The Physics Of Filter Coffee Epub Updated -

Old physics models (pre-2020) assumed that uniform particle size leads to uniform extraction.

For a decade, baristas believed fines (particles <100µm) always clog filters and cause bitterness. the physics of filter coffee epub updated

"The Physics of Filter Coffee" by Jonathan Gagné remains the definitive guide on the subject, covering essential topics like percolation, water chemistry, and grind dynamics. New 2025 research from the University of Pennsylvania expands on this by identifying that a high-pouring laminar stream induces an "avalanche effect" in the coffee bed for improved extraction.

When hot water first hits fresh coffee, it fizzes and swells. This is the "bloom."
