A number of pubs have vowed to take Coopers beer off their taps after a political marketing stunt backfired disastrously on the South Australian brewer.

Coopers teamed up with their long-time donation recipients, the Bible Society Australia, to create a video on same-sex marriage called "Keeping It Light".

The family-owned and run brewer also released a commemorative light beer to celebrate 200 years of charitable work done by the Bible Society.

In the video, Liberals MPs Tim Wilson and Andrew Hastie debate same-sex marriage with the men agreeing to disagree in a "civil and respectful way".
