Iced

Hario Switch 02 Hario switch by Hario

Hario's community method for the Switch 02 creates flash iced coffee from a concentrated closed-valve infusion released onto ice. Fine grinding and energetic extraction support a bright, clean cup after rapid chilling and dilution.

Notes

Set 120g in the server before wetting the coffee, then release the concentrate directly onto it. Stir until the drink is evenly chilled; if flavor is harsh after dilution, coarsen slightly rather than lowering the ice load.
