Not entirely fair.
I can't say Belgian ales suck, except to me. But I think they suck. And I don't understand why there is so much love for them. I have tried them over and over again, and it's like the definition of insanity: doing the same thing over and over again and expecting different results. Definitely, Chimay tastes different from Duvel, and Duvel tastes different from Ommegang. Doesn't mean I like them.
And yet, here are at least two beers (and add to this list the Trip IV from Mulleady's) with distinctly Belgian ale flavors without the Belgian sourness. I know that Guinness tastes different in the US than it does in Ireland. I know that kegged Arrogant Bastard has a vastly better flavor than bottled Arrogant Bastard. But how is it that Belgian ales deteriorate this much?
