Short answer: generally, yes. Long answer: The bitterness of coffee is determined by several things, but mostly the degree of the roast. Italians uses mostly robusta beans and loves them to be roasted to be almost pitch-black, near the point of burning, and mostly serves those in espressos which causes the strong bitter taste.
The character that is missing a tag here does not have an actual name in the game, so I'm not sure what to do here. Said character is the girl with the white hair flower. Fans call her the "dog girl" since it relates to something that happens to her in the game's story, but I'm unsure if that would be a good name for her tag.
