It’s tough to make out, but the green figure on the label (Hoptimus Prime, presumably, striking a heroic pose) is muscular, roughly humanoid, and appropriately, made entirely out of hops.

As one might expect, the beer has quite a bit of hoppy flavor to it and, as Autobot Commander Optimus Prime would say, is “made of sterner stuff.”
