I think we should wait for a bigger crowd for that. Boak and Bailey were asking me[/url:1aaokop8] if Porterhouse Alt is better than their Alt-substitute: ice-cold London Pride with a big head. We could try answering that one.
Of course you'll need a Real Alt (horribly close to real ale, I apologise) as a control, unless you just want it to be relative. Does the PH have alts other than Gaffel?
