Grinder and Burr Effects on Readings

Grinder choice and burr geometry can affect comparative readings when preparing roasted coffee for measurement or evaluation. One reported observation is that grinders/burrs such as Lagom MP, 98 mm SSP HU, and brew burrs may “read higher,” with the suggested reason being better particle uniformity and the ability to grind much finer. source

Practical Implication

When comparing readings between samples, keep the grinder and burr setup consistent where possible. Differences in burr type, grind fineness, and grind uniformity may shift readings even when the roasted coffee itself has not changed. source

Caution

The reported claim does not specify the exact measurement device or metric, so this should be treated as an operational note rather than a universal rule across all roast-color or analysis systems. source
