Roasting Kenyan Coffee - Profiling Kamwangi AA - Part 2 | Coffee with April

This week, we're presenting the second part of our latest series, sharing our process in profiling our first Kenyan coffee release of the season.

In the first video, we showed you our roast approach for this coffee, featuring two very different philosophies. Our initial roast included a 'soak' during the drying phase of the roast, increasing the overall duration of the roast. Our second profile featured a consistent burner position from charge to the first crack, leading to a total roast time almost 1 minute shorter than our initial profile. Once we had reached the first crack, we kept the length and end temperature the same (within 0.1°C).

In this weeks video, we take these batches and measure the changes following the roasting process. This includes measuring the moisture content and density of the green coffee and evaluating the colour of the roasted coffee. Most importantly, a full sensory evaluation should be undertaken as we find that this is the most important tool you can utilise when deciding how to profile coffee.

For those interested in the data, you can find information for both roasts below:

#1 - With Soak:
- 11:01 Total
