2024 US Brewers Cup champion Weihong Zhang's recipe for the Hario Switch, which toggles between immersion and percolation mid-brew. With the valve open, add 50g at 80°C; close it at 0:40 and pour to 200g at 92°C, opening again at 2:10. The cooler immersion builds sweetness and body while the hotter percolation lifts clarity and aroma; the flat, star-grooved MUGEN bed curbs channeling and 100 ppm water keeps the cup clean.
