[L]eave it to a group of college students to find a way to make sure their beer is always free. Well, at least the recipe they use to brew it is. A group of students at IT University of Copenhagen have produced what they claim is the first open-source beer.

The recipe and brand of their beer is published under a Creative Commons license, which means anyone can use the recipe for pleasure or profit.

The only catch: If you make money selling their unique beer, you have to give them credit and publish any changes you make to the recipe under a similar license.
