01
Choose version.
Use AeroSweep Chaff if you only want chaff removal. Use AeroSweep Fines if you want chaff removal plus partial fines trapping.
Version rule
Chaff has a flat floor. Fines has a printed fines-trapping floor.
Variables to control
Separation surface
Before
Blow chaff from a narrow catch cup
After
Expose the grounds on a wider tray
Fines handling
Before
Keep or remove fines with a separate workflow
After
Optionally trap some fines during the same chaff-removal step
Key benefits
Ground-coffee preparation tray that makes chaff removal and optional fines trapping easier to repeat.
- Wider tray gives airflow more exposed surface area than a catch cup.
- AeroSweep Chaff has a flat floor for chaff removal only.
- AeroSweep Fines has a printed floor that can trap some fines during shaking.
- Prototype testing retained roughly 1–3 g of fines from a 20 g dose, depending on shaking.
- One workflow can handle both chaff removal and partial fines trapping at the same time.
- Does not replace a dedicated sieve or define an exact micron range.
How to use it
The main workflow, kept simple.
This is the core guide. Everything else on the page supports these five steps.
02
Add ground coffee.
Grind your coffee, then pour the grounds into AeroSweep. Spread the grounds across the tray so more surface is exposed.
Setup rule
Keep the tray open while blowing out chaff. The grounds need exposure for airflow to work.
03
Cap and shake.
Place the cap on AeroSweep before shaking. The cap keeps the grounds inside the tray while you move them side to side.
Handling rule
Use the same cap position, airflow, and shake pattern when comparing brews.
04
Trap fines if needed.
With AeroSweep Fines, use about 15 gentle side-to-side shakes as a starting point. More shaking usually traps more fines.
Fines rule
Shake count is a rough control, not a measurement.
05
Transfer to AeroPress.
Use the spout to pour the prepared grounds into the AeroPress chamber. If you used AeroSweep Fines, decide whether to leave the trapped fines behind or recover them before brewing.
Transfer rule
Keep the movement controlled so the prepared dose stays together.
Quick version guide
Two versions. Same basic workflow.
Choose the version that matches the preparation state you want to test.
Fast check
Use Chaff when you want the grind distribution mostly untouched.
Use Fines when partial fines trapping is part of the test.
Start with about 15 gentle side-to-side shakes.
Use a similar shake count when comparing brews.
Use a dedicated sieve if you need exact particle-size separation.
Why use it?
Make the separation step less improvised.
Want to experiment?
Treat AeroSweep as a preparation variable.
Compare one state at a time:
- • no separation
- • chaff removal only
- • chaff removal plus partial fines trapping
- • fewer shakes
- • more shakes
- • trapped fines discarded
- • trapped fines mostly recovered
Keep the rest of the recipe stable.
Companion note
AeroSweep Chaff is for airflow-based chaff removal.
AeroSweep Fines is for chaff removal plus partial fines trapping.
A dedicated sieve is still better for exact particle-size separation.
Use the tool that matches the level of control you need.
