Understanding Coffee Roasting and Its Importance
Coffee roasting transforms green coffee beans into the aromatic, flavorful beans we use to brew coffee. During roasting, chemical changes occur, influencing the taste, aroma, body, and acidity of the final cup. Temperature plays a pivotal role in these transformations.
Why Is Temperature Critical in Coffee Roasting?
- Flavor Development: Different temperatures develop unique flavor notes.
- Roast Levels: Light, medium, and dark roasts correspond to specific temperature ranges.
- Consistency: Maintaining precise temperatures ensures uniformity across batches.
- Control: Accurate temperature readings help prevent over- or under-roasting.

Typical Coffee Roasting Temperature Ranges
Understanding the temperature ranges associated with each roast level is fundamental. Here’s an overview:
Green Coffee Beans
- Temperature: 20°C to 100°C (68°F to 212°F)
- Status: Beans are dry, green, and dense
Drying Phase
- Temperature Range: 100°C to 160°C (212°F to 320°F)
- Process: Evaporation of moisture, beans turn yellow
Maillard Reaction and First Crack
- Temperature Range: 160°C to 200°C (320°F to 392°F)
- Process: Caramelization, flavor development, first crack occurs around 196°C (385°F)
- Flavor Notes: Sweet, nutty, browned sugars
Development Phase
- Temperature Range: 200°C to 220°C (392°F to 428°F)
- Process: Color deepens, aroma intensifies
Second Crack and Dark Roasts
- Temperature Range: 224°C to 240°C (435°F to 464°F)
- Process: Second crack occurs around 224°C (435°F)
- Flavor Notes: Bitter, smoky, roasted flavors
