You may be thinking of Coffee: To Freeze or Not to Freeze and its follow-on discussion:
Ken Fox and Jim Schulman repeated the experiment described in this article in March of 2009, with some modifications that extend the usefulness of the results to include lower dosing, a longer interval of freezing, and the use of higher end grinders. They published their results in the forums under the title of Freezing Espresso Coffee, Part Two. Jim elaborated on how to correctly interpret the results of such experiments in A note on comparison tests.
