Development Time - Time vs. Percentage

Posted by Patrik Rolf Karlsson on


This week, we've returned to the whiteboard to explain our views on measuring the duration of your roast after the first crack has begun. There are many variables to measure when roasting coffee, and time is a constant reference for all roasters.

There are however many ways the roasters approach to time, with some preferring to use percentages to measure or guide them. In this video, we explain our preference to measure the time after crack independently and give our opinion on 'development time'.
