Coffee Roasting
Roasting transforms green coffee into the aromatic beans we brew. Applying heat drives off moisture, triggers chemical reactions, and develops hundreds of flavor compounds. This category explains roast levels, roast stages, and how development time shapes flavor, body, and acidity.
Roast Levels
Light roasts, stopped soon after first crack, preserve acidity and origin character. Medium roasts develop sweetness and body. Dark roasts emphasize bittersweet, roasted notes and reduce acidity.
No roast is universally best; the goal is matching roast level to the bean and the intended brew method.
Stages of a Roast
A roast moves through drying, the Maillard reaction and caramelization, and development. First crack marks the transition to light roast territory.
Development time after first crack is a key variable. Too little tastes underdeveloped; too much bakes the coffee flat.

Frequently Asked Questions
What is first crack in coffee roasting?
First crack is the audible pop when steam pressure builds inside the bean and causes it to expand, marking the start of light roast territory.
Which roast has the most caffeine?
Light roasts retain slightly more caffeine per scoop, but the difference is small. By weight, light and dark are nearly equal.
Is dark roast stronger than light roast?
Dark roast tastes bolder and more bitter but is not stronger in caffeine. Light roast often has more acidity and origin character.
How long should development time be?
Development time after first crack typically runs 20 to 30 percent of total roast time. Too little tastes underdeveloped; too much bakes the coffee flat.
