Coffee Sieves & Sieve Shakers

About Coffee Sieves & Sieve Shakers

Coffee sieves and sieve shakers help you measure and control particle size at every stage of production, from grading green beans by screen size to checking a finished grind for consistency. This collection covers hand sieves and motorized shakers in 8", 10", and 12" sizes, built to ASTM C136 standards for repeatable lab results. If you are outfitting a full quality control bench rather than a single tool, browse our coffee cupping lab equipment collection for the scales, moisture meters, and roast analyzers that work alongside these sieves.

Why Sieve Testing Matters for Coffee Quality

Even particle size is what makes extraction predictable. When a grind runs too fine or too coarse in spots, some particles over-extract while others under-extract, and the cup tastes inconsistent batch to batch. A quick sieve test tells you exactly how your grind distribution looks, so you can catch a slipping grinder before it affects a full production run. Pair a sieve test with a check of your grinder settings, browse our coffee grinders collection if a burr or plate is due for adjustment or replacement.

Bean Grading Screens vs. Ground Coffee Test Sieves

This collection covers two different jobs, and it helps to know which one you need. Bean grading screens, like the 12" square wood sizing screens and stack holders, sort whole green beans by size in 64ths of an inch, the standard used for grading green coffee before roasting. Ground coffee test sieves work differently. They use stainless steel mesh in standard ASTM or Tyler designations to sort ground particles by micron size, which is what you want when you are checking grinder output rather than green bean size.

Hand Sieves vs. Motorized Sieve Shakers

A hand sieve set works well for spot checks. You shake a sample through a stack of mesh sizes by hand and weigh what settles on each screen. For labs running repeated tests through the day, a motorized sieve shaker built to ASTM C136 standards saves labor and keeps the shaking time and intensity consistent from one test to the next, which matters if you are comparing results across shifts or operators.
