Hario Switch recipe and dial-in guide

This is where Cuplift starts a new Hario Switch brewer before it knows anything about the coffee. Once you add a bean, the recipe adjusts for roast, process and altitude, then learns from what you taste.

Grind is in microns because a click means something different on every grinder. 720µm is about 24 clicks on a Comandante C40. Filter: V60 Paper (x1).

Steps

1. Rinse filter
2. Place on Switch (valve closed)
3. Add 15g coffee at 720µm
4. Bloom with 40ml at 93°C, swirl, wait 45s
5. Pour to 250ml in slow circles by 1:30, at 0:45
6. Steep at 1:30
7. Open valve at 2:30
8. Finish by ~3:30

The Hario Switch is an immersion brewer, which decides which changes are open to you.

• Grind leads, but steep time is almost as direct — and it has no side effects to untangle.
• Stirring speeds extraction and stirs up fines; agitate less if the cup turns muddy.
• Temperature and water minerals come after grind and time.

Whatever the problem, change one thing per brew. The dial-in guide covers the order to fix things in.

• Why does my coffee taste bitter? How to fix it
• Why does my coffee taste sour? How to fix it
• Why does my coffee taste dry, chalky or astringent?
• Coffee too strong or heavy? How to lighten it
