Lecture Description

This lecture will report on recent progress from the Zurich University of Applied Sciences on the science and technology of coffee grinding. First, we will introduce a methodology for benchmarking high-end parallel burr coffee grinder. A set of parameters will be defined and validated. In particular, the role of ground retention inside the grinder will be highlighted, as a central criterion to assess the performance of grinder. Second, we will explore the impact of particle size distribution of coffee grounds on espresso extraction, with a particular focus on the share of fine.
