I've got to agree with Whorst on this one....... I did a similar beer a while back, and it tasted very lagerish indeed - it even fooled some of my lager drinking mates (although the colour was a bit too dark, they still accepted it was "Czech style" lager without question)
Of course, it wouldn't have fooled a seasoned ale drinker, or any kind of homebrewer, but them's the breaks!
