Why even do that?
Simply put, large amounts of CO2 are created during roasting. When the coffee’s very fresh, fleeing CO2 may interfere with even extraction.
The lighter you roast, the less CO2 is created overall. But! Lighter-roasted beans are at the same time denser, making the escape of CO2 harder. So from our experience, it may take a bit longer for very light roasted coffees to reach their flavor peak, even up to around 2 weeks in some cases.
The lower roast degree, the faster the flavor peak will come. Also, don’t worry about all this resting thing THAT much. If the green is of good quality and your roasting was flawless, the coffee will taste just good one day later. It’ll always probably need a couple of days in order to perform ideally and that’s it.
Estimate your preferred resting time based on your roast colors and regular quality control cuppings!
