Those of you who regularly suffer headaches from drinking a particular wine should read this month's Food and Wine magazine. An article explaining the likely causes of wine-aches is the most comprehensive and understandable one I've read on the subject.
In short, it's not the sulphites that for years have been inaccurately charged as the cause. Instead, scientific evidence points to naturally occurring compounds found in most wines -- phenolic flavonoids and biogenic amines. Flavonoids bring out the wine's color and flavor; they are found in the skins, stems and seeds of red wines. Biogenic amines appear during the fermentation process and are associated with histamine and tyramine compounds found most often in red wine. For that reason, most headache suffers say their problems occur after drinking red wines.
This working theory was confirmed in a relatively small study conducted by Argentine doctors who gave 28 people two wines to drink during a trial period: a cabernet sauvignon from Bordeaux and a cabernet sauvignon from South America. Sixty percent of the Bordeaux drinkers reported headaches; only 40 percent of the South American wine drinkers reported the same.
The explanation? Bordeaux producers extract the most tannin and phenolic flavonoids from their wines to give them longevity, color and depth of fruit. South American producers aren't looking for their wines to be aged and instead make them drinkable on release. The price comparison between the two wines confirms the difference in effort.
Although I know of some people who swear that only white wine gives them headaches, most of the people I know associate headaches with red wines. My wife, for instance, gets regular headaches after drinking even small amounts of Cline Cellars zinfandel -- every time. Alas, the wine is one of a handful that has given me a headache. These wines are fruit-forward, dense and dark in color. Is the producer extracting the most tannin and phenolic flavenoids it can?
So if you insist red wine, particularly those with forward flavors and tannin, gives you headaches, it's not all in your head.
