Switch Iced

Hario Switch 02 Hario switch by Hario

Hario Europe's Switch guide uses concentrated hot immersion followed by release over ice for a flash-chilled cup. The method trades brew water for immediate dilution, preserving bright aromatics, clean flavor, and refreshing intensity.

Notes

Place 150g in the server before releasing and use freshly frozen, neutral-tasting cubes. Swirl after drawdown to equalize dilution; if the result is thin, grind finer or extend immersion rather than reducing the ice.
