Part of our Asian Flush & Alcohol guide library.
Short answer: No single cause of red wine headaches has been proven. The leading suspects are histamine, which can be many times higher in red wine than in white, and quercetin, a plant compound found mostly in red wine that blocked the enzyme that clears acetaldehyde in a 2023 lab study. Alcohol itself, and how much you drink, also play a part. Sulfites are often blamed, but research mainly links them to asthma-type reactions rather than headaches. The same suspects can explain why red wine makes some people flushed, stuffy, sleepy or sick when other drinks do not.
One glass of red wine and your head is pounding, while white wine or a cocktail barely bothers you. You are not imagining it: red wine is the drink most often named in headache and wine-intolerance studies. Here is what researchers know, and do not yet know, about why red wine causes headaches, sleepiness, a stuffy nose and nausea, and what you can do about it.

What does a red wine headache feel like, and when does it start?
Researchers describe red wine headache as one that often starts 30 minutes to 3 hours after only one or two glasses, so it does not take heavy drinking (Devi et al., 2023). Headache experts recognize two types of alcohol-related headache: an immediate one that starts within 3 hours of drinking, and a delayed, hangover-type headache that starts 5 to 12 hours later. Both usually go away within 72 hours (Devi et al., 2023).
So a headache during dinner is more likely the immediate type, while waking up with one is the hangover type. For the morning-after kind, see how long a hangover lasts.
What causes red wine headaches? The main suspects
Many components of wine have been proposed, including biogenic amines such as histamine, sulfites, flavonoids and tannins, but no single one has been clearly shown to be the main trigger (Devi et al., 2023).
| Suspect | Why it is suspected | How strong the evidence is |
|---|---|---|
| Histamine | In one analysis, red wines had 60 to 3,800 micrograms of histamine per liter, compared with 3 to 120 in white wines (Wantke et al., 1994). | Moderate for people with histamine intolerance; small studies |
| Quercetin | Red wine has much more quercetin than white wine or other drinks. In the lab, a quercetin byproduct blocked ALDH2, the enzyme that clears acetaldehyde (Devi et al., 2023). | Early: lab study only, not yet tested in people |
| Alcohol and acetaldehyde | Alcohol is broken down into acetaldehyde, which can cause flushing, nausea and headache when it builds up (Devi et al., 2023). | Strong as a cause of alcohol headaches in general |
| Sulfites | Added to most wines as a preservative; listed on U.S. labels at 10 ppm or more (TTB). | Mainly linked to asthma-type reactions, not headaches (Vally & Misso, 2012) |
| Tannins and other phenolics | Red wine has about ten times more phenolic compounds than white wine (Devi et al., 2023). | Proposed, but high-phenolic foods have not been linked to headache (Devi et al., 2023) |
Histamine: why red wine can cause headaches in some people
Histamine is the strongest-studied suspect. In a red wine challenge, 28 people who reported wine intolerance and 10 people who did not each drank a small glass (125 mL, about 4 ounces) of red wine. 22 of the 28 had symptoms, and their blood histamine was higher 30 minutes later than in the people without symptoms. The symptoms included sneezing, flushing, headache, diarrhea, itchy skin and shortness of breath (Wantke et al., 1994).
The researchers linked this to histamine intolerance, where the body breaks down histamine more slowly because of low activity of an enzyme called diamine oxidase. Alcohol also slows this enzyme (Jarisch & Wantke, 1996). Since the highest red wines in that study had about 30 times more histamine than the highest white wines, by our calculation, people with this problem often react to red wine first (Wantke et al., 1994).
Quercetin: the newest theory, and how it links to Asian flush
In 2023, researchers at the University of California, Davis, proposed a new explanation. Red wine contains much higher levels of quercetin than white wine or other alcoholic drinks. In lab tests, a form of quercetin that circulates in the blood after drinking red wine blocked ALDH2, the main enzyme that clears acetaldehyde (Devi et al., 2023).
If that happens in the body, acetaldehyde would build up, which is the same thing that happens in people with the Asian flush gene, who often get flushing, headache, a fast heartbeat and nausea when they drink (Devi et al., 2023; Brooks et al., 2009). The authors were clear that this is a hypothesis and that it still needs to be tested in people (Devi et al., 2023). See why Asians get Asian flush and how long acetaldehyde stays in your body.
The amount of quercetin varies a lot between wines. It is higher in grapes grown with more sun, and in one comparison, ultra-premium Cabernet Sauvignon wines had about four times more flavonols than mass-market ones (Devi et al., 2023). So a pricier red is not necessarily easier on your head.
Are sulfites the cause of red wine headaches?
Probably not for most people. Sulfites are the most famous suspect because "Contains sulfites" appears on U.S. wine labels whenever they are present at 10 parts per million or more (TTB). But the research on sulfite sensitivity mostly involves people with asthma: it is reported in about 3% to 10% of people with asthma who ingest sulfite additives, with reactions ranging from hives and flushing to serious asthma attacks (Vally & Misso, 2012). Reviews of wine headaches list sulfites as one possible factor, not a proven cause (Devi et al., 2023; Panconesi, 2008).
If wine gives you wheezing or chest tightness, sulfites are worth discussing with a doctor. See alcohol intolerance vs alcohol allergy.
Why does red wine make me sick but not white wine?
Most likely because red wine carries more of the compounds suspected in reactions: about ten times more phenolics, much more quercetin (Devi et al., 2023), and usually much more histamine than white wine (Wantke et al., 1994). If one of these is your trigger, red wine will bother you more than white, even at the same amount of alcohol. If every kind of alcohol makes you flush or feel sick, the alcohol itself, or the way your body handles acetaldehyde, is the more likely cause (Brooks et al., 2009).
