Epub Updated Hot! — The Physics Of Filter Coffee

$$Q = \frack \cdot A \cdot \Delta P\mu \cdot L$$

The first edition relied on a log-normal distribution of particle sizes. The updated text introduces a bi-modal PSD model based on 2024 laser diffraction data from the Swiss Grinding Institute. This explains why expensive grinders (with tight PSD) produce sweeter coffee: they eliminate the "fines paradox" where extremely small particles over-extract bitterness while large particles under-extract sourness. the physics of filter coffee epub updated

Where $k$ = permeability (depends on grind size), $A$ = bed area, $\Delta P$ = pressure difference, $\mu$ = water viscosity, $L$ = bed depth. Find published within the last year on that specific topic
