Scientists Discover Heightened Water Jet Improves Coffee Brewing Efficiency

New research highlights how a concentrated water stream enhances flavor extraction in filter coffee, addressing cost and environmental challenges.

Physicists from the University of Pennsylvania found that pouring water from a height in a concentrated stream strengthens filter coffee extraction by improving mixing dynamics.
The technique creates a 'lawine' effect, circulating coffee grounds and allowing water to penetrate deeper, resulting in a stronger brew.
Rising coffee prices have driven efforts to optimize brewing methods, enabling stronger coffee with less powder, aligning with consumer and environmental priorities.
Laser-illuminated particle experiments conducted in kitchen settings provided new insights into the physics of coffee brewing, blending science and tradition.
Global coffee consumption continues to rise, but climate change threatens supply chains with shrinking growing areas and increased extreme weather events.
