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…
