What each ingredient does
- Ground coffee
- Supplies the flavour compounds that the hot water extracts into the brew.
The step that matters
Percolate for the right time. The brew cycles repeatedly through near-boiling water, so extraction keeps going. Percolating too long over-extracts bitter compounds, while stopping too early leaves the coffee weak. Stay within the 5 to 8 minute window.
