Methanol (CH₃OH) is actually slightly more acidic than water (H₂O), but the difference is relatively small.

The acidity of a substance is typically measured by its pKa value, which is a measure of the strength of an acid. A lower pKa value indicates a stronger acid. The pKa value of methanol is around 15.5, while the pKa value of water is around 15.7. This means that methanol is slightly more acidic than water, but the difference is relatively small.
