AeroPress, inside out

Strip the folklore and the AeroPress is an immersion brewer with two upgrades: a paper filter, and a plunger that ends the brew on your schedule. The pressure is modest — a fraction of a bar, nowhere near espresso — but it pushes the finished brew through the paper in seconds, giving immersion's even extraction a clean, decisive finish. No drawdown to manage, no bed to read.

That is why the AeroPress tolerates almost anything: fine grind and ninety seconds, coarse grind and four minutes, scalding or barely hot. The variables still matter — it simply fails gently instead of catastrophically.
