Hario Switch
Hario Switch 02
Steps
Place a V60 02 paper filter in the Switch and close the valve. Pour 150 g of hot water, wait 30 seconds, then open the valve and drain into the server. Discard the rinse water. Close the valve again, add the coffee and start the brew within 30 seconds.
With the valve closed, pour to 50 g and swirl until all the coffee is wet.
Keep the valve closed and pour steadily to 175 g. Swirl gently; the Switch 02 is close enough to full that stirring is not needed. Cover the top with a small plate during the closed steep.
Open the valve and let the immersion phase begin to drain.
When the water level is about halfway down, pour slowly in the centre to 230 g. Keep the level below where it was when you opened the valve.
The brew should finish around 3:15-3:45. It is done when the coffee-bed surface shows and the flow turns to drops.

Technique
Preheat the glass thoroughly, keep agitation gentle and use the valve timing as the main control point. Treat the recipe as a starting point and adjust after tasting.
Pouring tip
Use the glass cone as a visual guide. Keep the level controlled, and make valve changes only after the stated time and visual cue are both satisfied.
