I was adding up the weeks and it really doesn't seem terribly fast. It's not uncommon for a beer, especially at the commercial level, to ferment out in 10 days. It then takes them another 4 weeks or so before they bottle it. It's actually probably a little on the slow side. My guess is they aren't using a filter so they are chilling the beer (or lagering) for an extended time period to help drop the hops, yeast and proteins out of suspension. But it's cool that they shared.
