Brews You Can Use IV

I found this interesting observation at Video meliora:

One of the biggest tragedies in being over forty is that Guinness, even in small doses, now gives me blinding headaches. Red wine too. "Sulfites" they say, but me I think it is devilry from the sixth circle of Hell, perpetrated on me by my nemesis Asmoday. Can it be coincidence that "sulfite" sounds like the material that paves that particular street of perdition?
