What's Your Favorite Coffee Roast?

Light roast? Dark roast? Somewhere in between? Here's a guide to coffee roasting, from light to dark.

The degree to which coffee beans are roasted is one of the most important factors shaping the taste of the finished cup. Before roasting, green coffee beans are soft, with a fresh, grassy smell and little or no taste. Roasting transforms those raw beans into the aromatic, flavorful, crisp beans we recognize.

Of course, other factors enter the equation too. Two coffees of the same variety from different origins, or grown in different environments, can taste quite different even when roasted identically (especially at light to medium levels). Age, processing method, grind, and brewing method all matter as well. But roast level provides the baseline — a rough guide to what to expect from the flavor.

Roast levels are most commonly described by the color of the roasted beans, from light to dark (or extra dark). As beans absorb heat during roasting, their color darkens, and oils appear on the surface at high temperatures. Because beans vary, color alone isn't a precise measure of a roast, but combined with the typical roasting temperatures that produce a given shade of brown, it's a convenient way to categorize roast levels.

Roast preference is subjective, and it can even be regional. In the United States, West Coast drinkers generally prefer darker roasts than those on the East Coast. Europeans also lean darker — hence the French, Italian, and Spanish roasts that occupy the deep end of the spectrum.

Roast names and descriptions are not standardized in the coffee industry. Starbucks, for example, uses the Starbucks Roast Spectrum™ to sort its coffee into three profiles: Starbucks® Blonde Roast ("light-bodied, mellow," like Veranda Blend™), Starbucks® Medium Roast ("smooth, balanced"), and Starbucks® Dark Roast ("fuller and bolder"). California roaster Rogers Family Company, by contrast, uses five levels from light to extra dark. (Its San Francisco Bay Fog Chaser Blend, for example, is a full city medium roast.)

Generally speaking, though, we can categorize the most common coffee roasts from light to dark as follows:

Light Roast

Light roast beans are light brown with a dry surface and no oil. They show a pronounced grainy acidity, and the bean's origin flavors are preserved to a much greater degree than in darker roasts. Light roasts also retain most of the beans' caffeine.

Light roast beans generally reach an internal temperature of 180°C to 205°C (356°F to 401°F). At or around 205°C, the beans pop or crack and expand in size — the "first crack" (for "second crack," see below). A light roast, then, generally means a coffee not roasted beyond first crack.

Common names for light roast beans include Light City, Half City, Cinnamon Roast (pulled just before first crack), and New England Roast (a favorite in the northeastern United States, roasted to the end of first crack).

Medium Roasts

Medium roast beans are brown and, like light roasts, show no oil on the surface.

They lack the grainy taste of light roasts and offer a more balanced flavor, aroma, and acidity. Caffeine content is somewhat reduced but still higher than in dark roasts.

Medium roasts reach an internal temperature between 210°C (410°F) and 220°C (428°F) — the end of first crack, just before second crack begins.

Common names at this level include Regular Roast, American Roast (the traditional roast of the eastern United States, taken to the end of first crack), City Roast (medium brown, the typical roast across the United States), and Breakfast Roast.

Medium-Dark Roasts

Medium-dark roast coffee is richer and darker in color, with some oil on the surface of the beans.

It has a heavier body than light or medium roasts.

The beans are taken to the beginning or middle of second crack — about 225°C (437°F) to 230°C (446°F). Roast-driven flavors and aromas become prominent, and the cup may carry a slightly spicy edge.

The most common medium-dark names are Full-City Roast (roasted to the beginning of second crack), After Dinner Roast, and Vienna Roast (roasted to the middle of second crack, sometimes classed as a dark roast).

Dark Roasts

Dark roast coffee is dark brown — chocolate-colored — and sometimes nearly black.

The beans have an oily sheen that usually shows up in the cup when brewed.

Roast-process flavors dominate over the coffee's origin character.

The cup is often bitter, even burnt, and the caffeine content is significantly reduced.

To reach a dark roast, beans are taken to an internal temperature of 240°C (464°F) — about the end of second crack — or beyond. They are rarely roasted above 250°C (482°F), where the body turns thin and the flavor is dominated by tar and charcoal.

Dark roasts go by many names, which can make buying one confusing.

Popular dark roast names include French Roast, Italian Roast, Espresso Roast, Continental Roast, New Orleans Roast, and Spanish Roast. Many dark roasts end up in espresso blends.

Summary

So there you have it — a quick guide to common coffee roasts from light to dark. Beyond the color scale, the key differences are:

• As roasts get darker, beans lose their origin flavors and take on more flavor from the roasting process itself.
• Body grows heavier up to second crack, then thins out again.
• Lighter roasts have more acidity than darker ones.
• Light roast beans are dry, while dark roasts develop surface oil.
• Caffeine content decreases as roasts get darker.

Finally, it all comes down to taste, flavor, and aroma. You might want a light roast in the morning (more caffeine) and a dark roast later in the day. Coffee — including the ideal roast level — is a matter of personal preference. What's yours?

FrontStreet Coffee Recommendation

During roasting, three elements determine a coffee's final flavor and must be kept in balance: sourness, sweetness, and bitterness. The darker the roast, the more bitter and full-bodied the cup; the lighter, the more acidic and delicate. If you crave balance, medium roast is the sweet spot. The FrontStreet Coffee Fazenda Rainha (Queen Estate) Brazil, a Yellow Bourbon from the world's largest coffee-producing country, is gently sweet and smooth; medium roasted, it reveals cream, peanut, chocolate, toasted bread, and sugarcane, and works equally well as pour-over, moka pot, or espresso.

For a sweeter medium roast, try the FrontStreet Coffee Strawberry Candy Gesha Blend, which pairs a honey-processed Costa Rican coffee with washed Panama Gesha and, at medium roast, shows both orange-blossom sweetness and rounded sugar — lovely as cold brew, pour-over, or espresso. The FrontStreet Coffee 2013 Natural Typica, a benchmark Yunnan specialty, delivers the balanced, gentle character of classic Yunnan arabica with hazelnut, brown sugar, black tea, and dried apricot notes. And the FrontStreet Coffee Jamaica Blue Mountain No. 1 — Typica grown in Jamaica's Blue Mountains, medium roasted so its acidity, bitterness, sweetness, and body fuse perfectly — opens with chocolate, roasted nuts, cream, and caramel in a way no other coffee quite matches.
