There are definitely speciality shops that sell dark roasts like you might want. One in the UK, Rave, sells the most amazing Italian-style blend with robusta mixed in. It's not fruity at all, just pure dark roasty flavour (yes, I've got an espresso bar lol.)

That darker style gets frowned upon a lot ("bleuch! it's bitter!"), as a lot of people in the space have kinda embraced the more fruit-forward lighter roast stuff (if you roast darker, you tend to obscure them.) I like that too (some stuff is kickass), I just categorize it separately from darker stuff.

I believe some people have started calling it goop, presumably as an anthesis to soup, which is very coarsely ground espresso typically using lighter roasts.

Not sure where you're based (US?), but there will be stuff out there. Try r/coffee or your local forum maybe? Once you find a really good one, you'll probably just stick with it :-)

I’m going to hate myself for saying this and sounding like such a coffee snob, but: if coffee tastes bad to you, there’s a decent chance you just haven’t had a good cup of coffee.

I only say this because I used to hate coffee too, only having had Starbucks or crappy supermarket coffee made at home. But then I had a cup of coffee at a very good restaurant and it was so delicious. It was just black coffee, good beans prepared right.

Turns out I just prefer light to medium roasts and found the right brewing times and temps that I like best. Every time I have Starbucks it still tastes awful.

There are actually a whole bunch of good medium to dark roasts out there, but third wave coffee is hip and has been for a while.

If you like Starbucks beans, you'd probably like a better dark roast. Try Lavazza. Coffee snobs will look down on it, but they're highly consistent like Starbucks while offering more variety and more flavor. Lavazza Super Crema makes a pretty nice espresso and is cheap relative to high-end coffees.
