Traditional American Coffee Roast Level Names Explained

If you’ve ever wondered why your ‘French roast’ looks lighter than the last one, or whether ‘Vienna’ means the same thing everywhere—you’re not alone. Traditional American roast names like ‘Cinnamon’ or ‘Full City’ have been used for over a century, but their meanings vary by roaster and era. This guide sorts out the classic terms, their visual traits, and how modern tools like Agtron numbers bring clarity.

The traditional U.S. roast naming system includes 12 levels, from very light (Cinnamon, #95) to extremely dark (Heavy, akin to Italian roast). Key benchmarks like Full City (#45–55) and French roast (#25–35) have fixed visual cues—like oil sheen or dry surfaces—but exact matches depend on measurement.

Classic American Roast Names and Their Appearances

The traditional American roast classification follows a sequence dating back to the 19th century. The lightest is Cinnamon roast (#95), a very light brown. Light roast is the shallowest end of American-style roasts. Medium and Medium High follow, with Medium High being the typical endpoint for many American roasts. City High is slightly darker than standard American. Full City is deeper still, sometimes showing a few coffee oils on the bean surface. Dark roast is a deep brown with a shiny surface, similar to regional classifications of Espresso or French roast. Heavy roast is extremely dark and shiny, close to Italian roast. Deep French or Spanish roast is nearly black, with heavy oil.

Among these, Full City remains the most commonly used term today, often roasted darker than mid-20th century American standards. These names describe visual and surface traits but lack precise color consistency without tools.

European-Style Roast Names and Their Traits

Outside the American system, other traditional roast names include New England (# light brown, dry surface), American (medium brown, dry surface), Vienna (medium-dark brown, sparse oil droplets), French (moderate dark brown, thin oil layer), Espresso (dark brown, variable oil thickness), Italian (near-black, shiny, maximum depth for many roasters), Deep French/Spanish (extremely dark brown, extremely oily). Each name reflects a distinct roast level with observable surface and color differences, though exact shades vary by roaster.

These names are often used in European and specialty contexts, with French and Espresso being especially common for dark roasts. Italian and Deep French represent the darkest commercial roasts, with visible oil and near-black beans.

How SCAA’s Agtron System Standardizes Roast Color

To resolve confusion, the Specialty Coffee Association of America (SCAA) developed a numerical system based on Agtron measurements. This tool uses eight reference colors (numbered #95 to #25) matched to ground coffee samples. The process involves grinding the roasted beans finely, placing them on a special tray, and comparing them to calibrated color standards. The closest match determines the Agtron number, which correlates directly to roast depth.

The scale ranges from #95 (lightest, e.g., Cinnamon) to #25 (darkest, e.g., Heavy or Italian). For example, Full City typically falls around #45–55, while French roast aligns with #25–35. This numerical approach removes subjectivity, allowing roasters and consumers to match roast levels precisely.

Frequently Asked Questions

What is the difference between French roast and Espresso roast?

French roast is a moderate dark brown with a thin layer of coffee oils, while Espresso roast is dark brown with varying oil thickness depending on the roast level. Both are dark, but French tends to have a more consistent thin oil layer, whereas Espresso can range from light to heavy oil depending on the roaster’s approach.

What does Full City roast mean?

Full City is a classic American roast level that is darker than City but not yet dark roast. It often shows a few coffee oil droplets on the bean surface and typically corresponds to an Agtron number around #45–55. It’s a common benchmark for balanced dark roasts.

What is the Agtron scale and how is it used?

The Agtron scale is a numerical system for measuring roast color, ranging from #95 (lightest, like Cinnamon) to #25 (darkest, like Italian). Roasters measure ground coffee samples against standardized color charts, and the closest match determines the Agtron number, providing an objective way to classify roast depth.

Why do roast names like ‘Vienna’ vary between roasters?

Traditional roast names such as Vienna or French are based on visual traits (e.g., oil presence, color) but lack strict definitions. Different roasters interpret these names differently, leading to variations in actual roast depth. Modern tools like Agtron help standardize these descriptions.

Which traditional roast name is most commonly used today?

Full City is the most enduring traditional roast name, often roasted darker than in the mid-20th century. It remains a widely recognized benchmark for a dark but not overly oily roast, typically falling around Agtron #45–55.
