Good article and a good night.
As I said to TBN, I wish I'd remembered to ask people to put down their favourite and least favourite at the same time as the names of the beers. It would have been interesting data. As far as I can remember, the three people at my sitting all picked the same favourite and least favourite beer (ESB & Abbot respecively), whatever they the thought the brand was.
My idea for a different sort of tasting was to line up a bunch of beers, not necessarily of the same or even similar styles and simply get people to rate them, without knowing what brand they are.
It would have the same predjudice busting effect without the possibility of me scoring 0 again.
