UFO Dripper V3 01

The UFO Dripper V3 01 from UFO Coffee Tools is the size 01 version of the V3, built around the same 80 degree interior angle and negative channel structure as the larger model, sized for doses in the 1-2 cup range. It brews on its own as a percolation dripper, and it sits directly onto a Hario Switch base when you want to hold the water instead.

The Story Behind It

The V3 line is built on one decision: open the cone from the 60 degree angle most conical brewers use out to 80 degrees. A wider wall means a shallower bed, and a shallower bed means the depth of the coffee barely moves when the dose does. That is what makes a conical repeatable in the way a flat bottom usually is, without giving up the clarity and acidity people brew conicals for in the first place.

Inside the cone, the wall carries negative channels instead of protruding ribs. The paper seats against a smooth surface rather than clinging to a rib, so airflow stays even and pressure equalizes above and below the brewer. In the 01, that structure sits around a smaller chamber, which is the whole point of this size: the geometry that keeps drawdown stable, on a size that suits the amount of coffee you are actually brewing.

Tritan, and Why the Material Matters Here

The body is Tritan, a food safe copolyeste. It is BPA free, it resists warping at boiling temperatures, and it conducts heat far less readily than metal or glass, so the slurry holds its temperature more steadily through the pour. On a smaller dose, where thermal loss shows up faster, that stability does more work than it does at volume.

Product Details

Geometry That Guides Extraction

The 80 degree interior angle promotes steady drawdown while keeping the bed evenly saturated. It supports efficient flow through the coffee, reduces channeling, and minimizes stall. Nothing here restricts flow mechanically or forces it: the structure itself regulates how water moves.

The same geometry widens the useful grind range. Extraction stays controlled and predictable, so a change in grind size or pour translates clearly into the cup. Profiles stay expressive and structured.

Negative Channels and Flow Stability

The negative channel design supports balanced airflow during drawdown, preventing vacuum lock and reducing turbulence. By stabilizing the brew bed and evening out water distribution, it holds clarity and a controlled flow. Drawdown is faster and consistent, and balance stays intact.

A Chamber Sized for Smaller Doses

The smaller brew chamber of the UFO V3 01 favors smaller brews and the precision that comes with them. It takes doses of roughly 12 to 18 grams on a bed surface that will feel familiar if you have brewed a size 01 conical before. There is still room to move between lighter, clarity focused brews and fuller extractions without destabilizing the bed.

The Silicone Base

The base of the UFO V3 01 is silicone rather than rigid plastic, so it has some give and sits softly on a server or cup. It detaches easily, which is what makes the hybrid setup below possible.

Percolation or Immersion, From One Brewer

On its own, it works as a percolation dripper with stable flow. Take the silicone base off and seat the cone on a Hario Switch base, and it becomes a hybrid immersion brewer. In that configuration you can extend contact time, hold water before releasing it, and deliberately push extraction deeper. The geometry that keeps percolation clean also keeps the immersion drawdown controlled once the valve opens.

One brewer, two distinct extraction approaches, without adding complexity to the workflow.

Filter and Base Compatibility

The 01 takes UFO Type A 01 filters, Type F 01 filters, and the Sibarist FAST UFO Special Edition in size 01. It seats on a Hario Switch base for immersion brewing, and on the included silicone base for standard percolation.
