This is worth savoring: Light roasts demand precision, and the devil is in the details of timing. If you’re chasing a filter roast with a short dry phase and Maillard, you’re already in a tightrope act—balancing speed and depth. The numbers you’re working with—4:15 dry, 3:15 Maillard, 1:25 development—hint at a race against time. But here’s the catch: your ROR (rate of rise) spikes during development, threatening to cut the window for complexity. The question isn’t just about how to slow the roast—it’s about how to let the beans breathe without losing their brightness.
The core issue lies in the interplay between heat application and bean response. A short dry phase means you’re not giving the beans enough time to absorb heat evenly, which can lead to uneven color and underdeveloped flavors. But if you push too hard into Maillard, you risk burning off the delicate acids that make light roasts sing. The trick is to let the beans do the work. Lowering power just before First Crack isn’t a compromise—it’s a strategic pause. This creates a gentle ROR drop, allowing the beans to expand and release volatile compounds without scorching. It’s about giving the roast a moment to exhale before the final push.
The real magic happens in the development phase. A long dev time isn’t just about time—it’s about heat distribution. If your ROR is too aggressive here, you’re roasting the surface instead of the core. The solution isn’t to speed up; it’s to let the beans dictate the pace. This means adjusting your machine’s output to match the beans’ natural rhythm. Some roasters use a “crash” in ROR by reducing power, which acts like a brake, letting the beans finish their Maillard reactions before the development phase takes over. It’s a delicate dance, but one that rewards patience.
Key points: Prioritize even heat distribution over speed. Adjust power before First Crack to control ROR, not just during development. Let the beans’ natural expansion guide the roast’s final stages.

Questions & Answers
What is a roast profile?
A roast profile is a set of temperature and time settings used in coffee roasting. It defines how coffee beans are heated and processed to develop flavor and aroma.
How do I create a roast profile?
To create a roast profile, set temperature and time parameters for each roast stage. Adjust based on bean type and desired outcome. Test and refine for consistency.
