Declining heat curve
Each batch follows an 11-minute profile with a short development phase after first crack.
Small-batch coffee roasted in split lots, rested seven days, and profiled for slow brewing.


Ember began with a simple refusal: to roast for colour alone. Our head roaster works from a declining heat curve, dropping batch temperature at the first sign of second crack, then resting beans for seven days. The result is a roast with a narrow band of development: dark enough to carry cocoa, light enough to keep the fruit. No smoke, no shine, no shortcut. Just time, fire, and a very quiet room.
