There are two big breweries based in Boston proper; Samuel Adams and Harpoon. The Sam Adam brewery is only for small batches and experimental brews, while the Harpoon brewery is in full production.
I’ve taken tours of both facilities and while I was initially a bigger fan of the Sam Adams tour, I’ve started to lean more toward Harpoon. Their tasting portion is much more extensive; you have fifteen minutes to try any of the 7 or so beers they have on tap, as opposed to the three beers that Sam Adams gives you.
This is how I first came across the Leviathan Imperial IPA, in room surrounded by Harpoon merchandise and the Harpoon staff after imbibing six or seven tiny glasses of beer. I loved it.
But I decided to subject it to a more objective judgement. I bought a four-pack of them and poured them into my Harpoon-brand tulip glass. It smells intensely like an IPA; that hoppy, sweet smell that you either love or hate. The first sip and your taste buds are taking a brutal bitter beating. The Leviathan Imperial IPA is one of the more complex and well-rounded IPAs I’ve ever had. A lot of IPAs can leave you gagging on that signature bitterness long after you’ve finished the beer.
This one cuts it short, most likely through wizard magic, and the aftertaste is surprisingly minimal considering the hearty strength of the initial flavor. Out of the many IPA’s I’ve had over the last few years, this is one of the best, even though I still can’t claim to be an expert. It has a color that would put an amber ale to shame. Its flavor is complex and layered without being overpowering. And it packs a punch with the alcohol.
In short, if you can get it, you should.
I give it Two Bakers Chocolates and One Cup of My Coffee.

The best parts about your beer reviews is the awards you give them.
Too bad its a sea monster, I’ll have to settle for SA in OK. Sam will stay my favorite until the monster makes it here.
