Light, Medium, and Dark Roast:
What the Difference Actually Means
Roast level is a trade-off — not a preference hierarchy.
Four Levels
Roast level is one decision made by the roaster that affects everything that follows — acidity, body, sweetness, origin character, and which brew methods work best. It is not a scale of quality. It is a trade-off: as roast increases, origin flavors give way to roast flavors, acidity drops, and body shifts. Understanding where those trade-offs happen is how you choose the right coffee for your cup.
The bean color gradient above each column is illustrative — green beans move through cinnamon, to light brown, to dark chocolate, to near-black as roast develops. The oils you can see on a dark-roasted bean's surface are sucrose caramelisation products pushed out by the heat.
Inside the Drum
The Physics of Roasting — First Crack to Second Crack
Roast level is defined by where in the roasting process the roaster stops the heat. Two physical events — first crack and second crack — are the primary markers the roaster uses to navigate.

What Each Roast Level Delivers
Bright, fruit-forward, tea-like body. Origin flavors at full expression. Floral and fruity notes preserved. Best for single origins with complex terroir — pour over and filter methods.

The Trade-Off
Acidity and Body Across the Roast Curve
The relationship between roast level, acidity, and body follows a predictable curve — with one important exception at the dark end.
Relative Intensity Across Roast Levels
Note the body curve: it rises steadily from Med-Light through Med-Dark, then drops slightly at Dark. Very dark roasts break down the bean's cellular structure to the point where body becomes thinner again — bold and intense, but not the heaviest mouthfeel. French press brewing restores some of that body regardless of roast level.

Where Our Products Sit on the Roast Scale
Every Simple Coffee bag carries a dot scale — one to four filled circles — that maps directly to the four roast levels above. Here is the full product map.

Most Simple Coffee products sit at Med-Dark — the balance point where Northern Thailand Arabica's natural sweetness and body are fully developed without losing the origin character that direct trade sourcing is meant to preserve.
