Hario Alpha 01

Long Bloom

Hario Alpha 01 Hario others by MataCafe

MataCafe, a shop in Tamsui, published two schedules when they took the Alpha apart on camera. This is the tighter one: a small wet, a full fifty seconds of rest, then three identical pours poured back to back with no pause between them. The long rest does the degassing work up front so the three later pours can run continuously without the bed rising.

Notes

The fifty-second rest is the whole idea — it is roughly twice a normal bloom, and it is what lets the rest of the brew run without stopping. Once you start the second pour, keep going: three equal additions, one straight into the next, each taking about twenty seconds. The 71.4g/L ratio is on the concentrated side, so if the cup reads heavy, take the water up before you touch the grind.

Grinder

52 on their Alpha grinder.
