I'd say they're both a 3, but that's considering Sam Adams is basically the Yankees of 'microbrews', when they hit you with a big beer, I expect to be wowed. I liked their latitude 48 IPA well enough, but these were..meh.
Don't get me wrong; the IPA sampler left me satisfied, just nothing more.
A DIPA should be like what I expect fistfighting with Natalie Portman is like; still a punch in the face, with nothing held back, with more wallop than you're ready for, but still a punch in the face youd take a thousand times more.
The Dark Depths descriptiTion is much the same. You're gonna cross a big porter with an IPA? Why content yourself with a single? Go for the homerun.
