For the record - the beer poured was an absolutely horrible home brew that is used exclusively as a prop beer. I was going for a slightly sloppy pour to have the head spill over the top a little (which it did).
I knew one day someone would call me out on that pour! Cheers!
It was at the Big Beers and Barleywines Festival. They had a bunch of other amazing beers - KBS, Blushing Monk, BORIS Royale, BA Naked Evil, '07 Stone IRS, etc... it was epic.
