Free Beer, originally known as Vores Øl (English: Our Beer), is a Danish brand of beer that markets itself as being the world's first open-source beer. The beer was created in 2004 by students at the IT University of Copenhagen and the artist collective Superflex, to illustrate how concepts of the FOSS movement might be applied outside of the digital world. In contrast to the practice of trade secrets, the Free Beer brand advocates for the free sharing of recipes and formulas, analogizing it to the FOSS movement's open sharing of software and source code. Free Beer operates by sharing its recipe and trademark elements under the Creative Commons CC BY-SA license, with breweries and individuals. History Vores Øl In December 2004, a group of IT University of Copenhagen students and Superflex brewed a 100-litre batch of dark heavy beer in their school's cafeteria. The group labelled the beer Vores øl (Danish for Our Beer) after a 1994 Carlsberg beer advertisement slogan. A website was created to promote the project, and the beer's recipe and label designs were published under an open-source Creative Commons license, specifically the CC-BY-SA 2.5 license. Unlike software, cooking recipes aren't copyrightable, so the share-alike/copyleft licensing approach is legally questionable and untested in court. After its publication, the project received an overall positive reception from the international press and media for the political message. Concept extension Free Beer The developers of the beer stated that the beer was primarily a medium for the message of "dogmatic notions of copyright and intellectual property that are dominating our culture", and admitted that the group had only limited experience in beer production and was not made up of beer gurus. The addition of the non-traditional beer ingredient Guaraná was also partly inspired politically by a previously 2003 initiated Superflex project, "Guaraná Power", which focused on the support of Brazilian guaraná farmers with Fair trade. After the first "Vores Øl" brewing of the open-source beer concept, Superflex continued to develop the concept under the name Free Beer. A new colorful, unusual Free Beer artwork should create associations with the "60's [artistic] liberation" and underline the freedom aspect of the concept. The later name Free Beer is a play on Richard Stallman's common remark that free software is "free as in speech, not free as in beer", who also suggested the creation of "Free software beer" instead of an "open source
