Should almost certainly depend on the type of beer, the ingredients, and its manufacture. Some types of beer (specifically some types of bottle fermented) tend to lead towards leaving unfermented sugars in the bottle. Sugar can cause hangovers on its own, so combined with alcohol and fusel oils, could contribute extra towards a hangover beyond just the general dehydration. I had a friend of mine complaining once that Belgian-style beers tended to cause more powerful hangovers, and halfway through telling him it was all in his head, I was interrupted by a more experienced craft brewer who interjected that it may well not be. The science of it is pretty interesting. http://www.chemistryviews.org/details/ezine/1080019/Chemistry_of_a_Hangover__Alcohol_and_its_Consequences_Part_3.html http://www.chemistryviews.org/details/ezine/1080019/Chemistr...
