This Little Coffee Tool Fixes a V60 Problem You Didn't Know You Had - Yanko Design
"This is a precision metal tool designed to seal your V60 paper filter against the dripper walls before you add a single gram of coffee. The Presso itself is a fanlike arrangement of metal fins on a tapered handle, angled at exactly 60 degrees to match the V60's cone geometry. You lower it into an empty rinsed filter, the fins press the paper flush against the dripper walls, and then you add your grounds on top."
"When a filter loses contact with those walls mid-brew, water bypasses the coffee bed through the gap, extraction goes uneven, and the cup suffers in ways that are genuinely difficult to diagnose through the usual variables. The Presso closes that bypass before the brew begins, and the gaps between the fins keep water moving freely once it does."
"SAQ built it exclusively for the Hario V60, the most widely used dripper in specialty coffee, and that single-platform focus shows in the geometry. A 60-degree fin angle is not a design flourish, it is the V60's cone angle, and matching it exactly is what makes the seal work. A more generalist tool trying to serve every dripper on the market would have compromised on that precision, and the compromised version would have been considerably less useful."
A precision metal tool seals V60 paper filters against dripper walls before adding coffee. The Filter Presso uses a fanlike arrangement of metal fins on a tapered handle angled to match the V60 cone geometry. The tool is lowered into an empty rinsed filter so the fins press the paper flush against the dripper walls. This prevents water from bypassing the coffee bed through gaps mid-brew, which can cause uneven extraction that is hard to diagnose. After sealing, the gaps between fins allow water to move freely once brewing begins. The tool is built exclusively for the Hario V60, with a 60-degree fin angle matching the cone angle for reliable performance.
