# Corrections and substantive updates

Found an error? Send the page URL, the relevant passage and, if possible, a primary source to [info@wi4.nl](mailto:info@wi4.nl).

## How a correction is assessed

We compare the report with the cited sources and the exact regional version. A manufacturer source, manual or research paper helps assess factual errors. Differences in taste are distinguished as preferences or advice.

## Publication dates and updates

Publication dates are shown only when known and supported. A substantive update date changes only after a material revision, such as corrected product information or revised brewing advice. Deployment, CSS changes and template changes are not substantive updates.

## Finding material corrections

For a correction that changes the meaning or buying advice, we add a note to the affected page describing what changed and why. Minor typographical corrections do not receive a new substantive update date.
