Master the key stages of coffee roasting: when to start dehydration, how fast to ramp, managing smoke, and using the drying slide.

Whether you're new to coffee roasting or looking to refine your technique, questions like "When does dehydration happen?" or "What’s the ideal ramp speed?" come up fast. These are not just technical jargon—they determine how your roast develops flavor, aroma, and body. Let’s break down the essential phases every roaster needs to understand: dehydration, ramp (or climb), smoke, and the often-misunderstood slide (or ‘drying’).
