What does the acronym PEMME stand for in coffee roasting?

The acronym PEMME in coffee roasting stands for People, Equipment, Method, Material, and Environment. Each component plays a critical role in the roasting process.

• People refer to the skilled individuals who operate the roasting equipment and make crucial decisions during the roasting process. Their knowledge and experience directly impact the quality of the roasted coffee.

• Equipment encompasses the various machines and technologies used in the roasting process. The type of roaster, its settings, and maintenance affect the outcome of the roasting.

• Method refers to the techniques and processes used in roasting coffee, including the specific roasting profile, temperature control, and timing. The chosen method can influence flavor development and consistency.

• Material signifies the raw materials involved, particularly the green coffee beans themselves. Factors such as the origin, variety, and processing of the beans can significantly impact the flavor profile of the final product.

• Environment considers external factors such as humidity, altitude, and temperature that can affect the roasting process and the green coffee's characteristics.

Understanding PEMME helps roasters to create a controlled and repeatable environment that can lead to a high-quality end product. This holistic approach ensures that all aspects influencing roasting are considered for optimal results.
