The Art of the Roast: How Time & Temperature Shape Flavor
Every coffee lover knows that magic moment when fresh roasted beans crack, release a rich aroma, and promise something special in the cup. But behind every great cup lies one essential truth: the roast makes the flavor.
At Sonofresco, we love helping home roasters and small cafés discover how small changes in time and temperature can completely transform their beans.
Light, Medium, or Dark – What’s the Difference?
Think of roasting like cooking—light roasts are your “rare,” dark roasts your “well done.”
-
- Light Roast: Brighter acidity and floral notes. Perfect for origins like Ethiopia Harrar or Costa Rica Tarrazu.
- Medium Roast: Balanced sweetness and aroma, a great all around choice for cafés.
- Dark Roast: Bold, smoky, and rich. Ideal for espresso blends or chocolatey Indonesian coffees.
Each bean has its own sweet spot. The key is experimenting until the flavor hits that “just right” moment.
