Hario Switch

Method

For the Hario Switch, use 15 g medium-ground coffee and start with the switch closed. Pour 240 g water all at once and swirl to saturate; at 1:45 open the switch to drain. Aim to finish in ~2:45–3:15 for a rounder profile. If it tastes too heavy, open earlier (around 1:30) or go coarser; if it’s thin, open later or grind finer.

Steps

1. Switch closed; add 15 g. 
2. Pour 240 g water at once; swirl to saturate.
3. 1:45 Open switch to drain.
4. Finish ~2:45–3:15; rounder profile.

Fix it: Too heavy → open earlier (1:30) or go coarser. Thin → open later or go finer.
