Produced by BrewDog -- the same people that brought you Tactical Nuclear Penguin -- Sunk Punk is an IPA made with lager yeasts, buckthorn berries, distilled sea salt, and
rum. It's actually brewed nearly 60ft below the surface; that's it getting sunk up above, in a specially designed tank with everything from pressurized gas release valves to a Jolly Roger, just in case someone tries to steal the treasure within. They've got a pretty awesome video explaining the whole thing, and don't worry -- it's got subtitles if you don't speak Scots.
