The Four Main Coffee Roasts: A Guide to Roasting Levels

In this article, we will explore the four types of coffee roasts; Light, Medium, Medium-Dark, and Dark, and how roasting transforms raw, green coffee beans into the aromatic and flavorful beans we grind and brew. The degree of roasting significantly influences the coffee’s flavor, acidity, body, and aroma. I have found that understanding these roast levels helps coffee enthusiasts select the right beans to match their flavor preferences and brewing methods. While there are numerous roast variations, they generally fall into these four key categories.

Four Types of Coffee Roasts:

1. Light Coffee Roasts

Light coffee roasts are roasted at lower temperatures, typically between 350-400°F (177-204°C). They are known for their high acidity, bright flavors, and ability to retain the original characteristics of the coffee beans.

Characteristics of Light Roasts:

• Roasted at lower temperatures, stopping just before or at the first crack.
• Retains more caffeine compared to darker roasts.
• Highlights the original flavors of the beans, preserving floral, fruity, and citrus notes.
• Lighter body with a crisp and clean taste.
• Higher acidity makes it ideal for those who enjoy bright and complex flavors.
• Minimal caramelization results in no burnt or smoky flavors.
  
  

Best Brewing Methods for Light Roasts:

• Pour-over (e.g., V60, Chemex) to highlight the intricate flavors.
• AeroPress for a balanced, crisp profile.
• Drip coffee makers for convenience while still preserving acidity and brightness.

Popular Light Roast Examples:

• Cinnamon Roast – Lightest roast level, with a grain-like taste and pronounced acidity.
• Half City Roast – Slightly darker than cinnamon roast but still maintains bright flavors and high acidity.

2. Medium Coffee Roasts

Medium coffee roasts are roasted at 410-430°F (210-221°C), reaching the first crack. These roasts strike a balance between acidity, body, and flavor, making them one of the most popular roast levels worldwide.

Characteristics of Medium Roasts:

• Roasted at a temperature that allows for some caramelization of sugars while preserving some original flavors.
• Well-rounded flavor with moderate acidity and a slightly heavier body than light roasts.
• Notes of chocolate, nuts, and mild fruitiness.
• Offers balanced sweetness with hints of caramelization.
• Less acidic than light roasts but still retains some brightness.

Best Brewing Methods for Medium Roasts:

• Drip coffee machines to bring out the balanced flavors.
• French press to enhance body and mouthfeel.
• Espresso machines for a smooth, well-rounded shot.

Popular Medium Roast Examples:

• City Roast – A well-balanced roast that highlights both the bean’s natural flavors and caramelization.
• Breakfast Roast – A smooth and mild coffee often preferred for morning brews.

3. Medium-Dark Coffee Roasts

Medium-dark roasts are roasted at 430-450°F (221-232°C), reaching the second crack or just before it. These roasts have a richer body with bold flavors, lower acidity, and a heavier mouthfeel.

Characteristics of Medium-Dark Roasts:

• Roasted at a higher temperature, allowing for more caramelization and oil development.
• Lower acidity compared to light and medium roasts.
• Rich, deep notes of chocolate, spice, and roasted nuts.
• Slightly oily surface begins to develop on the beans.
• Fuller body and stronger aroma than lighter roasts.
• It is ideal for those who enjoy a strong but not overly bitter coffee taste.

Best Brewing Methods for Medium-Dark Roasts:

• Espresso machines to enhance the rich, bold flavors.
• French press to extract deeper, complex flavors.
• Moka pot for a concentrated, full-bodied cup.

Popular Medium-Dark Roast Examples:

•  Full City Roast – A bold and flavorful roast with subtle smokiness.
•  Viennese Roast – A slightly darker roast with balanced bitterness and caramelization.

4. Dark Coffee Roasts

Dark coffee roasts are roasted at 450-480°F (232-249°C), well into the second crack. These roasts are known for their bold, smoky, and bittersweet flavors, often masking the original characteristics of the beans.

Characteristics of Dark Roasts:

• Roasted at the highest temperatures, resulting in a bold and intense flavor profile.
• Very low acidity with a heavy body and prominent smokiness.
• Strong roast, caramelized, and chocolate notes.
• Beans have a shiny, oily surface due to the release of oils.
• Bittersweet undertones, with some varieties having hints of caramel or burnt sugar.
• It is often used in espresso blends for its intense and syrupy qualities.

Best Brewing Methods for Dark Roasts:

• Espresso machines for a rich, full-bodied shot.
• Turkish coffee for a thick, intense brew.
• French press to capture the deep, bold flavors.

Popular Dark Roast Examples:

• French Roast – One of the darkest roasts, known for its bold and smoky profile.
• Italian Roast – A deep, strong roast often used for espresso blends.
• Espresso Roast – A dark roast specifically designed for espresso brewing, offering a rich and syrupy body.
