Understanding Coffee Roast Levels for Specialty Beans

When you buy specialty coffee, the roast level isn’t just a color—it’s a roadmap to flavor. But with terms like ‘city roast,’ ‘cinnamon roast,’ and ‘French roast’ floating around, it’s easy to get lost. Why does one coffee taste bright and juicy while another is smoky and bitter? The answer lies in how long and how hot the beans were roasted.

Specialty coffee typically uses light to medium-dark roasts, with light roasts ending just before the first crack finishes, and dark roasts going all the way through the second crack. Most experts agree: anything beyond full-city or French risks losing the bean’s unique origin character.

What Are the Main Coffee Roast Stages?

Coffee roasting is divided into broad levels—light, medium, and dark—each with several sub-stages defined by when they occur during the roast. These stages are measured by key acoustic events known as ‘first crack’ and ‘second crack,’ which signal physical and chemical changes inside the bean.

Light Roast Stage

The light roast stage includes roasts stopped just before or at the end of the first crack. This is where minimal heat has penetrated the bean core, often requiring a second pass to fully develop. These roasts preserve the most origin characteristics but can taste grassy or underdeveloped if not executed carefully.

Common Names:

• Light Roast
• Cinnamon Roast (also called Half-City)

Flavor & Appearance:

• High acidity, green/herbal aroma
• Surface may show speckles, color resembles cinnamon

Medium Roast Stage

This stage covers the first half of the interval between the end of first crack and the start of second crack, as well as part of the early second crack. It’s widely used for classic American-style coffee and respected single origins like Colombian or Brazilian beans. Beans are more developed, with balanced acidity and beginning oil development.

Common Names:

• Medium Roast
• City Roast
• Full-City Roast

Flavor & Appearance:

• More balanced acidity, developing sweetness
• Shiny surface, fuller body than light roast

Dark Roast Stage

Dark roasts begin midway through the second crack and continue to the end of it, or beyond. By this point, the beans are dark brown to black, oily, and carbonized. Most origin flavors are replaced by roast-driven bitterness and smokiness. Italian roast—roasting past the end of the second crack—is considered over-roasted in specialty contexts.

Common Names:

• Viennese Roast (mid-second crack)
• French Roast (late second crack)
• Italian Roast (post-second crack)

Flavor & Appearance:

• Dominant bitterness, muted acidity
• Shiny, oily surface, dark brown to black color

Why Do Some Roast Levels Rarely Appear in Specialty Coffee?

Light roasts like Cinnamon are seldom used outside of quality testing because they often fail to fully develop the bean’s inner structure, leading to uneven extraction. Dark roasts, especially Italian roast, are criticized for pushing beans to carbonization, erasing origin flavors and leaving only generic roast bitterness. In specialty coffee, the goal is balance—not extremes.

How Roast Level Affects Coffee Flavor

As roast intensity increases, sugars caramelize, acids degrade, and Maillard reactions intensify. Light roasts highlight floral, fruity, and acidic notes. Medium roasts offer balanced sweetness and body. Dark roasts emphasize bold, bitter, and smoky profiles. The roast level essentially determines which flavors survive the process—and which don’t.

Frequently Asked Questions

What is the first crack in coffee roasting?

The first crack is the initial audible popping sound beans make as internal moisture turns to steam and expands, causing the bean structure to fracture. It usually occurs around 385°F–400°F (196°C–204°C) and signals the start of light roast territory. Roasting stopped just before or at the end of this crack is typical for light or cinnamon roasts.

What is the second crack in coffee roasting?

The second crack is a softer, more rapid series of sounds caused by the breakdown of cellular oils and further structural collapse inside the bean. It begins around 435°F–445°F (224°C–229°C) and marks the threshold into dark roasts. City to Full-City roasts happen before it; Viennese, French, and Italian roasts occur during or after.

Which roast level preserves the most origin flavor?

Light to medium-light roasts (up to the end of the first crack or early city roast) preserve the most origin-specific flavors, including floral, fruity, and acidic notes. As roast levels deepen, those characteristics are increasingly masked by roast-derived flavors.

Is Italian roast used in specialty coffee?

No. In specialty coffee circles, Italian roast—which means roasting well past the second crack until the beans are black and oily—is considered over-roasted and is generally avoided. It produces a bitter, carbonized cup with little to no origin character.

What roast level is best for pour-over?

Most pour-over enthusiasts prefer light to medium roasts (up to full-city). These levels highlight clarity, acidity, and nuanced flavors that shine through with manual brewing methods. Dark roasts can overpower pour-over’s subtle extraction dynamics.
