I'll have to look at the article, but if t-jack is drinking 'their IPA' I don't think we're all on the same page.
The original Narraganssett was a RI brewed lager much like Schlitz, Bud, Iron City, Ranier, Stroh's, etc. It's the beer Robert Shaw is drinking in the "Jaws" scene where he chugs it down and crushes the can while staring at Hooper. In response Richard Dryfeuss glugs down his herbal tea and then, while staring back at Shaw, slowly crushes his empty styrofoam cup.
I thought the original 'Gansett was long defunct - sounds like the name may have been resurrected....
