Origami Dripper: Ultimate Field Guide to Geometry, Filters, Flow, Grind & Recipe Matrix (with Troubleshooting)

1) Geometry First

Origami’s petal ribs deliver high clarity—but only if air channels stay open. Paper angle variance from stacked packaging can cause sticking and collapse. Pre-shape the paper to normalize pleats before brewing.

Tip: Pre-form with a shaping tool (e.g., V-Fold) for even angles; then seat the paper carefully so each rib has contact without choking channels.

2) Filter Papers: Types & Fit

• Hario V60 cone: very expressive; sensitive to pour pattern.
• CAFEC cone: usually faster; watch for early under-extraction.
• “Thicker” cones: slower, cleaner; raise grind or lower dose to keep time in range.

Rule: If time swings >±15 s between cups, the geometry (paper fit) is the first suspect—pre-shape, then re-seat.

3) Flow Targets & Timing

• Total time targets (15–18 g dose): 2:20–2:45 (±10 s).
• Too fast → finer grind or slightly higher bloom ratio; too slow → coarser or gentler wall contact.
• Bloom: 25–40 g / 15–30 s; avoid hard wall impact on the first pour.

4) Grind Matrix

• EK43: 7.5–8.5 (light roast tilt finer; dark tilt coarser)
• 64-mm flat: espresso reference + 8–12 clicks outward
• Conical: set by time first (2:20–2:45), then taste trim

Feedback loop: If drawdown steady but flavor hollow → finer + smaller pulses; if astringent/flat → coarser + smoother pours.

5) Pro Recipes

Light roast clarity (18 g → 270 g, 94 °C)
Bloom 40 g / 30 s → three 75–80 g pours. Target 2:30–2:45.

Medium roast balance (16 g → 240 g, 93 °C)
Bloom 30 g / 25 s → two 100–105 g pours. Target 2:25–2:40.

Dark roast sweetness (15 g → 225 g, 92 °C)
Bloom 25–30 g / 20 s → gentle pulses 50–60 g each. Target 2:10–2:30.

6) Troubleshooting

• Collapse / sticking: pre-shape paper, reduce bloom mass, avoid early wall hits, slightly coarser grind. See our collapse guide.
• Random time swings: paper geometry first → re-seat; then adjust grind 1–2 notches.
• Sour / thin: finer grind, slightly hotter water, extend total time by ~10–15 s.
• Bitter / astringent: coarser grind, lower temp 1–2 °C, avoid over-agitation.
