Why Some People Get Headaches from Wine (and What Actually Causes It)
You’ve probably heard this before:
“I can drink vodka all night, but one glass of wine gives me a headache.”
It’s common. And frustrating.
Wine gets blamed a lot, especially red wine, but the real reasons are more nuanced than most people think. Some are biological. Some are chemical. Some are just… how you’re drinking.
This guide breaks down what’s actually happening in your body, in a way that makes sense without needing a chemistry degree.

First: Not All “Wine Headaches” Are the Same
Before we get into causes, we need to separate two very different things:
1. Immediate Headache (within minutes to an hour)
This is the one people usually mean.
You take a few sips, and your head starts to feel tight or pressure builds quickly.
2. Delayed Headache (next morning or later)
This is more of a classic hangover symptom.
Different causes. Different solutions.
This post focuses mostly on the immediate type, because that’s where wine specifically gets blamed.
The Biggest Myth: “It’s the Sulfites”
Let’s just clear this up first.
Sulfites are almost never the reason you’re getting a headache.
Sulfites are added to wine to protect it from oxidation and spoilage. They’re also naturally produced during fermentation.
Here’s the key point:
Dried fruit often has way more sulfites than wine
If sulfites caused headaches, far more people would react to foods like apricots or raisins
The real issue with sulfites is that only a small percentage of people are actually sensitive to them, most often those with asthma.
And when that happens, it typically affects breathing, not headaches.
So if you’re blaming sulfites for a headache, they’re probably not the cause.
What Actually Causes Wine Headaches
There isn’t just one answer. It’s usually a combination of factors.
1. Histamines
Histamines are one of the most common culprits.
They’re naturally present in wine, especially red wine, because of how it’s made.
What histamines do
Histamines can:
dilate blood vessels
trigger inflammation responses
contribute to headache symptoms in sensitive people
If you’ve ever had seasonal allergies, you already know how your body reacts to histamines.
Why red wine has more
Red wine spends more time in contact with grape skins during fermentation.
That matters because histamines are found in the skins, and the longer that contact lasts, the more of those compounds end up in the wine.
2. Tannins
Tannins are another big factor, especially for red wine.
They’re the compounds that give red wine its structure and that slight drying feeling on your gums.
What tannins do in your body
Tannins can stimulate the release of serotonin.
For some people, changes in serotonin levels can trigger headaches.
Why this matters
Not everyone reacts to tannins.
But if you consistently get headaches from:
Cabernet Sauvignon
Syrah
Nebbiolo
…and not from white wine, tannins are a strong suspect.
3. Alcohol Itself
This one gets overlooked because it’s less “interesting,” but it’s important.
Alcohol is a:
vasodilator (it widens blood vessels)
mild diuretic (it dehydrates you)
Both of those can contribute to headaches.
Why wine might hit differently
Wine is usually consumed more slowly and with food, but:
higher alcohol wines (15%+) can hit harder
if you’re slightly dehydrated already, effects amplify quickly
4. Congeners and Byproducts
Congeners are compounds produced during fermentation and aging.
They contribute to:
flavor
aroma
complexity
…but also, in some people, headaches.
These include:
aldehydes
esters
higher alcohols
Translation into real life
More complex wines can sometimes trigger stronger reactions in sensitive individuals
This doesn’t mean “better wine = worse headache”
It just means your body may react differently depending on composition.
5. Sugar (and Perceived Sweetness)
Residual sugar plays a smaller role, but it matters in certain situations.
Wines with noticeable sweetness can:
spike blood sugar
lead to a faster drop afterward
That swing can contribute to headaches for some people.
Why Red Wine Gets Blamed More Often
Red wine tends to have:
higher histamines
higher tannins
more complex phenolic compounds
So it’s not that red wine is “worse”
It’s just more likely to combine multiple triggers in one glass.
Other Factors That Matter More Than You Think
This is where most people underestimate things.
Dehydration
If you’re even slightly dehydrated before drinking wine, your chances of a headache go up fast.
Drinking Speed
Two glasses in 20 minutes hits very differently than two glasses over an hour with food.
Food Pairing
Drinking wine without food:
increases alcohol absorption rate
amplifies effects
Sleep and Stress
If you’re already:
tired
stressed
run down
Your body is more reactive.
Wine just becomes the thing you blame.
How to Reduce Your Chances of a Wine Headache
This is the part people actually care about.
1. Pay Attention to Wine Style
If you suspect tannins or histamines:
Try:
Pinot Noir (lighter tannin)
Gamay
White wines
Avoid (initially):
big Cabernet Sauvignon
heavily oaked reds
high alcohol wines
2. Hydrate Before and During
Simple, but effective.
drink water before wine
alternate water between glasses
3. Eat First
Food slows alcohol absorption and stabilizes your system.
Even something small makes a difference.
4. Slow Down
Give your body time to process.
This alone solves a surprising number of “wine headaches.”
5. Track Patterns
This is the most useful long-term strategy.
Notice:
which wines trigger headaches
which don’t
how much you had
what you ate
Within a few weeks, patterns usually become obvious.
FAQ
Why do I get headaches from red wine but not white?
Red wine has more histamines and tannins, both of which can trigger headaches in sensitive individuals.
Are cheaper wines more likely to cause headaches?
Not necessarily.
Price doesn’t directly correlate with headache risk.
However, very high alcohol or overly sweet wines can increase the likelihood depending on your sensitivity.
Do wine headache drops or filters work?
Some products claim to reduce histamines or sulfites.
They may help certain individuals, but they’re not a universal fix.
Understanding your personal triggers is more reliable.
Can organic or “natural” wines prevent headaches?
Not automatically.
They may have lower added sulfites, but that’s rarely the main issue.
Histamines, tannins, and alcohol are still present.

Final Thoughts
Wine headaches aren’t random.
They’re usually your body reacting to a combination of:
histamines
tannins
alcohol
and how you’re drinking
Once you understand that, it gets a lot easier to adjust.
For most people, it’s not about avoiding wine entirely.
It’s about figuring out which wines work for you and how to drink them in a way your body agrees with.