Why does red wine make me congested or sneeze?
A stuffy or runny nose after drinking is common. In a survey of more than 9,000 adults in Sweden, 3.4% reported nasal symptoms from alcohol. Of those, 83% named red wine as a trigger and 31% named white wine. A blocked nose was the most common symptom, followed by sneezing and a runny nose. These symptoms were about twice as common in women, and were more common in people with asthma or allergic rhinitis (Nihlén et al., 2005).
Histamine is one likely reason, since sneezing was among the symptoms in the red wine challenge study (Wantke et al., 1994).
Why does red wine make me sleepy?
Mostly because of the alcohol. In a controlled study, a moderate dose of alcohol (0.4 grams per kilogram of body weight) increased feelings of sedation about 90 minutes after drinking (Holdstock & de Wit, 1998). For a 150-pound person, that is about 27 grams of alcohol, or about two standard drinks, by our calculation. A standard drink is a 5-ounce glass of wine at 12% alcohol (NIAAA), and many restaurant pours are bigger than that.
Alcohol helps you fall asleep faster but disrupts sleep in the second half of the night (Ebrahim et al., 2013), which is why you can feel tired the next day even after a full night in bed. See is alcohol a stimulant or a depressant.
Why does red wine make me hot, flushed or sick to my stomach?
Flushing, feeling hot and nausea can come from two directions. Histamine reactions to red wine can cause flushing and diarrhea (Wantke et al., 1994), and acetaldehyde buildup causes flushing, nausea and a fast heartbeat, especially in people with the Asian flush gene (Brooks et al., 2009). If your face turns red after any alcoholic drink, not just red wine, see is Asian flush dangerous.
Red wine and migraine
If you get migraines, alcohol can be a trigger, but less often than many people think. In studies that asked people afterward, about a third of migraine patients said alcohol triggered an attack at least occasionally, but only about 10% said it did so often. Studies that tracked people going forward found alcohol to be a less important trigger, and while red wine is often named as the main culprit, other studies point to white wine or other drinks (Panconesi, 2008).
Keeping a headache diary that notes what and how much you drank is the most reliable way to find your own pattern.
How to avoid a red wine headache
- Drink less, and more slowly. Red wine headaches can start after one or two glasses (Devi et al., 2023), so pour size matters. A standard glass is 5 ounces (NIAAA).
- Keep notes. Write down the wine, how much you had and how you felt. Reacting to red wine only points to something in the wine; reacting to all alcohol points to the alcohol itself.
- Try a different wine, or skip it. White wines usually have less histamine and quercetin (Wantke et al., 1994; Devi et al., 2023). A non-alcoholic drink avoids the alcohol altogether. See easy mocktail recipes.
- Be wary of quick fixes. We did not find published human trials of wine drops or filters for red wine headaches. Antihistamines may hide some symptoms but do not lower acetaldehyde. See Asian flush pills, Pepcid and patches.
- Remember that only time ends a hangover. There is no cure for a hangover other than time (NIAAA).
When to see a doctor
- You get a headache, rash, stuffy nose or stomach upset after small amounts of wine most times you drink.
- Wine gives you wheezing, chest tightness or shortness of breath, especially if you have asthma (Vally & Misso, 2012).
- You have symptoms of anaphylaxis, such as trouble breathing, swelling of the face or throat, or widespread hives. This is an emergency: call 911 (MedlinePlus).
- Your headache is sudden and explosive, the worst you have ever had, or comes with slurred speech, vision changes, weakness, confusion or loss of balance. Get emergency care (MedlinePlus).
Common myths (quick reality check)
Myth: Sulfites are the reason red wine gives you a headache. Reality: Sulfite sensitivity is mainly linked to asthma-type reactions. Histamine and quercetin are stronger suspects for headaches, though none is proven.
Myth: Only heavy drinking causes red wine headaches. Reality: Researchers describe red wine headaches starting after only one or two glasses.
Myth: Expensive red wine won't give you a headache. Reality: In one comparison, ultra-premium Cabernet Sauvignon wines had about four times more flavonols, including quercetin, than mass-market ones.
Frequently asked questions (FAQ)
Why does red wine give me a headache?
No single cause is proven. Histamine and quercetin are the leading suspects, along with alcohol itself. Red wine has much more of both than white wine.
Why does red wine give me a headache but not white wine?
Red wine has about ten times more phenolics, much more quercetin and usually much more histamine than white wine, so people sensitive to these react to red first.
Do sulfites in wine cause headaches?
Probably not for most people. Sulfite sensitivity mostly shows up as asthma-type reactions, reported in about 3% to 10% of people with asthma.
Why does red wine make me congested?
Nasal symptoms from alcohol affected 3.4% of adults in a large survey, and 83% of them named red wine. Histamine is one likely reason.
Why does red wine make me sleepy?
Alcohol is sedating: about two standard drinks increased sedation 90 minutes later in a controlled study. It also disrupts the second half of your sleep.
How long does a red wine headache last?
An immediate alcohol headache starts within 3 hours and a hangover headache within 5 to 12 hours. Both usually go away within 72 hours.
Is a red wine headache related to Asian flush?
Possibly. A 2023 lab study found that a quercetin byproduct blocks ALDH2, the same enzyme that works poorly in people with Asian flush. It has not yet been tested in people.
