This side-by-side compares how light, medium, and dark roasts differ across the qualities that matter most in the cup.
| Attribute | Light | Medium | Dark |
|---|---|---|---|
| Acidity | High | Medium | Low |
| Body | Light | Medium | Full |
| Origin flavor | Strong | Some | Faint |
| Roast flavor | Faint | Some | Strong |
| Surface oil | None | None | Oily |
A trade-off, not a ladder. Darker is not better, just different. You trade the bright origin notes of a light roast for the bold, roasty body of a dark one.
FAQ
Does roast level affect caffeine content? Only slightly, and less than most people expect. By weight, light roast beans are somewhat denser and can contain marginally more caffeine than dark roast; by scoop volume, the difference mostly evens out since dark roast beans are less dense. Bean origin also plays a role independent of roast: a naturally sweeter or more acidic bean will still show some of that character across a range of roast levels, just muted at the darker end.
