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…

Vihi & The 4R Framework: A Systemic Sustainability Strategy from Material Science to Circular Economy
Vihi & The 4R Framework: A Systemic Sustainability Strategy from Material Science to Circular Economy Sustainability is not a marketing claim. In environmental engineering, sustainability is a systemic equilibrium between materials, energy, product functions, and their ecological consequences. As a design studio specializing in coffee tools and 3D-printed engineering structures, Vihi embeds the 4R principles…

Turning Mystery into Engineering: How Vihi Redefines Pour-Over Coffee
Turning Mystery into Engineering: How Vihi Redefines Pour-Over Coffee In many parts of the coffee community, pour-over brewing is often described as “unpredictable.” Same beans, same steps — different results. But in engineering, unpredictability simply means a variable that has not yet been measured. At Vihi, our mission is clear: We turn what once felt…
