Exploring Drum Roasting: A Guide by Daniel Horbat, Founder of Sumo Coffee Roasters

Drum roasting is a classic method of roasting coffee beans that has been used for many years in the coffee industry. In this blog post, we will explore how drum roasting works and why it is still a popular choice among roasters.

Daniel Horbat, the founder and roaster of Sumo Coffee Roasters, is an expert in drum roasting. He uses a Probat P12 III Series drum roaster to create delicious coffee beans. Daniel explains that drum roasters use conductive heat from the drum and surrounding hot air to roast the beans, while hot-air roasters rely solely on convection heat.

One of the key advantages of drum roasting is the control it offers over the roasting process. Roasters can adjust the temperature, drum speed, and airflow to achieve the desired roast profile. This control allows for a wide range of roasting levels, from light to dark, and helps to develop complex flavor profiles in the coffee beans.

While drum roasting requires more manual attention to maintain consistency compared to hot-air roasting, it offers a slower roasting process that allows for more nuanced adjustments during roasting. This results in coffee beans with deep flavors, rich body, and balanced aftertaste.

In terms of energy efficiency, drum roasting can be less efficient than hot-air roasting due to the time required to heat the metal drum and maintain temperature. However, well-insulated drum roasters and appropriate batch sizes can help improve efficiency.

Overall, drum roasting is a method that is appreciated for its control over the roasting process and its ability to create complex flavor profiles. If you’re looking to experience the rich body and deep flavors that drum roasting can offer, be sure to try coffee beans roasted by experts like Daniel Horbat at Sumo Coffee Roasters.
