This research poster traces the global genealogy of coffee-brewing technologies—from early filtration practices in the Ottoman Empire and eighteenth-century Europe to twentieth-century paper filters, siphons, espresso machines, and the emergence of Japanese craft traditions—culminating in the development of the Hario V60 hand filter. It situates the V60 within a long lineage of experimentation between laboratory science and domestic practice, showing how material innovation, environmental production methods, and design engineering (such as spiral ribs, a 60-degree cone angle, and controlled flow dynamics) shaped its rise as a flexible, precision-oriented brewing device.

The study further connects technological evolution to cultural shifts in coffee consumption, mapping the so-called “waves” of coffee culture—from industrial mass beverage to lifestyle product, sustainability-driven specialty coffee, and today’s scientifically optimized brewing scene. By weaving together design history, industrial strategy, and consumer culture, the project demonstrates how a seemingly simple object became a global standard for contemporary coffee practice.
