Steep or flow
- Immersion keeps coffee and water together; percolation runs water through a bed and out.
- In a steep the clock leads, and extraction slows as it goes. In a cone the grind sets the pace.
- Steeping forgives the pour. Flow stops itself when drained and repays care with clarity.
Two ways to wet a coffee
Immersion keeps water and coffee together for the whole brew: French press, AeroPress, the mug method. Percolation sends water through the bed and out: the V60, the Chemex, every drip machine.
Same clock, different physics
Drag the clock. In the press, the water sits and darkens. In the cone, it arrives, passes through and leaves, like visitors round a stately home. Same coffee, same water, different physics.
Who’s in charge
In a steep the clock leads, and a forgiving one: as the water fills with coffee it pulls more slowly, so a late minute costs little. In a cone the grind sets how fast the water leaves, so it keeps strict time too.
The long end of a steep
Extraction in a steep never quite stops, which is the whole reason for decanting. A cone is the opposite: once it has drained, the brew is over.
As a steep goes on, extraction…
Answer: Slows, but never quite stops. It slows, because the water fills with dissolved coffee — but it never stops, which is why you decant.
Put the brewers away
Which kind is each brewer?
- Steep
- French press
- The mug method
- Flow
- V60
- Chemex
- Drip machine
The press and the mug hold everything together; the V60, the Chemex and a drip machine run water through and out.
What each one forgives
Steeping forgives a wobbly pour and a minute’s distraction. Its weak spots: forgetting to decant, and the grit a press mesh lets through. At the kettle, flow is as forgiving as a tax inspector — but through paper it gives you clarity.
Walk away after the last pour
The last pour is in, the kettle is down, and the phone rings. It is a long call.
The last pour is in and you wander off for half an hour. Which brewer forgives you?
Answer: The cone — it drains and stops. The cone. Once it has drained the brew is over; a press keeps steeping, so it wants decanting.
The best of both
Some brewers cheat, politely: an AeroPress steeps first, then presses through paper. A pour-over is the other end — all flow, all you. Steep before your eyes are open; pour when you have ten quiet minutes.
“Neither brewer is the better, I find, merely the more suitable.”
