Most grinder discussions get stuck on unproven claims: “cutting burrs taste cleaner, crushing burrs taste muddy.” At Coffee Analytica, we believe coffee conversations should rest on measurable evidence - not marketing stories.

The truth is simple: the only defendable way to judge a grinder is by its particle size distribution (PSD) and its repeatability in extraction. Research shows that tighter PSD improves uniformity, reduces waste, and makes café recipes reproducible. What has not been proven is whether burr “cutting” versus “crushing” directly changes cup quality in a consistent, measurable way.

This blog calls out the difference between evidence, assumptions, and speculation. We break down what’s proven, what’s partially supported, and what remains unverified. Grinder evaluation should live in the world of engineering judgment and controlled testing, not anecdotes.

At Coffee Analytica, we exist to close this gap - turning coffee myths into measurable truths.
