Understanding Coffee Roast Levels: Cinnamon, City, and French

Ever wonder why the same coffee bean can taste bright and fruity one day, but deep and smoky the next? The secret isn’t in the bean variety alone—it’s in how long and at what temperature it’s roasted. Roast level dramatically shapes aroma, acidity, sweetness, and bitterness. If you've ever sipped a sour cup or a burnt-tasting brew and wondered why, understanding roast stages is your first step to better coffee.

Coffee roasts are commonly divided into three main levels: cinnamon (light), city (medium), and french (dark). Each brings out different flavors—lighter roasts preserve acidity and origin character, while darker roasts boost bitterness, body, and Maillard reaction-driven complexity.

What Determines Coffee Roast Level?

Coffee roast level refers to how long and at what temperature green coffee beans are roasted. Roasting transforms the physical and chemical structure of the bean: moisture evaporates, sugars caramelize, acids degrade, and hundreds of aromatic compounds develop. The longer and hotter the roast, the darker the bean becomes and the more bitter and less acidic the resulting cup. Roasters choose roast levels based on bean origin, processing method, and intended flavor profile.

Light Roast: The Cinnamon Stage

The lightest commercial roast level is often called “cinnamon roast,” though this doesn’t mean the beans taste like cinnamon. It gets its name from the color of the bean, which resembles cinnamon bark. At this stage, roasting stops early—just after the first crack—and beans typically reach an internal temperature of around 205°C (401°F). These roasts preserve high acidity, delicate floral or fruity notes, and the bean’s origin characteristics. The body remains light, sweetness is subtle, and bitterness is minimal. This level is preferred by those seeking clarity and terroir-driven flavors.

Medium Roast: The City Stage

The city roast (also known as full city or medium roast) is the most common stage for specialty coffee. Roasting continues through or just after the first crack and stops before the start of the second crack. Internal bean temperatures range roughly between 215–225°C (419–437°F). This level balances acidity and body, highlights the bean’s inherent qualities while beginning to add some caramelized sweetness and roast character. Many single-origin pour-overs and manual brew methods shine at this roast level. It’s versatile, approachable, and widely used in specialty cafés.

Dark Roast: The French Stage

The French roast is a dark roast level where beans are roasted well into or through the second crack, reaching internal temperatures of around 235–245°C (455–473°F). At this stage, acidity is nearly eliminated, and bitterness becomes prominent. The roast flavor dominates: expect smoky, bold, and sometimes charred notes. Oils often migrate to the bean surface, contributing to a heavier body. French roast is typically used for espresso blends or when a strong, intense cup is desired. Dark roasts showcase the effects of extended Maillard reactions and carbonization, creating the classic 'roasty' profile many associate with traditional coffee.

How Roasters Choose the Right Roast Level

Experienced roasters assess multiple factors before deciding on a roast profile: bean species (Arabica vs Robusta), origin (altitude, climate), processing method (washed, natural, honey), and intended brewing style. For example, a high-altitude Ethiopian Yirgacheffe might be best at a lighter roast to highlight citrus and floral notes, whereas a Brazilian bean with nutty, chocolate traits may perform better at a medium or dark roast. The goal is always to match roast level to the bean’s inherent qualities to achieve balance and clarity—or intentional boldness.

Frequently Asked Questions

What is the difference between cinnamon, city, and french roast?

Cinnamon roast is very light, stopping just after the first crack, with high acidity and bright flavors. City roast is medium, going slightly past the first crack, balancing acidity and body. French roast is dark, roasted well into or beyond the second crack, resulting in low acidity, heavy bitterness, and strong roasted or smoky flavors.

Which roast level has the most acidity?

Light roasts, such as the cinnamon stage, retain the most acidity. As roast levels darken, acids degrade, resulting in progressively lower acidity and more pronounced bitterness.

Does roast level affect caffeine content?

Roast level has a negligible impact on actual caffeine content by weight. However, darker roasts weigh less per bean due to moisture loss, so by volume (e.g. scooped), lighter roasts may contain slightly more caffeine.

Why do some people prefer dark roasts?

Dark roasts have a bold, bitter, and smoky profile with a heavier body. Some drinkers prefer the intense, robust flavor and the perceived strength of dark-roasted coffee, especially in espresso or milk-based drinks.

Can you taste the origin in dark roasts?

It’s harder to discern origin characteristics in dark roasts because prolonged heat diminishes the unique floral, fruity, or herbal notes. The roast flavor tends to dominate, masking subtle terroir-driven attributes.

What’s the right roast for pour-over?

Most pour-over enthusiasts prefer medium roasts (like city roast) to highlight clarity, acidity, and nuanced flavors. Light roasts can also work well, offering brighter, more complex cups, while dark roasts often overwhelm the brewing method’s subtleties.
