Tricolate Brewer: No-Bypass Coffee, No Pour Technique

The Tricolate is an Australian no-bypass brewer that removes two hard parts of pour-over: where the water goes, and whether all of it meets the coffee. A dispersion screen rains water evenly over a flat bed, while sealed vertical walls prevent water from slipping around the grounds. The result is a high-extraction filter cup with little pour technique and a longer, slower drawdown.

A Shower Screen And Sealed Walls

The Tricolate is built around hardware distribution. You pour into the screen, and the screen spreads water at a fixed height and flow across the whole bed. That is why a gooseneck kettle is not essential here; dramatic pouring is not the skill the device asks for.

Below the screen, the straight sealed walls do the second job. In a cone brewer, some water can travel down the filter wall and dilute the cup without passing through much coffee. That shortcut is bypass. In the Tricolate, water has to pass through the coffee bed. For the concept behind this family, see no-bypass brewing.

The trade-off is consumables and pace. Tricolate uses proprietary flat papers, not mainstream cone or basket filters, and normal brew times are longer than a quick V60.

What No Bypass Does To The Cup

No-bypass brewing can make light roasts taste dense, sweet, and complete because the same amount of water extracts more from each gram of coffee. That is why Tricolate recipes can look strange: 1:20 or 1:22 can still taste strong enough when extraction is efficient.

The counterintuitive grind lesson matters most: coarser is not always faster in this brewer. The inventor's guidance is that coarse settings can create boulders and migrating fines that clog the flat bed. If a Tricolate brew runs 10-15 minutes and tastes dull, the fix is often to grind finer, improve bed prep, and break up clumps, not to rush coarser.

This is different from ordinary pour over, where a coarser grind often speeds drawdown. The Tricolate rewards evenness more than showy technique.

From Adelaide To The No-Bypass Wave

The Tricolate was invented by Dan Shusett in South Australia and became one of the first widely discussed no-bypass brewers. Its name comes from an older coffee maker called the Tricolator, not from a blend of "Tritan" and "percolate," even though the modern brewer is made from Tritan plastic.

It sits in the first generation of modern no-bypass devices. The NextLevel Pulsar adds a flow-control valve to a similar zero-bypass idea. The Orea Brewer lives nearby as a low-bypass flat-bottom brewer, and the Hario V60 remains the opposite pole: more pour skill, more bypass, more traditional pour-over feel.

Brewing With A Tricolate

1. Rinse the flat paper and preheat the brewer. A cold body slows an already slow brew.
2. Add 15-20 g of coffee ground medium-fine, generally finer than V60.
3. Level the bed carefully. Clumps matter more here than pour patterns.
4. Attach the dispersion screen before adding water.
5. Bloom with about 2.5 times the coffee weight in water through the screen, then swirl firmly to wet the bed and release trapped gas.
6. After 45-60 seconds, add the rest of the water through the screen. A single continuous pour is usually enough.
7. Let the brewer drain. Five to ten minutes can be normal.
8. If the brew is thin at 1:22, shorten toward 1:19 or 1:20. If it stalls badly, inspect bed prep and consider grinding finer before assuming coarser is the cure.

The Taste, And Who It Suits

Dialed in, Tricolate coffee is clean, sweet, concentrated, and unusually complete for a filter method. It suits extraction-curious brewers, light-roast drinkers, people who want repeatability without pour choreography, and anyone intrigued by high-yield filter coffee.

Skip it if you want fast morning coffee, cheap filters everywhere, or the meditative craft of gooseneck pouring. The Tricolate deliberately deletes part of that craft. That is either its appeal or the reason to choose another brewer.

Bottom Line

The Tricolate is not a normal pour-over with a different shape. Its screen handles water distribution, its walls remove bypass, and its grind logic can run opposite to intuition. Treat it as a no-bypass brewer, not as a cone, and judge success by sweetness and evenness rather than speed.
