I'm sure the Canes didn't want to pay a premium for it, no doubt so that's probably a piece of it, but based on how it tastes, I still think it was aimed at trying to be palatable to the widest range of people, and when you do that, you get something very unremarkable and not quite craft style. From what I can tell, the largest % of beer drinkers at the Canes games are drinking bud light, by far. You make the "storm brew" be a hoppy IPA or a dark stout, virtually none of the bud light drinkers are going to even touch it. My buddy that I go to the games with (AD and Hurricure met him at the tailgate), drinks mich ultra and bud light. He'll go without a beer rather than drink any craft brew. Yet he tried a Storm Brew and his comment. "This is ok". He didn't prefer it over bud light, but he would at least drink it where there's no way he'd touch an IPA or stout, or even something as tame as a Fat Tire.
I think they were purposefully going for a low cost, non-descript beer, and that's what they got.
