How Different Cities Around the World Roast Their Coffee

Ever wonder why your favorite café in Tokyo serves a different roast than your corner shop in New York? Or why some beans taste great dark and others fall apart? The truth is, coffee roast levels vary wildly across cities—and often depend as much on local taste as the beans themselves.

From Tokyo’s leaning toward medium-dark roasts to Vienna’s love of dark roasts, global cities favor specific roast profiles based on tradition, bean origin, and local palates. Dark roasts dominate in Italy and France, while New York offers diverse options. Some beans—like Ethiopian or Kona—lose their unique flavors when roasted too dark, while Mexican and Guatemalan beans can shine with more roast.

Global City Roast Preferences

Different cities around the world gravitate toward specific coffee roast levels, shaped by local traditions, tastes, and the beans available. In Tokyo, medium-dark roasts are popular, though darker roasts are gaining ground. Historically, Western cities—especially in Europe—have favored dark roasts. New York typically leans toward city roast (medium), but its diverse population means you’ll find everything from light to dark. Vienna strongly prefers dark roasts, while France and Italy are known for their signature French and Italian roast styles, respectively. In recent years, many Western roasters have adopted the intense Italian/Brazilian-style dark roast, though steam-driven coffee remains popular.

Why Roast Level Matters for Bean Origin

Not all coffee beans respond well to heavy roasting. Ethiopian beans, for example, are best enjoyed with lighter roasts to preserve their unique floral and fruity characteristics—a deep roast would erase their distinct qualities. Similarly, Puerto Rico’s Yauco Selecto and Hawaii’s Kona beans lose their classic profiles when roasted to black. On the other hand, some beans develop interesting flavors with darker roasts: Mexican beans can take on a pleasant sweetness, while Guatemala Antigua retains surprising acidity and fruitiness even when dark roasted. Sumatra beans, typically low in acidity, become overly sweet and mushy if roasted too dark. The general rule? The darker the roast, the more flavor is lost. Over-roasting dulls the bean’s inherent qualities.

How to Roast Coffee at Home

Home roasting is one of the trickiest parts of specialty coffee, but it’s also one of the most rewarding. Freshness is key to a great cup, and roasting your own ensures the beans are as fresh as possible.

The easiest method is oven roasting. Preheat your oven to 230°C (446°F), spread the beans in a single layer with space for air circulation, and roast for about 10 minutes. Watch for color changes and listen for the “first crack”—a popping sound that indicates the roast is progressing. Remove the beans just before they reach your desired roast level, then let them cool as residual heat finishes the job. Cool them in a heatproof bowl by a window or outside.

Alternatively, you can use a home coffee roaster or a traditional hot-air popcorn popper with two vertical rotating metal plates (available at secondhand stores). Use an oven thermometer to monitor temperature. Once roasted, transfer the beans to a heatproof bowl and place it near a window or outdoors to cool.

After roasting, the next step is grinding. Grind size depends on your brewing method: espresso requires a fine, powder-like grind (for very short extraction times), while methods like siphon or AeroPress need medium grind (around 1 minute brew time), and drip coffee or French press work best with coarse grinds (for longer extractions). A too-fine grind with long brew times leads to over-extraction (bitter, harsh cups), while a too-coarse grind with short brew times results in under-extraction (weak, sour cups).

Storage matters too. Pre-ground coffee should be kept in an airtight container in the fridge (if your climate is humid) and away from strong-smelling foods—coffee easily absorbs odors. Some people even reuse coffee grounds as fridge deodorizers.

Frequently Asked Questions

Which cities prefer dark roast coffee?

Cities like Vienna, as well as traditional markets in Italy and France, strongly prefer dark roast coffee. Vienna is especially known for its love of dark roasts, while in France and Italy, the so-called French and Italian roast styles dominate. These roasts are typically dark, bold, and low in acidity.

What roast level is common in New York?

New York generally favors a city roast, which is a medium roast level. However, due to its diverse population, you can find coffee shops in New York offering everything from light to dark roasts, making it one of the more varied coffee markets globally.

Can you ruin a coffee bean by roasting it too dark?

Yes. Over-roasting, or going to a very dark roast (like French or Italian roast), can destroy many of the unique flavor characteristics of certain beans—especially delicate ones like Ethiopian or Kona. These beans lose their origin qualities and become overly bitter or burnt-tasting with excessive roast.

What’s the best roast level for Ethiopian coffee?

Ethiopian coffee is best enjoyed with a light to medium roast. A dark roast can erase the bean’s unique floral, fruity, and wine-like notes, which are best preserved with a lighter roast that highlights its origin qualities.

How do I roast coffee beans at home?

You can roast coffee at home using an oven (preheated to 230°C), a hot-air popcorn popper, or a dedicated home coffee roaster. Spread the beans in a thin layer, roast while monitoring color and listening for the “first crack,” and remove just before reaching your desired roast level. Let them cool afterward. For best flavor, grind just before brewing.

Does grind size affect coffee flavor?

Yes. The grind size should match your brewing method. Espresso requires a fine grind for short extraction, siphon or AeroPress uses medium, and French press or drip coffee works best with coarse. Incorrect grind size leads to over- or under-extraction, resulting in bitter or weak coffee.
