Understanding Coffee Roast Levels: From Light to Spanish

Ever stared at a menu or coffee bag and wondered what 'City roast' or 'Viennese roast' really means? Or picked up a bag labeled 'dark roast' only to find it tastes more like charcoal than coffee? Whether you're choosing beans for espresso or pour-over, knowing how roast levels affect flavor, acidity, and body makes all the difference in your cup.

In specialty coffee, roast levels range from very light (like New England or Cinnamon) to extremely dark (like Spanish or Heavy). Each level changes the bean’s color, surface oils, and flavor profile—from bright and acidic to bold and smoky. These aren’t just random terms; they reflect real, measurable differences in how long and hot the beans were roasted.

Common Roast Level Names and Their Appearances

Roast names can vary by region, but many are still used today. Here’s what each classic roast level typically looks like:

• New England (New England): Light brown, dry surface. Very lightly roasted.
• American (American): Medium brown, dry surface. A step darker than New England.
• Viennese (Viennese): Medium-dark brown, with a few drops of coffee oils visible on the surface.
• French (French): Moderately dark brown, with a thin layer of coffee oils.
• Espresso: Dark brown, with either a thin or thick layer of oils depending on the roast.
• Italian (Italian): Nearly black, shiny surface, with heavy oil—most commercial roasters don’t go darker than this.
• Dark French / Spanish (Dark French or Spanish): Extremely dark brown, almost black, with excessive oiliness.

The Traditional American Roast Naming System

Since the 19th century, American roasters have used a longstanding naming convention for roast levels. Though less common today, you’ll still hear some of these terms:

• Cinnamon (Cinnamon): Very light brown.
• Light (Light): The lightest end of what many call a ‘light roast’.
• Medium (Medium): A balanced mid-level roast.
• Medium High (Medium High): Often the darkest a typical ‘medium’ roast goes.
• City High (City high): Slightly darker than a standard American roast.
• Full City (Full City): Darker still, sometimes showing a few oil spots.
• Dark (Dark): Deep brown, shiny in places, similar to Espresso or French roasts.
• Heavy (Heavy): Very dark brown, oily, close to Italian roast level.

Of these, Full City is the most commonly used term today. It sits darker than the mid-20th-century American norm and overlaps with what many now call Espresso or French roast.

How Roast Color Is Measured: Agtron and SCAA Standards

With so many names and no universal standard, how do you know what you’re really getting? The Specialty Coffee Association of America (SCAA) developed a numerical system using the Agtron scale to remove guesswork. This method measures the roast color objectively:

• Roasted coffee is ground, spread in a shallow tray, and scanned with instruments that analyze caramelization.
• The result is matched to one of eight color blocks—and given a number from #95 (lightest roast) to #25 (darkest roast).
• These numbers reflect the degree of roast, regardless of what it’s called locally.

This system helps roasters and buyers communicate precisely about roast depth, avoiding confusion between terms like ‘French’ in one country versus another.

Frequently Asked Questions

What is the lightest common coffee roast level?

The lightest widely recognized roast is New England or Cinnamon roast, both producing a very light brown bean with a dry surface. These roasts highlight origin flavors but remain lightly developed. The SCAA’s Agtron scale would rate these around #95, the lightest end of the index.

What does a Viennese roast look like?

A Viennese roast is medium-dark brown with a few visible oil droplets on the bean surface. It’s darker than a standard American or City roast but not yet fully dark. It’s often used to bridge the gap between lighter fruity notes and deeper caramelized flavors.

How can you tell how dark a roast really is?

Beyond visual inspection, the SCAA’s Agtron system measures roast color numerically. Beans are ground and scanned, then assigned a number from #95 (very light) to #25 (very dark). This removes subjectivity from terms like ‘dark roast’ or ‘espresso roast.’

Is French roast the same everywhere?

No. While French roast generally refers to a moderately dark brown bean with thin oils, the exact shade and oil level can vary by country or roaster. The SCAA Agtron scale or clear visual cues (like surface oil and color) help identify it more consistently.

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

As coffee roasts darken, internal beans fats migrate to the surface and become visible as oils. Light and medium roasts usually look dry because the roast hasn’t progressed enough for oils to emerge. Darker roasts like French, Espresso, or Italian develop glossy surfaces due to these oils.

What’s the difference between Espresso and French roast?

Espresso roast is typically dark brown with variable oil presence, often used for espresso brewing. French roast is also dark brown but tends to have a thinner oil layer and is slightly lighter than Italian roast. Both are dark, but French is usually a touch lighter and less oily.
