AeroPress (inverted)

The AeroPress upside-down so nothing drips out while it steeps. Full control over contact time, at the cost of a flip that can go badly.

Roast	Grind	Coffee	Water	Time
light	medium-fine	17 g	240 ml	2:30
medium	medium	17 g	240 ml	2:20
dark	medium	15 g	240 ml	2:00

Makes one 240 ml cup. The figures above are the whole recipe.

What goes wrong

Seating the plunger too shallow before inverting (it slips out mid-flip, hot coffee everywhere), overfilling past the rim (leaks on the flip), pressing hard to finish faster (forces fines through the paper, bitter and gritty)

Care schedule

1 task for this machine.

Replace the plunger seal

Yearly

The rubber seal is the only thing making an AeroPress a pressure brewer. Once it hardens the plunger slides too easily, air escapes past it, and the brew goes weak and thin with no obvious cause.

What you need

A replacement seal for your model - the XL seal is not the standard one. Warm soapy water.

What goes wrong

Storing it compressed, which flattens the seal within months. Diagnosing weak coffee as a grind problem when the seal is passing air. Buying the wrong model's seal. Putting oil or grease on the rubber, which swells it.

The procedure

Test the old one first. Seal the chamber with the filter cap and no filter, insert the plunger 2cm, and press. It should resist. If it slides freely, the seal is done.
