Diedrich IR-5 Analysis roasted by Doris Garrido and written by Chris Kornman
Doris took this Wet Hulled coffee through the paces this week on our Diedrich IR-5 and is debuting here her new airflow profile for the first time as a Crown Jewel analysis.
Running into some recent struggles attempting to extend Maillard and spending a ton of time in the drying phase, she consulted Evan, who suggested she open the airflow a bit early on. In the Diedrich, so long as the burners are running above minimum, this has a two-pronged effect. First, it feeds a little extra oxygen to the flame, making it more efficient at heating the drum. Second, early in the roast, it aids the evacuation of moisture and steam from the drum as coffee begins to shed its water content.
Following the turning point, Doris closed the airflow briefly before color change, and reopened it again anticipating first crack. It’s a delicate dance of balancing burner power with airspeed through the drum, and in this instance navigated with precision and skill.
A nuanced roast with exceptional results, this coffee was on the light side at 51.68 ground ColorTrack but impressed us all with its complexity and balance and complete lack of underdeveloped notes. Myriad herbal notes accompanied dried-fruit sweetness with hints of cardamom and cinnamon.
Give this coffee a little bit of an early soak before hitting it with heat (not too much, or for too long), and let it develop gently for best results.
