The 8 Stages of Specialty Coffee Roasting Explained

When you buy specialty coffee, the roast level isn’t just a color—it’s a carefully chosen stage that shapes everything from acidity to aroma. But with terms like ‘city roast’ and ‘full city’ floating around, it’s hard to know what you’re actually getting. If you’ve ever wondered why some coffees taste bright and juicy while others are bold and smoky, the answer starts with understanding these roast stages.

Specialty coffee roasting is generally divided into eight defined stages, each with distinct visual cues, internal bean temperatures, and flavor outcomes. These range from the very light (barely developed) to the very dark (nearing carbonization).

What Are the Eight Coffee Roast Stages?

Coffee roasters classify roast levels based on bean color, surface texture, roast temperature, and the timing relative to the first and second cracks during roasting. Each stage affects acidity, sweetness, body, and aroma differently. The eight standard stages are: Light Roast, Cinnamon Roast, Medium Roast, High Roast, City Roast, Full City Roast, French Roast, and Italian Roast.

Light to Medium Roasts: Bright Acidity and Origin Flavors

The first four roast stages are typically lighter and preserve more of the coffee’s inherent characteristics—especially those from its origin, variety, and processing method. These are favored for showcasing floral, fruity, and acidic profiles.

1. Light Roast (LIGHT)

This is the lightest possible roast. The beans reach an internal temperature of approximately 205°C (401°F), just after the first crack ends. The exterior is a very light cinnamon or pale brown color. Flavor and aroma development are minimal, resulting in a cup that is often thin, sour, and underdeveloped. This level is rarely consumed but may be used for green bean inspection or roast testing.

2. Cinnamon Roast (CINNAMON)

Also called Light-Medium or New England Roast, it occurs around 195–205°C (383–401°F), just before or at the start of first crack. The beans appear yellowish-brown or light tan. Most of the grassy or “green” smell fades, and some aroma emerges, though the cup remains high in acidity and light in body. Common in traditional American-style roasting.

3. Medium Roast (MEDIUM)

This stage happens roughly between 205–215°C (401–419°F). The roast finishes midway through or just after the first crack. The beans show a light to medium brown color. Acidity is still present but begins to balance with emerging bitterness. Flavor, aroma, and body are more rounded, making this a popular choice for blended coffees and everyday drinking.

4. High Roast (HIGH)

Occurring just beyond medium roast, at around 215–225°C (419–437°F), this stage is slightly darker and finishes just after the first crack ends. The beans develop a light tea-like brown color. Bitterness increases and begins to balance acidity. This roast is especially appreciated in Japan and parts of Central Europe. It’s well-suited to beans like Kenya or Blue Mountain, where some brightness can remain alongside developing roast character.

City to French Roast: Balance, Boldness, and Body

From City Roast onward, the focus shifts toward balancing or subduing origin flavors in favor of roast-driven sweetness, body, and caramelized notes. These levels are common for espresso blends and drip coffee.

5. City Roast (CITY)

This is considered the most balanced and “standard” roast level, occurring between 215–225°C (419–437°F), usually just before the start of the second crack. The beans are a medium to dark brown. At this stage, acidity and bitterness reach equilibrium. City Roast is widely used for Brazilian and Colombian beans and serves as the baseline for classic American or French-style filter coffee.

6. Full City Roast (FULL-CITY)

A small step darker than City, this stage occurs around 225–230°C (437–446°F), just before the onset of the second crack. The color deepens further, and bitterness becomes more pronounced than acidity. Full City Roast is especially popular in Central and South American styles, and it works exceptionally well for iced coffee preparations due to its bold profile.

Dark Roasts: Espresso and Beyond

The darkest roast stages emphasize roast flavors over origin traits. Oils migrate to the bean surface, body increases, and acidity nearly disappears. These are the roasts for espresso, Viennese coffee, and strong milk-based drinks.

7. French Roast (FRENCH)

Considered a dark or European-style roast, French Roast happens around 240°C (464°F) or higher. The beans reach the beginning or middle of the second crack. They appear dark brown to nearly black and are oily on the surface. Acidity is nearly gone, replaced by a smoky, bittersweet intensity. Popular in France and for drinks like café crème or Vienna coffee. Fat content rises to the surface, contributing to a distinctive aroma.

8. Italian Roast (ITALIAN)

The darkest standard roast level used in specialty coffee, Italian Roast begins at around 240°C (464°F) and can go beyond. It’s used primarily for espresso preparation. The beans are very dark brown to blackish, with a shiny, oily surface. The roast flavor dominates completely—acidity is absent, and the cup is intense, smoky, and often used for fast-preparation methods like espresso or milk drinks such as cappuccino.

Roast Temperature & Visual Guide

Roast level is also categorized by roast color and the bean’s physical state (like oil presence or cracking stage). Here’s a summary:

Why Roast Stage Matters

The roast stage determines how much of the coffee’s origin qualities—like fruitiness, florals, or tea-like brightness—you’ll taste versus how much roast-derived flavor (like chocolate, nuts, or smoke) comes through. Lighter roasts preserve acidity and delicate notes, while darker roasts boost body, sweetness, and boldness at the expense of origin character.
