Introduction
Coffee roasting is a crucial process that transforms green coffee beans into the flavorful, aromatic coffee we enjoy. The types of coffee roasts significantly impact the flavor profile, aroma, and body of the coffee. The three primary roast levels are light, medium, and dark, each offering distinct characteristics. Understanding these types of coffee roasts helps coffee enthusiasts and professionals select the right roast to match their taste preferences.
Light Roast
Characteristics
- Flavor Profile: Light roasts are known for their bright, acidic flavors and complex aromas. They often retain more of the original characteristics of the coffee bean, showcasing fruity, floral, or herbal notes.
- Color and Appearance: Light roasts have a light brown color and a dry surface, as the beans are not roasted long enough for the oils to break through.
- Caffeine Content: Contrary to popular belief, light roast coffee can contain slightly more caffeine than darker roasts, as the longer roasting process can break down caffeine molecules.
- Common Terms: City and City+ roasts fall within this category, with City+ being slightly darker but still maintaining the light roast characteristics.
Light roasts are favored by those who enjoy a vibrant, nuanced cup that highlights the unique qualities of the coffee’s origin.
Ideal Brewing Methods
- Pour-over: Allows control over brewing time and temperature, accentuating the coffee’s brightness.
- Aeropress: Offers versatility in brewing, allowing for experimentation to bring out subtle flavors.
- Cold Brew: Smooth and less acidic, which can complement the delicate flavors of a light roast.

Medium Roast
Characteristics
- Flavor Profile: Medium roasts offer a balance of acidity, body, and flavor complexity. They have a more rounded profile with caramel, nutty, and chocolatey notes, often with a hint of sweetness.
- Color and Appearance: Medium roasts are medium brown in color and have a slightly oily surface.
- Caffeine Content: Medium roast coffee has a moderate caffeine content, slightly less than light roast but still retaining a significant amount.
- Common Terms: Full City is a common term for a medium roast, representing a roast level that has developed further than a City+ roast but has not yet reached the dark roast stage.
Medium roasts are popular for their balanced flavor profile and versatility, appealing to a wide range of coffee drinkers.

Dark Roast
Characteristics
- Flavor Profile: Dark roasts have bold, robust flavors with pronounced smoky, bittersweet, and toasty notes. The acidity is much lower, and the original characteristics of the coffee bean are often overshadowed by the roast flavors.
- Color and Appearance: Dark roasts are dark brown to almost black in color, with a shiny, oily surface due to the oils that emerge from the beans.
- Caffeine Content: Dark roast coffee has the least caffeine among the types of coffee roasts, as the longer roasting process breaks down more of the caffeine content.
