The Complete Guide to Coffee Roast Levels

When you buy a bag of specialty coffee, have you ever wondered why some taste bright and juicy while others are bold and smoky? The answer lies in how the beans were roasted—not just how long, but exactly which stage of roasting they reached. Understanding roast levels helps you choose beans that match your flavor preferences and brewing style.

There are six main roast stages: light, medium, city, full city, Vienna, French, and Italian. Each begins and ends at a precise point in the roasting process—most notably around the first and second cracks—and brings out vastly different flavors in the cup.

What Are the Main Coffee Roast Stages?

Coffee roasting is divided into several key phases, each defined by the roast’s progress relative to the bean’s physical reactions—especially the first and second cracks. These stages range from very light (just before the first crack finishes) to very dark (well after the second crack ends). Each stage has a technical name, a common industry label, and produces a distinct set of flavors and visual traits.

Light Roast Stages

Light roasts are stopped just before or at the tail end of the first crack. They develop minimal roast character, preserving most of the bean’s origin qualities—but require precision to avoid underdevelopment.

Light Roast / Cinnamon Roast

This is the lightest commercial roast level, stopped just before the first crack completes. It’s rarely used today except for internal testing or in some mass-market canned coffees. At this stage, heat often doesn’t penetrate the bean core evenly, leading to uneven development—so many roasters opt for a double roast. The result is high acidity, grassy aromas, and a raw, underdeveloped profile. Visually, the beans are light cinnamon brown with blotchy, undeveloped surfaces.

Half City Roast (Light-Medium)

This stage occurs in the early part of the interval between the end of the first crack and the start of the second crack. Though similar to light roast, it allows for slightly more development. It’s seldom clearly distinguished from other light-medium roasts but is sometimes grouped with American-style or lightly developed Blue Mountain profiles. Acidity is bright but more balanced, and the cell structure remains firm, so oils don’t surface yet. The beans show moderate sheen and improved aroma over lighter roasts.

Common roast names: Light Roast, Cinnamon Roast, Half City Roast

Medium Roast Stages

Medium roasts occur during the first half of the time between the first and second cracks—or the early second crack. This is a balanced stage favored for classic American coffee styles and classic single origins like Colombian or Brazilian beans.

City Roast

This stage begins at the end of the first crack and continues into the early moments of the second crack. It’s widely regarded as optimal for highlighting origin character while adding some roast complexity. City roast preserves acidity while developing body and sweetness. Many roasters consider it ideal for showcasing beans like Colombian or Brazilian origins. Oils still haven’t surfaced, but the beans take on a slight gloss and more rounded flavor.

Full City Roast

This is the latter part of the first-to-second-crack window—right as the second crack begins or just after. It’s a favorite for those seeking a balance between acidity, sweetness, and roast tone. Full City brings out more body and a rounded finish while still retaining distinct varietal notes. It’s often used for Brazilian and other medium-bodied beans and is considered by some to represent the “perfect” roast for certain origins.

Common roast names: City Roast, Full City Roast

Dark Roast Stages

Dark roasts begin in the middle of the second crack and extend well beyond it. As roasting progresses, acidity fades, body deepens, and oils migrate to the bean surface. These stages are polarizing but valued for bold, intense cups.

Vienna Roast / French Roast

These two stages overlap and are sometimes treated as one. They cover the majority of the second crack. By now, the beans have begun releasing oils, and their color shifts toward a darker brown or approaching black. The roast flavors—like dark chocolate, caramelized sugar, and smokiness—start dominating, though some origin character may remain. The surface becomes shiny from emerging oils. Vienna and French roasts are popular for espresso blends and French press brewing, offering bold, rich cups with reduced acidity.

Italian Roast

This stage begins after the second crack has fully ended. It’s the darkest traditional roast level, where beans approach carbonization. The roast flavor completely overwhelms any origin characteristics—the coffee tastes primarily of bitter, ashy, and burnt tones. Italian roast is rarely used in specialty contexts but appears in some commercial or traditional espresso settings. The beans are very dark brown to black, oily, and brittle. Despite its name, this roast level is not commonly used by roasters in Italy itself.

Common roast names: Vienna Roast, French Roast, Italian Roast, Dark French Roast

Why Roast Stage Matters

The roast level determines much more than color—it shapes the balance of acidity, sweetness, body, and aroma. Light roasts preserve delicate floral and fruity notes but can taste sour or grassy if under-roasted. Medium roasts offer a balance suited for filter brewing. Dark roasts develop bold, smoky flavors but at the cost of origin complexity. Knowing these stages helps you select beans that fit your brewing method and taste preferences.

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 expand. It usually occurs around 385°F to 400°F (196°C to 204°C) and signals the beginning of light roast territory. Roasting past this point but before the second crack gives you light to medium 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 cellulose and the release of oils. It starts around 435°F to 445°F (224°C to 230°C) and marks the threshold into dark roasts. Roasting into or beyond the second crack leads to fuller body and bolder, more intense flavors, but less acidity and origin character.

Which roast level preserves the most origin flavor?

Light to light-medium roasts (like City or Half City) preserve the most origin characteristics, including floral, fruity, and acidic notes. These roast levels highlight the bean’s natural qualities with minimal roast influence, making them ideal for single-origin coffees.

What roast level is best for espresso?

Many espresso blends are roasted to Full City, Vienna, or French levels. These roasts develop enough body, sweetness, and crema potential while balancing acidity. However, some specialty espressos are brewed with lighter roasts to emphasize fruit and floral notes.

Why do some beans look oily and others dry?

Oily surfaces appear on beans roasted to medium-dark or darker (like French or Italian), as heat forces natural oils to migrate from inside the bean to the surface. Lighter roasts retain oils internally, so their surfaces stay dry and matte.

Is Italian roast actually used in Italy?

No—despite the name, Italian roast is not commonly used by roasters in Italy. The term refers to a very dark, nearly carbonized roast popularized elsewhere but not reflective of typical Italian roasting practices.
