The Origami Dripper is a Japanese ceramic or resin dripper designed by Takahiro Shirota and produced by Trunk Coffee in Nagoya. Its defining characteristic is the 20-ridge interior, which creates air channels allowing the dripper to accept both flat-bottom (Kalita-style) and conical (V60-style) filters — a flexibility that no other mainstream dripper offers. That versatility is not a gimmick: each filter shape produces a meaningfully different cup from identical inputs, making the Origami a genuinely multi-purpose tool rather than a marketing claim.
Tetsu Kasuya used an Origami Dripper when he won the 2016 World Brewers Cup Championship — the competition that brought the dripper to international attention. The brewer has since been adopted widely in competition and café contexts globally.
Equipment and Filter Options
The Origami Dripper comes in two sizes: Small (1–2 cups, using 13–15 g coffee) and Medium (2–4 cups, 20–25 g coffee). Both sizes accept:
- Conical filters (Hario V60 size 02, Cafec Abaca, Sibarist): These concentrate flow to the center and produce a brighter, more aromatic cup with slightly less body.
- Flat-bottom filters (Kalita Wave 155/185, April Brewer flat): These distribute extraction across the entire bed, producing more even saturation, fuller body, and a rounder mouthfeel.
The ridges are what make dual compatibility possible — they hold the filter off the dripper wall, allowing airflow and drainage regardless of filter shape. This matters most with flat-bottom filters, which can suction to smooth-walled drippers and restrict flow.
The Origami sits on a separate glass or stainless ring stand sold alongside it (the “Origami stand”). The stand elevates the dripper above your server with enough clearance to watch the flow rate.
Ratios and Grind
Standard ratio: 1:15 (20 g coffee to 300 ml water for the medium).
- With conical filters: medium-fine grind (slightly coarser than V60 standard, around Comandante 24–26 clicks).
- With flat-bottom filters: medium grind (Comandante 27–30 clicks). Flat beds distribute flow more evenly, so finer grinds can create channeling issues.
Water temperature: 92–94°C for light roasts, 88–91°C for medium and dark.
Technique with Conical Filter
- Rinse the filter with hot water, discard rinse water.
- Add 20 g of medium-fine coffee.
- Start timer. Pour 40 ml water for bloom; stir gently or swirl.
- At 0:45, pour to 150 ml total in a slow, steady spiral.
- At 1:30, pour to 250 ml.
- At 2:00, pour to 300 ml.
- Target drawdown complete by 3:30–4:00.
Technique with Flat-Bottom Filter
Flat-bottom technique requires less aggressive pouring to avoid channeling through the flat bed.
- Rinse filter. Add 20 g of medium coffee.
- Pour 50 ml bloom water, gently swirl the dripper (not the stand), wait 45 seconds.
- Pour steadily to 200 ml by 1:30, keeping the pour centered.
- Pour to 300 ml by 2:15.
- Target drawdown: 3:30–4:30 total.
Why the Origami Won at WBC
Kasuya’s 2016 recipe used the Origami to showcase a specific Kenyan coffee’s layered flavor profile. The competition context required consistent, reproducible results under time pressure — and the Origami’s combination of forgiving ridge geometry (which prevents suction-sealing) and flat-bottom capability gave him extraction control that V60 alone couldn’t provide. Since then, competitors have used it repeatedly because its dual-filter compatibility lets them tune the cup to the coffee rather than the other way around.
Ceramic vs. Resin
The Origami is available in ceramic (Mino ware, Japan) and MHPC resin. Ceramic retains heat better during longer brews and is preferred for café use. Resin is lighter, unbreakable, and performs equivalently for home use. Both share identical geometry.
Troubleshooting
- Channeling, uneven extraction with flat-bottom filter: Reduce pour speed, keep the pour centered, and avoid pouring directly on the filter walls.
- Slow drawdown past 5 minutes: Grind is too fine for the filter type. Coarsen by 2–3 steps and retest.
- Flat or underdeveloped cup despite correct time: Increase water temperature by 1–2°C or stir the slurry at bloom more aggressively.
- Conical filter collapsing inward: Filter is the wrong size. V60 02 for medium Origami, V60 01 for small.
