The Physics of Filter Coffee grinder and a unique aromatic rangeThe Physics of Filter Coffee by astrophysicist Jonathan Gagn is perhaps the most significant book ever written on the science of coffee brewing.

He takes the reader down such rabbit holes as pouring kettle design, optimizing turbulence while pouring, the impact of fines on percolation, the physics of paper filters, and the geometry of
