BeanSieve
BeanSieve is a whole-bean sizing workflow that makes dose composition more intentional before grinding.
BeanSieve is a whole-bean sizing workflow that makes dose composition more intentional before grinding.
A weighed coffee dose can still be physically inconsistent if the mix of bean sizes changes from brew to brew. BeanSieve makes that hidden difference visible before grinding.
BeanSieve helps control the whole-bean size profile that enters the grinder and therefore the physical makeup of the dose before extraction begins.
- Roasted coffee is separated into retained size fractions.
- Each tray is weighed so the sample’s size profile becomes visible.
- The BeanSieve calculator turns those tray weights into matched or intentionally shifted dose plans.
- Prepared doses then stay visible as receipts so the next dose can be planned from what is actually left.
- When you want recipe tests to start from a steadier physical dose baseline.
- When limited competition samples need to teach something with each brew.
- When you want to compare coffees or recipe changes without letting dose composition drift unnoticed.
- It does not measure extraction, taste, roast color, or density by itself.
- It does not guarantee a better cup in every context.
- It does not replace good grinder, water, and dial-in decisions.
- It is less useful if the brewer does not intend to compare brews carefully enough for dose composition to matter.
- It does not eliminate weighing discipline; the workflow still depends on accurate tray entry, honest sample handling, and careful follow-through during dose planning.
- BeanSieve is designed as a 3D-printable tray system and companion calculator workflow.
- Use the current tray order and aperture guidance published in the how-to and app surfaces.
- Session accuracy depends on careful weighing and honest tray entry, not only on the hardware.
Testing
BeanSieve matters most when brewers need a matched starting point across a sequence of AeroPress brews and want the grinder input to stay more intentional.
Brew Supply is independent and not affiliated with AeroPress or the World AeroPress Championship. Printed parts used around coffee preparation should be produced, cleaned, and handled with appropriate food-contact caution.
No. Competition prep is a strong use case, but any brewer who wants more intentional, comparable dose composition can use it.
No. It does not change the roast itself. It changes how the roasted sample is selected and recomposed before grinding.
