Why the Same Dripper Never Brews the Same Coffee: An Introduction to Dripper Structural Engineering
Why the Same Dripper Never Brews the Same Coffee In pour-over coffee, one question keeps coming back: Why is it so difficult to reproduce the same cup, even with the same dripper and recipe? The common explanations often include: Inconsistent pouring technique Minor differences in water flow “Off days” From an engineering perspective, these explanations…

A Complete Breakdown of Random Variables in Pour-Over Coffee
A Complete Breakdown of Random Variables in Pour-Over Coffee Why do people call pour-over coffee “unpredictable”? Why can V60, Origami, or Kalita Wave produce completely different results with the same beans and recipe? The truth is simple: Pour-over coffee has too many invisible variables. At Vihi, we turn these unknowns into measurable engineering structures. 01｜Filter…

Dripper Structural Engineering: A Technical Whitepaper by Vihi Design
Dripper Structural Engineering: A Technical Whitepaper Vihi Design Coffee Research Lab ｜ Technical Whitepaper 2025 Preface: Why Dripper Geometry Matters More Than We Think A dripper is not simply a “holder for paper.” From an engineering perspective, it is a micro-scale fluid dynamics device. Its geometry determines: Flow rate Bed stability Pressure distribution Flow pathway…
