Start here: 20 g medium coffee · 320 g water · water around 93–96°C / 200–205°F · roughly 3–4 minutes.
The method
- Rinse the paper filter with hot water and discard the rinse. Add coffee and level the bed.
- Pour 40 g water over the grounds and wait 30–45 seconds.
- Pour slowly in small circles until you reach 320 g total water. Keep the bed covered without filling to the rim.
- Let the water drain, remove the filter, and swirl the brewed coffee before serving.
Adjust: A sour, thin cup may benefit from a slightly finer grind. A dry, harsh cup may benefit from a coarser grind. Timing varies by brewer and filter.
