I have been making beer runs to Arkansas for the same reason, no headache and better taste for standard Miller products. 3.2 is pulled off before it has fully fermented and some of the hops are still raw. Try eating raw hops and see how they taste.
Making a trip to TX this weekend and will stock up before hitting the river on the way back.
The beer doesn't ferment while the wort is cooking. It ferments during the weeks it sits with the yeast in bottom of the lager tank. The hops added during cooking are just as raw or cooked at the start of the lager fermentation as they are the end of it.
The 3.2 beer may taste deficient, I agree, but too much hops sure as heck ain't the problem.
