Cue the jokes, but Greene King are feeding their beer to cattle. Actually to be true they are sending out of date beer to be recycled for cattle feed. There are all sorts of green reasons why this is a nice idea which are mentioned in the BBC report, so hats off to GK. I am not aware what the normal practice is for unusable beer, but this seems as good a venture as there is out there.
I hope the beer doesn't come to the cows near me though. I really couldn't bear the smell of Greene King IPA cow farts.
