Coffee Roast Levels
Coffee roast levels are the one variable the roaster fully controls, and they decide how much origin flavor survives versus how much roast flavor takes over. Roast is measured by how far the bean goes through two audible milestones: first crack, around 390 to 410F, and second crack, around 437 to 446F. Where the roaster stops sets everything from acidity to body to color.
This hub covers the levels we track: light, light-medium, medium, medium-dark, and dark. Each page explains what the roast does to flavor, which origins and brew methods suit it, and which reviewed beans land there.
The trade-off is simple. Light roasts stop near first crack and protect the bean's origin character: bright acidity, fruit, and floral notes. Dark roasts push into second crack and trade that origin clarity for body, bittersweet chocolate, and smoke. Medium sits in between and is the most forgiving daily range. Roast level barely changes caffeine, despite the myth. Pick the level that matches the flavor you want, not the strength you think it carries.

Guides & explainers
Common questions
What are the different coffee roast levels?
From lightest to darkest: light, light-medium, medium, medium-dark, and dark. Roasters track them by two cracking sounds. Light roasts stop near first crack, around 400F, keeping bright origin flavor. Dark roasts run into second crack, past 440F, trading that for body, bittersweet depth, and smoke. Medium sits between them.
Does dark roast have more caffeine than light roast?
No, that is a myth. Caffeine is stable during roasting and barely changes. Measured by weight, light and dark are nearly identical, with light holding a hair more. Measured by scoop, light roast wins slightly because the denser beans pack more per spoon. Dark tastes stronger; it is not.
Which roast level is best for espresso?
Medium-dark and dark are the traditional espresso choices. They give the low acidity, heavy body, and thick crema that pressure brewing rewards, and they are forgiving to dial in. Light-roast espresso is possible and increasingly popular, but it turns sour and finicky without precise grinding and temperature control.
