I think I’m allergic to tannins. Or maybe I’m allergic to wine.
A customer told me a story about ending up in the hospital after sharing a single bottle of red wine with two other people, over a large meal. He became violently ill a couple of hours after leaving the restaurant. While in the ER he feared at first that he would die and then, as more of his insides keep surfacing, was afraid that he would not. This guy drinks moderate amounts of wine on a weekly basis and does not usually buy things from the bargain shelves. I don’t know exactly which wine he and his party consumed but I know the restaurant, the sommelier and the wines and none of them are badly made or have a lot of unnecessary chemical additives. This experience caused this wine drinker to decide that tannins are to blame for his violent adverse reactions. Now, stays away from bold, tannic reds which he loves but feels he can’t drink. What really went wrong?
Somewhat ironically, tannins usually don’t bother people. However, this term is common so we use it. The truth is that two other compounds found in wine are far more likely to cause you to feel badly: sulphite and histamine. If you can eat dried fruit, drink white wine or drink orange juice, you do not have a sulphite intolerance; there is far more sulphite in your container of OJ than in any of the bottles on my shelves. Histamine can be problematic, especially from those who suffer from asthma. It’s thought that people intolerant to wine cannot degrade histamine properly because they are deficient in diamine oxidase (the enzyme fulfilling this role). However, a recent study I saw showed no correlation between histamine content and wine intolerance. Red wines have 0.6 – 4.0 grams/litre of histamine and whites a lot less. So if your doctor says it’s ok, try taking an antihistamine before you drink red wine the next time and see what happens.
The offending wine might have been simply an ingredient – active or inactive – the cocktail that made our friend from above ill. Stress, dehydration, food, quatinty consumes and bugs hanging about in your system could also contribute to an adverse reaction. I also hear often that people are allergic to wine. That may be true, but genuine wine allergies are extremely rare (a true allergic reaction involves an immune response to an allergen, most commonly a protein). Sadly, there’s so little conclusive medical research about adverse wine reactions that there’s very little that can be done for those who have more or less random negative reactions to wine. Seems like the only thing we can be remotely certain of is this: most, if not all, unpleasant reactions to wines are food intolerances. There’s something to chew on.
