Great pour-overs are less about fancy gear and more about how water moves through coffee. Gentle, predictable flow extracts sweetness without haze; too much turbulence churns up fines and bitterness.
What Flow Actually Does
- Faster flow with a narrow stream increases local agitation; slower, wider streams spread energy.
- Tall pours hit harder; low pours are gentler.
- Pulses reset drawdown and redistribute heat; a steady pour stabilizes extraction.
Practical Targets
- Start with 1:16 ratio, medium grind.
- Bloom 40–60 s with 2–3x dose water; quick stir or two taps to wet dry pockets.
- Keep pour height low after bloom—about 2–4 cm from bed—for cleaner cups.
- Use small pulses (60–100 g) to maintain a shallow bed and consistent flow.
Dripper Nuance
- V60 (cone): Responds strongly to pour technique; narrow, controlled circles help avoid sidewall adhesion.
- Kalita (flat): Even bed depth tolerates slightly higher agitation; great for clarity with modest swirls.
- Origami: Similar to V60 but channels easily if wall-wetting is uneven—keep pours centered and low.
Swirls and Stirs
- A gentle end swirl smooths the bed and reduces channeling. Overdoing it pulls fines upward and slows drawdown.
- If drawdown stalls, slightly coarsen grind or reduce pour energy rather than stirring aggressively.
Tuning by Taste
- Hollow/under: finer grind or slightly taller stream; extend contact time by 10–15 s.
- Bitter/muddy: coarser, lower/fatter stream; reduce late pulses and skip end swirl.
- Thin body: bump ratio to 1:15 or add a small mid-brew pulse.
Reference Recipes
- V60 15 g → 250 g water: Bloom 40 s with 45 g; then 3 pulses to 150/210/250 g, finish ~2:45–3:10.
- Kalita 20 g → 320 g: Bloom 60 g, then two 130 g pours; swirl once at 2:00; finish ~3:20.
