee and seriously do brew it with a hand thermometer. But I wait and don’t serve black coffee above 140
