Coffee Roast Levels Explained
How roasting transforms green beans into your morning cup
What Happens During Roasting
Green coffee beans are dense, grassy-smelling, and taste nothing like coffee. Roasting triggers hundreds of chemical reactions — the Maillard reaction (browning, creating caramel and chocolate flavors), caramelization (sugar browning), and first/second crack (physical expansion as moisture and CO₂ escape). The roaster's job is to develop these reactions to the desired degree.
Light Roast
Roasted to just after first crack (385-400°F). The bean retains most of its origin character: fruit, floral, citrus, and tea-like notes. High acidity, light body, and a dry finish. Popular names: Cinnamon roast, Light City, Half City. Light roasts actually have slightly MORE caffeine than dark roasts (by weight).
Medium Roast
Roasted between first and second crack (410-430°F). The sweet spot where origin character meets roast development. Caramel, chocolate, and nut flavors emerge while retaining some brightness. Balanced acidity and body. Popular names: City roast, American roast, Breakfast roast.
Dark Roast
Roasted at or past second crack (440-470°F). The roast flavor dominates: smoky, bittersweet, ashy, and bold. Low acidity, heavy body, and oily surface. Origin character is mostly obscured. Popular names: Full City+, Vienna, French, Italian, Espresso. Very dark roasts (French/Italian) are increasingly uncommon in specialty coffee.
Which Roast Level is Best?
There is no "best" roast level — only what suits your taste and brewing method. If you want to taste the origin: light roast + pour-over. If you want a balanced, everyday cup: medium roast + drip or AeroPress. If you want bold, strong coffee: dark roast + French press or espresso. If you're new to specialty coffee, start with a medium roast and explore from there.
