The 8 Professional Coffee Roast Levels Explained

When you buy coffee, have you ever wondered why some beans taste bright and acidic while others are deep and smoky? The answer isn’t just about origin or processing—it’s largely determined by how the coffee was roasted. Professional roasters use a set of standardized roast levels to shape flavor, body, and aroma. Knowing these levels helps you choose beans that match your taste preferences and brewing methods.

There are eight standard professional roast levels for coffee beans: from Light (also called Cinnamon) to Italian (near carbonization). Each level brings distinct changes in color, flavor, acidity, and bitterness.

What Are the 8 Professional Coffee Roast Levels?

Coffee roasters classify roast levels based on bean color, surface texture, temperature reached during roasting, and flavor development. These levels range from very light to nearly burnt, each affecting the final cup profile. Below are the eight standard roast categories used globally in specialty coffee.

1. Light Roast (Also Called Cinnamon Roast)

This is the lightest professional roast level. The beans are roasted to an internal temperature of around 196–205°C (385–400°F), just after the first crack. The exterior is a very light brown, almost cinnamon in color. At this stage, the roast is so light that most of the inherent flavors of the bean are underdeveloped. Acidity is present but flavors are thin, with grassy or grainy notes. Roasters typically use this level for green bean evaluation, not for drinking. Most coffee drinkers find it unpleasant on its own.

2. Cinnamon Roast (Commonly Known as Light Roast)

Also referred to as Light Roast, this level reaches slightly further into the roast than the bare minimum. Beans are taken to around 205–210°C (400–410°F), still just after the first crack. The color is a light tan to pale brown, resembling cinnamon. This is one of the most common roast levels for traditional American-style coffee. Acidity is high, sweetness is low, and the roast has a snappy, dry finish. Many light roasted beans intended for filter brewing fall into this range.

3. Medium Roast (Also Called Mild or City-Start Roast)

Medium roast occurs just after the first crack finishes and before the start of the second crack, typically at 210–220°C (410–428°F). The beans are a medium brown and have a balanced acidity with some emerging sweetness. Body is moderate, and you’ll start to perceive more complex flavors beyond just acidity. This roast level is widely used for both single-origin and blended coffees, especially in North America. It’s considered approachable, with a rounded flavor that highlights both origin character and roast influence.

4. High Roast (Sometimes Called City Roast or Medium-Dark)

High roast begins to approach the start of the second crack, at roughly 220–225°C (428–437°F). The bean surface shows a slight darkening, moving into a medium-dark brown. Acidity starts to mellow, while body and sweetness increase. This roast is commonly associated with Japanese and some European preferences. It offers a balanced cup with pronounced flavor, aroma, and a touch more bitterness than lighter roasts. It's often favored for its richer mouthfeel without diving too deep into dark roast territory.

5. City Roast (Standard Mid-Level Roast)

City roast is considered the most balanced and “standard” professional roast level. It occurs right at or just after the start of the second crack, around 225–230°C (437–446°F). The beans are a medium to medium-dark brown. At this stage, acidity and bitterness reach equilibrium. This roast is especially popular for Brazilian and Colombian beans and is widely used for drip coffee and filter brewing. It highlights origin characteristics while providing enough roast development for a satisfying cup.

6. Full City Roast (Approaching Dark Roast)

Full City roast takes place just before the middle of the second crack, at approximately 230–235°C (446–455°F). The beans are a darker brown with some oil beginning to show on the surface. Bitterness becomes more pronounced than acidity, making this roast popular for blends and espresso-style preparations. It’s especially suited for making various styles of iced coffee. This level is commonly used in Central and South American coffee profiles and offers a bold, well-rounded cup.

7. French Roast (Deep Roast)

French roast is a dark roast level that occurs in the middle to latter part of the second crack, around 235–240°C (455–464°F). The beans are very dark brown, nearly black in some cases, and oils are visible on the surface. Acidity is almost entirely muted, and the flavor profile is dominated by smokiness, bitterness, and roast-derived notes. This roast is extremely popular in Europe—especially France—and works well for milk-based drinks like café au lait and Viennese coffee. The body is heavy, and the roast character overshadows most origin traits.

8. Italian Roast (Very Dark, Near Carbonized)

Italian roast is the darkest professional roast level, achieved just before the beans begin to carbonize, at around 240–245°C (464–473°F). The beans are nearly black, oily, and have a shiny surface. The roast flavor is extremely intense, with virtually no acidity remaining. This level is mainly used for traditional espresso preparations, particularly in Latin countries. It’s ideal for fast extractions like espresso shots and is the base roast for many commercial espresso blends. The resulting cup is smoky, bitter, and heavy-bodied.

How Roast Level Affects Coffee Flavor

As coffee beans roast darker, several chemical and physical changes occur. The Maillard reaction and caramelization develop deeper flavors, while sugars break down and acids diminish. Lighter roasts preserve more of the bean’s intrinsic qualities like floral, fruity, or acidic notes. Darker roasts emphasize roasted, smoky, and bitter tones, often masking origin characteristics. The choice of roast level will dictate whether your coffee tastes bright and juicy or bold and chocolatey.

FAQ

What is the lightest professional coffee roast level?

The lightest professional roast level is Light Roast, also known as Cinnamon Roast. It is roasted just past the first crack to an internal temperature of around 196–205°C (385–400°F). The beans have a light cinnamon color, high acidity, and underdeveloped flavors, often used for bean evaluation rather than drinking.

Which roast level is most common in American coffee?

The most common roast level in American coffee is Medium Roast or Cinnamon Roast, typically roasted to 205–220°C (410–428°F). It balances acidity and body and is widely used for filter and drip coffee. City Roast is also popular for its balanced flavor.

What roast level is best for espresso?

Espresso can be made with a range of roast levels, but City Roast, Full City Roast, French Roast, and Italian Roast are most common. Italian Roast is especially traditional in espresso blends for its bold, smoky profile and heavy body.

Does roast level affect coffee acidity?

Yes. Lighter roasts retain higher acidity with brighter, tangier flavors. As roast levels deepen, acidity decreases and is replaced by bitterness and roasted flavors. Very dark roasts have almost no perceptible acidity.

Why do some roasts look oily and others don’t?

Oil on the bean surface becomes visible at darker roast levels, starting around Full City and becoming more pronounced in French and Italian roasts. Lighter roasts don’t produce surface oils because the beans haven’t been roasted long enough for internal oils to migrate outward.

Which roast level preserves the most origin flavor?

Light to Medium roasts preserve the most origin-specific flavors, including fruit, floral, and herbal notes. As roast levels increase, roast-derived flavors mask the inherent characteristics of the coffee bean’s origin.
