Sure. But doesn’t change the fact that for me, when you have good beans, black coffee is much nicer without any added milk or sugar.

When you use cheapo beans from Starbucks or the super market, it’s difficult to make good tasting black coffee. So making it with milk makes it drinkable.

Sure it does. But perhaps you underestimate the serious variety in coffee (and that folks still drink decaf). I've purchased a coffee advent calendar the last 3 years from a specialty coffee roaster here in Norway. 24 different coffees to try.

And let me tell you, they aren't all bitter. If I did a blind taste test, I'd swear some of these were teas. Some are more of the taste I'd expect from black coffee either here or the US, sure. But wow, is there variety.
