So a friend and I were here yesterday evening and got butterbeers at the Hogshead and at first she told me it tasted funny. As I looked at the bartender, I noticed they were filling half of my drink from the bar-gun (presumably club-soda) and the other half with butterbeer from the barrel dispenser before adding the froth. I definitely don't remember normal cold butterbeer being a three-step process. Is this some kind of new, cheaper brew?
