Brewdog microbrewery does not dick around when it comes to making manly beer. They’ve taken it upon themselves to create the “first commercially available, genuine sea-aged IPA in two centuries.” What that means is that they are going back to the roots of how IPAs were made which has a lot to do with colonial Britain. Let us explain.

IPA stands for Indian Pale Ale because they’d brew it in England, and then let the beer age in barrels while ships traveled from the seat of the throne to colonial Brittish colonies in East India. Because, honestly, we can’t have the troops without a frosty beer to end a march with. They’re not barbarians.

In order for the beer to survive this trip, it had to have a great deal of hops in the recipe to protect it from spoiling over time. This makes the beer particularly flavorful and high in alcohol—two things prized by any agent of the crown, to be sure.

Recently, they decided to hark back to this tradition by brewing some beer and then taking to the flippin’ sea. Why? Here’s what they say:

“Going beyond the realms of what would normally be deemed possible in order to deliver is what we’re all about at Brew Dog. We’re constantly pushing ourselves to come up with audacious, unusual and cool concepts and Atlantic IPA is definitely the most ambitious brew project we’ve accomplished to date."

Marketing speak or genuine innovation? Well, seeing as how they plunged one of their workers into the sea before the trip even started to save one of the barrels, we’re compelled to believe the authenticity of their venture. [Buy it]
