Short answer: red wine headaches usually don't come from one single cause. Researchers point to a handful of likely culprits: histamines (much higher in red wine than white), sulfites (which affect a small share of people), a grape compound called quercetin, tannins, and the alcohol itself. Which one bothers you can differ from person to person, which is why the same glass can give one friend a headache and leave another feeling fine.
Is it the histamines?
Histamine forms naturally during fermentation, and red wine tends to carry far more of it than white. An Austrian study published in Allergy Proceedings measured roughly 60 to 3,800 micrograms per liter in red wines, compared with about 3 to 120 in white wines.
In the same study, most participants with a history of wine intolerance developed symptoms and higher blood histamine after a small glass of red wine, and taking an antihistamine beforehand prevented symptoms for most of them. The researchers suggested these people may not break histamine down efficiently, possibly because of low levels of an enzyme called diamine oxidase (DAO).
Signs people commonly link to histamine include headache, flushing, a stuffy or runny nose, and itching.
Is it the sulfites?
Sulfites help keep wine fresh, and a small amount forms naturally during fermentation. The U.S. Food and Drug Administration estimates that about 1 in 100 people is sulfite-sensitive, and that about 5 percent of people with asthma are at risk of a reaction. In the U.S., foods and wines with 10 parts per million or more of sulfites must disclose them, which is why most bottles say "Contains sulfites."
For most people, sulfites are probably not the main cause of a wine headache. Dried fruit, for example, typically contains far more sulfites than a glass of wine. But people who are sensitive can react, sometimes with breathing or skin symptoms rather than a headache.
What about quercetin?
In 2023, researchers at UC Davis published a study in Scientific Reports pointing to quercetin, an antioxidant that grapes produce in response to sunlight. Their lab work suggests that as the body processes quercetin, it can slow the breakdown of alcohol, letting a compound called acetaldehyde build up. Acetaldehyde is linked to flushing, headache and nausea.
Red wines made from sun-exposed grapes can contain several times more quercetin than others. This is still a hypothesis: the researchers' next step is a clinical trial in people who get red wine headaches.
Tannins and the alcohol itself
Tannins come from grape skins, seeds and oak barrels, and red wines have much more of them than whites. Some people point to tannins as a trigger, but research hasn't confirmed them as a cause.
The alcohol matters too. Alcohol can dehydrate you and trigger a headache on its own, especially if you're drinking on an empty stomach or drinking quickly.
How to lower your chances of a red wine headache
- Drink water between glasses, and eat while you drink.
- Pace yourself. Slower drinking gives your body more time to process alcohol.
- Try lighter wines. White and lighter-bodied wines tend to be lower in histamine and tannins.
- Keep notes. Grape, region and winemaking style all change histamine and quercetin levels, so tracking which wines bother you can reveal a pattern.
- Try a wine filter if you suspect histamines or sulfites. Wine Balanced is a drop-in sachet that helps reduce sulfites and histamines in your glass in 1 to 3 minutes, with no wand or device, and it doesn't change the taste. It doesn't remove alcohol, quercetin or tannins, so the tips above still apply. Note: Wine Balanced contains chitosan, which is derived from shellfish, so don't use it if you have a shellfish allergy.
- See a doctor if headaches are frequent or severe, or if you have asthma or a diagnosed sulfite allergy.

Quick answers
Why does red wine give me a headache but white wine doesn't?
Red wine is typically much higher in histamine, tannins and quercetin than white wine, because red wine is fermented with the grape skins. If any of those is your trigger, red wine will bother you more.
Are sulfites the cause of red wine headaches?
For most people, probably not the main cause. About 1 in 100 people is sulfite-sensitive, according to the FDA. Histamine and quercetin are more likely suspects for many red wine headaches.
Can I take something to prevent a red wine headache?
In one study, an antihistamine taken before drinking prevented symptoms for most histamine-sensitive participants. Talk to your doctor or pharmacist before taking any medication with alcohol.
Does a wine filter help with red wine headaches?
A wine filter like Wine Balanced helps reduce sulfites and histamines, two common suspects. If one of those is your trigger, a filter may help. It won't change the alcohol content.
