Wine, Bad?

So last night's glass, ok, glasses of wine surprisingly did not cause quite as much of a stir this time.

Last week when I had a few glasses, my allergies basically went out of control. Fortunately my tummy remained in tact, but my nose ran, my head clogged. For about 24 hours it basically felt like a moderate cold. My throat is a teensy bit sore and I've a bit of a headache, but nothing so severe. And seeing as how it is now 24 hrs. later, I may very well have ingested something else I shouldn't have.

As for the wine, I did probably only consume 1/2 to 2/3 of the amount of last week, but still, I find myself surprised. How is it that last week my almost immediate and lasting reaction was quite intense, and this week, barely noticeable. Perhaps a bit of congestion occured, but nothing significant.

I've been researching for some time tonight. There are quite a few possibilities: sulfites, yeast and tannins. I do think that something here causes an upset, because my skin even seems to have produced a few breakouts since last night.
