The most common pour over ratio is 1:15 to 1:16 — meaning 1 gram of coffee per 15–16 grams (ml) of water. For a balanced 8 oz cup, you'd use about 15–16 grams of ground coffee. Adjust to taste: go higher (1:18) for a milder cup or lower (1:13) for something more robust.
Water temperature depends on your roast level. Light roasts extract best at 199–205°F (93–96°C), medium roasts at 194–200°F (90–93°C), and dark roasts at 188–194°F (87–90°C). Using cooler water for darker roasts prevents over-extraction and bitterness.
Pour over methods like the V60 and Chemex work best with a medium-fine grind, similar to coarse sea salt. French press and cold brew call for a coarser grind, while moka pot needs a fine grind. Grind size controls flow rate and extraction, so matching it to your method is essential.
A typical pour over brew takes 3–4 minutes from the first pour to the last drip. A faster brew (2–3 min) produces a lighter, milder cup, while a slower brew (4–5 min) extracts more and yields a stronger, more robust flavor. Adjust your grind size to control brew speed.
Chemex recommends a ratio of about 1:15 to 1:17. Because the Chemex uses a thicker filter, it produces a cleaner, brighter cup — a slightly coarser medium-fine grind and a 4–5 minute brew time works best. Start with 1:16 and adjust from there.
French press typically uses a 1:12 to 1:15 ratio with coarsely ground coffee steeped for 4 minutes. The immersion brewing method extracts more oils and body than pour over, so many people prefer a slightly coarser grind and a ratio around 1:14 for a full-bodied result.
Roast level affects extraction efficiency more than dose. Darker roasts extract more easily, so you can use slightly less coffee or lower water temperatures to avoid bitterness. Light roasts are denser and benefit from hotter water. The ratio stays roughly the same, but temperature fine-tuning matters.
Yes — select Cold Brew as your method. Cold brew uses a much higher ratio (1:8 to 1:12) since it brews as a concentrate, and it uses room-temperature or cold water. No heating required. Steep for 12–24 hours and dilute to taste before serving.
