Colwyn this purity of the lager notion -free range or otherwise - has to be challenged. I see myself in this respect as a latter day Frank D Ripper from Dr Strangelove, and in order to prevent harm to my 'precious bodily fluids' I have fore sworn myself off the the Teutonic brew, that seeks to dominate the world for the master race more effectively and efficiently than the Euro. And so only drink the finest of English beers, and so maintain a 'purity of essence'.
