Diedrich IR-5 Analysis by Doris Garrido
This is the first Burundi Coffee I got to roast this year, a bourbon variety on a Natural processed coffee. This successful first roast presents an exceptionally clean cup brimming with apricot notes from the start, complemented by hints of dry cranberry and pineapple. It is enhanced by the sweetness of golden raisins, candy, and a smooth red apple flavor. This naturally processed coffee is well-executed, highlighting fruitiness without any harshness or overly fermented notes, and concludes with a subtle chocolate taste.
The roasting process I took was slightly fast, starting with a temperature of 442.6°F and maintaining full gas. This approach was intended to manage the bean's density, accentuate the acidity, and later in the roast regulate caramelization to achieve a harmonious sweetness. To achieve this, before the color change, I reduced the gas to 60% after 3 minutes and then to 30% right after. This adjustment allowed the roast to ride slowly but steadily through Maillard and reach the first crack. After cracking I turned off the burner as there was ample energy to complete the development simply fine.
For the air applications, I initiated airflow at the midpoint during color change, 50%, and increased it to 100% post the first crack. This controlled the rate of change and cleared any smoke during the development phase.
The roast lasted a total of 8 minutes and 7 seconds, with 4 minutes and 1 second dedicated to drying, 2 minutes and 37 seconds to the yellowing phase, and the final 1 minute and 29 seconds to development, ending at a drop temperature of 394.2°F.
The tasting yielded excellent results: a remarkably clean cup with a complex array of fruity flavors, all beautifully balanced with a refined sweetness. It is a delightfully delicate natural from Burundi that is sure to be enjoyed.
