Free Beer (Vores Øl)
Free Beer, formerly known as Our Beer (Danish: Vores øl) is the first brand of beer with a "free" recipe - free as in "freedom", taken after the term "free software". The name "Free Beer" is a play on Richard Stallman's common explanation that free software is "free as in speech, not free as in beer." The recipe is published under a Creative Commons license, specifically the Attribution-ShareAlike license.
The beer was created by students at the IT-University in Copenhagen together with Superflex, a Copenhagen-based artist collective, to illustrate how concepts of the free software movement might be applied outside the digital world.
