I was waiting for this thread to appear.
Nothing available on way back from PHX in J last night, nothing in T5 but did manage to get a couple on the LHR-NCL hop back - no pun intended
As a someone who travels the world to appreciate beer I thought this was an excellent modern style Pale Ale, I hope it becomes a regular offering.
It's certainly not sour, try a real spontaneously fermented beer from a brewery like Cantillon or BrewDog's very own excellent OverWorks brewery for that flavour profile.
For the record my favourite airline beer is Voodoo Ranger, sometimes served on AA.
