For the home barista and coffee lover, this change is more than just visual: it’s evolving flavor profiles. This article is designed to provide information on how flavor elements change and combine during the roasting process. Ultimately, we aim to simplify your search for the perfect roast beans for your palate. Dive in and discover the art and science of coffee roasting.
| Roast Type | Acidity | Body | Flavor | Appearance | Caffeine |
|---|---|---|---|---|---|
| Light | More pronounced and intense | Clear and smooth | Retains inherent flavors | Light brown color, matte finish | Darker oils visible on the surface |
| Medium | Balanced | More robust and rich | Balance between bean flavor and roast | It may contain more caffeine if measured by volume | Balanced caffeine |
| Medium-Dark | Decreases | Increased density | Notes of caramel and chocolate | There is little difference in caffeine but it seems less due to bean expansion | Balanced caffeine |
| Dark | Practically absent | Intense | Bitter and robust notes | Dark and shiny with oils | There is little difference in caffeine, but it seems less due to bean expansion. |
How Does Roasting Affect the Flavor of Coffee?
Roasting plays a pivotal role in shaping the flavor landscape of your coffee. At its core, the taste that delights your palate hinges on the foundational flavor compounds inherent in the beans and the mastery with which a roaster harnesses them to craft a harmonious flavor experience. These fundamental compounds encompass sweetness, acidity, aroma, body (or mouthfeel), and bitterness. As the beans undergo varying levels of roasting, the intensity of these flavors oscillates, and their symphony with one another also transforms.
Brian Lokker of Coffee Crossroads astutely notes, “The age of the coffee, the processing method, the grind, and the preparation method also affect the flavor. But the type of roast offers a reference point, a general guide for the flavor you can expect.” Thus, while multiple factors influence the final taste, the roast type is a crucial compass, pointing towards the expected flavor nuances.
How Many Types of Coffee Roasting Are There?
Lokker (2013) states, “Because coffee beans vary, color is not a very accurate way to judge a coffee roast. But combined with the typical roasting temperature that produces a given brown color [and other additional factors], color is a practical way to categorize roast levels.” Coffee beans transition from green to yellow and various shades of brown during roasting.
When buying coffee, you might see labels like “French Roast Coffee,” Espresso Roast,” Full-City Roast,” or “Light Roast.” These terms refer to the roast level, but the coffee industry has no standard naming. This inconsistency means a medium roast for one company might be a dark roast for another.
The Coffee Roast Guide categorizes coffee into different groups.
- Light roast coffee
- Medium roast coffee
- Medium-dark roast coffee
- Dark roast coffee.
Light Roast Coffee
You’re not alone if you’ve ever wondered about light roast coffee. A common perception among many, including some of my friends, is its distinct acidity. Indeed, fair-roast coffees do boast a heightened and sharp acidity, leading to a bright and clean cup. Due to minimal caramelization during roasting, these beans retain much of their inherent flavors. This can be a boon for high-quality beans as the roasting doesn’t overshadow their natural taste nuances.
However, this characteristic can be a double-edged sword. While it enhances the flavors of premium beans, it can also amplify the shortcomings of lower-quality ones. Such coffees, when lightly roasted, might expose undesirable traits. Flaws in the roast can lead to bitterness and an unwelcome astringent mouthfeel. This roasting misstep can mask the potential of even top-tier coffee beans, denying us the pleasure of their complete flavor profile.

Medium Roast Coffee
Transitioning to a medium roast introduces a notable shift in the coffee experience. The aromas become more robust, and there’s a noticeable uptick in sweetness and acidity. Although acidity often reaches its zenith in medium-light roasts, medium roasts present a more harmonized flavor profile than their lighter counterparts.
One distinct characteristic of medium roast is the enhanced mouthfeel, providing a richer texture when sipped. Yet, the roast-related flavors haven’t fully set in, keeping the bean’s inherent tastes at the forefront.
Due to their flavor equilibrium, medium roast coffees are a favorite in specialty coffee cupping sessions. They serve as a benchmark, allowing experts to discern and rate the diverse flavor attributes and intensities.
Medium-Dark Roast Coffee
Delving into medium-dark roasting brings about distinct changes in coffee’s character. The coffee’s acidity diminishes with a more bottomless roast, and its aromatic complexity takes a backseat.
As the beans undergo further roasting, the flavors stemming from the roasting process become more pronounced, contributing to a denser body in the brew. Given that the beans undergo caramelization, a surge in bitterness is often observed.
