Wine is one of the world’s most loved drinks—but for some people, even one glass can trigger strange symptoms. Maybe you feel flushed, get a pounding headache, or your stomach turns. Many mistake these symptoms for a hangover, but they may signal a wine allergy. You could be dealing with a wine allergy, a wine intolerance, or a reaction to something in the drink itself.
In this guide, we’ll break down the difference between wine allergy and intolerance, list common symptoms, and help you understand what’s really behind your reaction.

What Is a Wine Allergy?
A wine allergy occurs when your immune system overreacts to certain substances in wine. This overreaction, known as an immune system response, causes the body to treat a harmless substance—such as a grape protein, sulfite, or histamine—as if it were a harmful invader.
The body then releases chemicals like histamine, which may lead to side effects such as:
- Hives or rash
- Facial flushing
- Swelling of the lips, throat, or tongue
- Nasal congestion or runny nose
- Difficulty breathing
- Digestive upset
In rare cases, a wine allergy can lead to anaphylaxis, a severe and life-threatening condition that requires emergency medical treatment.
Wine Intolerance vs Allergy: What’s the Difference?
Although wine intolerance and wine allergies may cause similar symptoms, they are very different conditions.
Wine allergy is an immune-related condition that may cause serious reactions, including breathing problems, swelling, and hives.
Wine intolerance, on the other hand, is not immune-related. It happens when your body struggles to break down certain substances in wine, such as sulfites, tannins, or aldehyde dehydrogenases (enzymes that help break down alcohol).
Symptoms of alcohol intolerance or wine intolerance include:
- Facial flushing
- Nasal congestion
- Runny nose
- Headaches
- Digestive discomfort like bloating or nausea
People with alcohol intolerance often react to small amounts of wine or other alcoholic drinks, but their symptoms tend to be less severe than those of a true allergy.
Common Wine Allergy Symptoms
So, what are the most common symptoms of wine allergy? These may appear within minutes of drinking wine and vary in severity. Typical signs include:
- Itchy skin, rash, or hives
- Swelling of the lips, mouth, or throat
- Tightness in the chest or trouble breathing
- Nasal congestion or runny nose
- Facial flushing
- Stomach cramps or vomiting in some cases
If these adverse reactions are familiar, you may be dealing with more than just a bad hangover. Speak with a healthcare provider to rule out underlying health conditions and get an accurate diagnosis.
What Causes Wine Allergies?
There are several wine allergy causes and potential allergens in wine that can trigger allergic reactions in sensitive individuals. These triggers vary from natural compounds in grapes to additives used during production. Common examples include:
- Histamines – Produced during fermentation, histamines are found in higher levels in red wine and may cause runny nose, facial flushing, headaches, or skin reactions.
- Sulfites – These preservatives are commonly used in wine and can lead to asthma-like side effects or adverse reactions in those who are sensitive.
- Tannins – Present in grape skins, seeds, and stems, tannins are natural compounds that can cause headaches or nausea in some individuals.
- Grapes – In rare cases, a person may have a food allergy to grapes themselves, leading to allergic symptoms after drinking wine.
- Alcohol – Some people react to alcoholic beverages due to an alcohol intolerance or allergy to ethanol or other ingredients used in production.
- Other health conditions – Conditions like asthma, nasal congestion, or chronic rhinitis may increase the risk of reactions to wine or worsen existing symptoms.
Understanding these wine allergy causes and potential triggers can help you avoid specific types of wine or alcoholic drinks that are more likely to cause discomfort.
Ingredients in Wine That Trigger Reactions
In addition to sulfites and tannins, wine contains other additives that can trigger allergic or intolerance reactions in some individuals. These include:
- Yeasts used in fermentation
- Fining agents like egg whites, casein (from milk), or isinglass (derived from fish)
- Artificial colorants and stabilizers used in mass-produced wines
While these substances are typically present in small amounts, they can still cause problems for people with food allergies. Choosing organic, vegan, or unfiltered wines may help reduce the risk of exposure to these hidden allergens.
Understanding Alcohol Allergy Symptoms
A wine allergy can be confused with a general alcohol allergy, but there are some key differences.
Alcohol allergy symptoms typically include:
- Red or itchy skin
- Hives
- Facial swelling
- Difficulty breathing
- Low blood pressure in severe cases
In contrast, alcohol intolerance may only cause milder symptoms such as:
- Facial flushing
- Headaches
- Nasal congestion
- Upset stomach
Keeping a symptom diary and getting tested can help you determine the root cause.

How to Avoid Wine Allergy Symptoms?
If you think you have a wine allergy or intolerance, these steps can help:
- Avoid alcohol or select drinks less likely to cause a reaction.
- Try white wine or rosé, which usually contain fewer histamines and sulfites than red wine.
- Look for labels marked “low in sulfites” or “organic.”
- Experiment with different grape types and wine brands to identify triggers.
- Limit consumption to small amounts to assess tolerance.
By understanding your body’s reaction, you can make safer choices when you drink alcohol.
Allergy Tests and Diagnosis
To confirm whether you have a wine allergy, consult a healthcare professional who may recommend allergy tests. These may include:
- Skin prick tests to check for allergies to grapes, sulfites, or other wine ingredients.
- Blood tests to assess your immune system’s response to specific compounds.
- Elimination testing, where certain ingredients are removed from your diet under supervision.
These tests can help pinpoint the exact cause of your reactions to wine and rule out other health conditions like asthma or food sensitivities.
Can You Still Drink Alcohol?
If you’re diagnosed with a wine allergy, your doctor will likely advise you to avoid alcohol altogether or steer clear of specific types of wine. That said, some people with mild reactions may still be able to enjoy alcoholic beverages that don’t contain their specific trigger.
For instance:
- Those with a sulfite sensitivity might tolerate white wine or organic wine better than red.
- Individuals with histamine intolerance may benefit from low-histamine wine brands.
- People with alcohol intolerance may need to reduce consumption or switch to alternatives like cider or gluten-free beer.
When in doubt, always consult your doctor before making changes to your drinking habits.
Seeking Treatment for Wine Allergies
If your reactions to wine are severe, don’t ignore them. Seek medical attention right away. Treatment may include:
- Antihistamines to manage mild symptoms like itching or runny nose
- Prescription medications or an epinephrine auto-injector for more serious side effects
- Advice on how to adjust your lifestyle to reduce risk and discomfort
Taking action early can prevent complications and help you enjoy life more comfortably.
Wine Allergy Treatment Near Me: What Are Your Options?
If you regularly experience symptoms after drinking wine—like hives, swelling, or difficulty breathing—it’s important to seek medical guidance. A healthcare provider can help you determine whether you’re dealing with a wine allergy, wine intolerance, or another condition.
Treatment options typically include:
- Allergy testing – Skin prick or blood tests to identify specific triggers such as sulfites, histamines, or grape proteins.
- Avoidance strategies – Learning which types of wine or alcoholic beverages are safer based on your test results.
- Symptom management – Antihistamines for mild symptoms or emergency medications like epinephrine for severe reactions.
- Referral to specialists – Allergists or immunologists can offer tailored advice and long-term care plans.
If your symptoms are frequent or severe, consider searching for an allergist or immunologist near you. Early diagnosis and the right treatment can help you avoid complications and enjoy a better quality of life.
