There are different types of coffee beans that are used to make various kinds of coffee roasts. Lightly roasted coffee is preferred by many coffee lovers as it retains the original flavors of the coffee bean. Coffee drinkers often invest in an espresso machine to enjoy their favorite brew. With different types of coffee roasting, there are options to explore and experiment with the perfect roast to suit individual preferences.
The coffee roasting process begins with beans being roasted to bring out their flavors. Brewing a medium coffee results in a strong coffee taste. The grind size also plays a role in the extraction process. A medium grind is suitable for medium roast coffee as it will extract faster, while a finer grind is recommended for a stronger flavor.
Indulging in the craft of roasting coffee beans is a true art form, where the mastery lies in capturing the rich flavors and enticing tastes that ignite our senses. Traditional method holds a deep appreciation for its history and cultural significance.
Types of Coffee Roasting
Coffee is more than just a drink – it’s an art form. As someone who has been a coffee roaster for over 15 years, I’ve learned that how you roast coffee beans can completely transform their flavor. There’s a lot more to it than just “light” or “dark” roast. Each roasting method creates unique tastes and aromas by altering the physical and chemical properties of the bean. In this article, I’ll break down the major methods so you can better appreciate this underrated craft.
There are four main ways coffee is roasted:
- Light Roast
- Medium Roast
- Dark Roast coffee
- Specialty Roasts
French press is a brewing method that brings out the full flavor profile of coffee beans. During the roasting process, when the beans reach the first crack, they release aromatic compounds that give the coffee a rich and distinct taste. Dark chocolate notes are often found in coffees roasted to this level. French press allows for a full immersion brew, which extracts more oils and flavors from the beans compared to other methods. Lighter roasts, such as those in the light city range, have a brighter and more acidic flavor profile that is favored by some coffee enthusiasts.
Light Roast
They are roasted for a shorter amount of time at lower temperatures – typically between 350-400°F. The beans will have a light brown color and will retain much of their original aroma and acidity.
Some popular light grill:
- Cinnamon Roast
- New England Roast
- Half City Roast
Characteristics of light grill coffee:
- Acidic, fruity flavor
- High caffeine-content
- Lighter body
Light grill highlight the distinctive flavors of certain coffee regions and types. For example, a light grill Colombian coffee will have more of the fruity, citrusy notes the region is known for.
| Roast Name | Total Roast Time | Color of Beans |
| Cinnamon | Just 1st crack | Very light brown |
| New England | Before 2nd crack | Light brown |
| Half City | Middle of 1st and 2nd crack | Light-medium brown |
Light grill are great for people who enjoy the nuances of coffee flavors and aromas. They aren’t as bitter as darker roasts.
When brewing coffee using a drip method, it is important to consider the grind size. A coarse grind is recommended as it allows the water to pass through the beans at a slower rate, extracting the desired flavor notes. Light grill coffee beans tend to have subtle and delicate flavors which can be overshadowed if the coffee becomes overly bitter. In contrast, beans roasted the longest have bold and robust flavors, which can be enjoyed by those who prefer a stronger cup of coffee. The flavor profile and notes of the beans can vary greatly depending on the roast level.
Medium Roast
Medium roasts are roasted longer than light grill, between 400-430°F. The beans are a medium brown color. This is the most common and popular roast level.
Some popular medium roasts:
- American Roast
- Breakfast Roast
- City Roast
Characteristics of medium roast coffee:
- Balanced flavor that is not too acidic or bitter
- Sweeter and fuller body compared to light roast coffee.
- Retains some original flavors of bean while having more roast flavor
| Roast Name | Total Roast Time | Color of Beans |
| American | Middle of 1st and 2nd crack | Light-medium brown with some oil sheen |
| Breakfast | Just before 2nd crack | Medium brown |
| City | Early 2nd crack | Medium-dark brown |
Medium roasts are versatile for all coffee brewing methods. The roast brings out coffee’s signature nutty, chocolaty notes while still preserving some of the origin bean’s character.
Medium-dark roast is a popular choice among coffee lovers as it balances the rich and intense flavors with a smooth and milder taste. It is known as the best coffee for those seeking a less bitter experience. When coffee beans are roasted, they go through different stages, with medium grill being a point where flavors are developed while still preserving the bean’s natural characteristics. This roast also extracts faster, making it a convenient choice for busy mornings. For those looking for a unique experience, white coffee offers a distinct flavor profile as it is lightly roasted, producing a lighter color and nuttier taste.
Dark Roast
This is roasted until oils appear on the bean surface, between 430-480°F. The beans will be dark brown with an sheen.
Some popular roasts:
- Italian Roast
- Espresso Roast
- French Roast
Characteristics of dark coffee:
- Full body with a smooth mouthfeel
- Very low acidity
- Burnt, bitter flavors
- Higher caffeine loss during roasting
| Roast Name | Total Roast | Color of Beans |
| Italian | Into 2nd crack until oily | Very dark brown, shiny with oil |
| Espresso | Middle of 2nd crack | Dark brown, oily |
| French | Just past 2nd crack | Very dark brown, thick oil |
The bold, bittersweet flavor of roasts pairs well with milk and sugar. They are ideal for espresso-based drinks. The extra roasting also helps reduce some of the acidity that can bother those with sensitive stomachs.
Specialty Roasts
In addition to the main roast types, there are also specialty roasts that apply unique roasting techniques. These create specific flavors and experiences.
Some examples of specialty roasts:
- Espresso Dolce Roast – Mild acidity espresso roast
- Vienna Roast – Brown coffee with hints of caramel
- Full City Roast – Rich, sweeter medium roast
- Turkish Roast – Intense roast ground ultra-fine
Roasters get creative with specialty roasts to make unique flavor experiences. Things like altered grill times, different heat levels, and special processing methods result in new dimensions of coffee taste.
For instance, a Spanish roast might use a technique involving higher initial heat to develop sweetness. Or an Italian roast could be taken just past 2nd crack to remove even more acidity.
Specialty roasts require skill and experience to execute well. But the results let coffee lovers enjoy novel flavors.

Frequently Asked Questions
What Roast Has The Most Caffeine?
Light roasts retain more caffeine from the raw coffee bean because the roasting process breaks down some of the caffeine over time. Dark roasts can lose up to 10% more caffeine compared to an equivalent light roast.
Is Dark Roast Stronger Than Light Roast?
No, dark roast is not stronger in terms of caffeine content. The flavor is stronger and bolder though. Light roast will actually have a bit more caffeine. The longer roasting reduces caffeine levels slightly.
Which Roast Is Least Acidic?
Dark roasts are the least acidic roasts. The longer roasting process essentially “burns off” a significant amount of acidic compounds in the beans. Light and medium roasts retain more acidity from the bean.
Is Light Or Dark Roast Smoother?
Dark roasts tend to be smoother and have less “bite” because the long roasting mellows out the flavor. Light roasts accentuate the natural acidity and fruitiness of the bean which can taste sharper. Medium roasts strike a balance between smooth and acidic.
Can You Roast Coffee At Home?
Yes, you can roast green coffee beans at home with either simple devices like a frying pan or popcorn popper, or dedicated home roasting machines. Home roasting takes practice but lets you customize roast levels. Commercially roasted coffee is still recommended for beginners.