As the coffee evolves in this roasting stage, the multifaceted flavors streamline, often leaning towards a more pronounced chocolatey undertone.
Dark Roast Coffee
Dark roast coffee often carries a mislabel — many mistakenly equate it to burnt coffee. But they’re distinctly different.
The coffee’s body intensifies in a well-executed dark roast, and the pronounced bitter notes from caramelization overshadow the bean’s inherent flavors. The once prominent acidity wanes dramatically, leaving behind mere hints of its original self.
Yet, within this bold profile, one can discern nuances often reminiscent of chocolate or cocoa beans. Undesirable flavors, such as those evoking smoke or ash, signal a roast gone awry and should not be mistaken for a genuine dark roast’s characteristics.
5 Points of coffee roasting that you need to know
- Flavor Transformation: As beans are roasted longer and turn darker, they gradually shed their original, inherent flavors. Instead, they absorb more taste characteristics from the roasting process itself. This means darker roasts often possess robust, smoky, or caramelized notes. Compared, lighter roasts retain more of the bean’s natural flavor profile.
- Body of the Coffee: The body or mouthfeel of the coffee goes through changes as it’s roasted. During the initial roasting stages leading up to the second crack, the coffee’s body intensifies, feeling richer and fuller. However, post the second crack, the body tends to lighten, offering a different texture in the mouth.
- Acidity Levels: Lighter roasts typically exhibit higher acidity levels, perceived as bright, tangy, sparkly, or crisp. On the other hand, the acidity diminishes as the roast gets darker, making the coffee feel smoother.
- Appearance of the Beans: One of the apparent visual distinctions between light and dark roast beans is their surface. Light roasted beans remain dry, showcasing their untouched, natural state. In contrast, darker roasts start to exude oils, giving them a shiny appearance.
- Caffeine Concentration: Contrary to popular belief, the caffeine content in coffee beans doesn’t vary drastically between light and dark roasts. However, due to the expansion of the beans during roasting, you may consume more caffeine with a light roast than with a dark one if you measure your coffee by volume. Conversely, if calculated by weight, the difference becomes negligible.
Conclusion
Understanding the nuances of coffee roasting can genuinely elevate your coffee experience. While the roast level, indicated by the bean’s shade of brown, offers a handy reference for its flavor profile, it’s merely a guideline, not an absolute. It provides a glimpse, a teaser of the flavors awaiting in your cup.
But there’s so much more than just color. The mastery with which a roaster guides the beans through the roasting process plays a pivotal role in sculpting the final taste. This artisanal touch imparts a unique signature to each batch.
Your flavor detection abilities, shaped by past sensory encounters, play a role too. We must remember that our palate, like any skill, can be honed and refined. We can heighten our tasting prowess by being mindful of the flavors dancing on our tongues daily. Immersing oneself in a spectrum of coffees from varied origins and roasts is a delightful way to train this sensory skill.
Now, a question for reflection: Which roast level resonates with your palate?
FAQs about Types of Coffee Roasting
What is the best coffee roast?
The “best” coffee roast is subjective and depends on individual preferences. Some prefer the bright and acidic notes of a light roast, while others lean towards the full-bodied richness of a dark roast. It’s essential to try various roasts and determine which flavor profile resonates with your palate. Remember, the best coffee is the one you enjoy the most.
How should coffee be roasted?
While roasting coffee in a pan or oven is cost-effective, it might yield less consistent results. For a more uniform roast and enhanced control over the process, specialized equipment like a popcorn maker or, even better, a home coffee roaster is recommended. These tools ensure even heat distribution, allowing the beans to roast uniformly. If you’re serious about your coffee and want to capture the essence of the beans, investing in dedicated roasting equipment will take your brewing experience to the next level.
Which coffee roast has the most caffeine?
It’s a common misconception that darker roasts pack more caffeine. In reality, the caffeine content in coffee beans doesn’t vary drastically between light and dark roasts. However, because darker roasts are denser, if you measure your coffee by volume (like with a scoop), you might get less caffeine with a dark roast than with a light one. On the other hand, if you measure by weight, the caffeine content remains relatively consistent across roast levels.
What is American roasting?
American roast refers to coffee beans roasted to a medium level, resulting in a moderate brown color. This roast is popular in the United States, hence the name. It showcases a balance between the inherent flavors of the beans and the characteristics introduced by the roasting process. Typically, an American roast retains some acidity and has less roast flavor than darker roasts, making it a favorite for those who prefer a balanced cup.
