this is true, but since I didn't have a .56 KH to trade I ended up sending 2 KHs. Straight up, no extras agreed upon. 2 for 1.
Yeah, it was only made once, and the only place to try it now is City Beer Store, on-premise only for $60. I know that Bruery released a handful of extra bottles a few months ago, but it is definitely rare these days.
