Can You Develop a Sensitivity to Wine? Understanding the Causes and Symptoms

Approximately 10% of the population experiences some form of hypersensitivity reaction to alcoholic beverages, particularly wine. The answer is yes, you can develop a sensitivity to wine over time, even after years of enjoying it without issue.

Quick Summary

Developing a sensitivity to wine is possible later in life due to biological changes or increased exposure to certain compounds. Reactions differ between true allergies and intolerances, with triggers including histamines, sulfites, and tannins.

Key Points

• Acquired Sensitivity: You can develop a sensitivity or intolerance to wine over time, even if you were previously unaffected.

• Allergy vs. Intolerance: A wine allergy is a rare immune response, while a wine intolerance is a more common digestive or metabolic issue.

• Common Triggers: Histamines (more common in reds), sulfites (preservatives), and tannins (in grape skins and barrels) are frequent culprits.

• Late-Onset Causes: Changes in body chemistry, reduced enzyme function with age, cumulative exposure, or genetic factors can trigger a new sensitivity.

• Symptom Management: Hydration, antihistamines, trigger avoidance, and trying different varietals can help manage common reactions like headaches, flushing, and digestive upset.

• When to See a Doctor: For severe symptoms or concerns about a true allergy, seeking professional medical diagnosis is essential.

Understanding Wine Allergies vs. Intolerances

It is critical to distinguish between a true wine allergy and a wine intolerance, as they involve different bodily systems and can manifest with varying severity. A true allergy is a rare, immune system-mediated response to a protein in the wine, where the body perceives the substance as a threat. Symptoms can appear quickly, from minutes to an hour after consumption, and in rare, severe cases can lead to anaphylaxis. An intolerance, on the other hand, is much more common and does not involve the immune system. It is a digestive issue, often resulting from the body's inability to efficiently process a particular compound. Intolerance symptoms can be delayed, sometimes appearing hours later, and are generally less severe than allergic reactions.

The Culprits: Common Wine Components That Cause Reactions

Several compounds found naturally or added during the winemaking process can trigger sensitivities. A person may be reactive to one, or a combination, of these elements.

• Histamine: Found in higher concentrations in red wines due to the fermentation process, histamines can cause headaches, flushing, skin rashes, and nasal congestion, especially in those with a histamine intolerance or a histamine-degrading enzyme (Diamine Oxidase) deficiency.
• Sulfites: These compounds are added as preservatives and are naturally present in wine. While a true sulfite allergy is rare, sensitivity can cause asthma-like symptoms, wheezing, and skin rashes, particularly in asthmatics. Contrary to popular belief, white and sweeter wines often contain higher sulfite levels than reds.
• Tannins: These bitter, astringent compounds found in the skins and seeds of grapes and oak barrels are more prominent in red wine. For sensitive individuals, tannins can cause headaches, migraines, and stomach pain. This is because tannins are polyphenols that can interfere with enzymes involved in detoxifying certain compounds.
• Proteins and Fining Agents: Winemakers sometimes use fining agents derived from animal products like egg whites (ovalbumin), dairy (casein), and fish bladders (isinglass) to clarify the wine. While typically removed via filtration, trace amounts may remain and trigger a reaction in someone with a severe food allergy. Vegan wines avoid animal-based fining agents, but could use other plant-based alternatives.
• Yeast and Mold: The yeasts used in fermentation, and even molds that contaminate grapes or corks, can be potential allergens, though reactions are relatively uncommon.

Why Sensitivity Can Develop Later in Life

Many people are surprised to suddenly find themselves reacting negatively to wine they once enjoyed without problems. The development of a sensitivity is often not an instant event but a cumulative process related to several factors:

• Changes in Enzyme Function: As we age, our bodies change. The efficiency of enzymes like Diamine Oxidase (DAO), which breaks down histamine, can decrease. A decline in DAO function means the body is less able to handle the histamine load from red wine, leading to new or more pronounced symptoms.
• Cumulative Exposure: Consistent exposure to an allergen or irritant can lead to the immune system eventually mounting a response. For some, years of enjoying wine without issue can prime the body for a sudden reaction, especially to minor allergens or compounds.
• Genetic Predisposition: Some people, particularly those of East Asian descent, have a genetic variation that affects the aldehyde dehydrogenase 2 (ALDH2) enzyme, which is crucial for metabolizing alcohol. This can lead to the accumulation of toxic acetaldehyde and cause severe flushing and other intolerance symptoms.
• Other Sensitivities: A pre-existing sensitivity, such as rhinitis or asthma, can be exacerbated by alcohol, triggering a hypersensitive reaction. Alcohol increases the permeability of the gut and blood vessels, potentially allowing more reactive compounds to enter the bloodstream and trigger symptoms.

Strategies for Managing Wine Sensitivity

Managing a wine sensitivity often involves a process of elimination to identify the specific trigger. Here are some actionable steps:

• Keep a Journal: For two to six weeks, meticulously track what you drink and eat, noting the type of wine (red, white, sparkling), the brand, and the timing and nature of any symptoms. This helps identify patterns.
• Try Different Varietals: Experiment with different types of wines. If red wines cause issues, try a crisp white. If white wines are the problem, particularly for asthmatics, it may be a sulfite issue.
• Choose Lower-Intervention Wines: Consider wines with lower levels of additives. Some winemakers produce wines with lower added sulfites. If allergic to a fining agent, choosing a vegan wine can help.
• Stay Hydrated: Dehydration can worsen headaches caused by wine. Drinking water alongside wine can help mitigate this effect.
• Consider Antihistamines: For mild, histamine-related reactions, an over-the-counter antihistamine taken before drinking may help reduce symptoms like flushing and nasal congestion.
• Avoid High-Tyramine Foods: If you experience headaches, avoid pairing wine with tyramine-rich foods like aged cheeses and cured meats, as the combination can worsen reactions.

Allergy vs. Intolerance: A Comparison Table

Feature	Wine Allergy	Wine Intolerance	Red Wine vs. White Wine	Trigger Suspects
Immune Response	Yes, involves the immune system releasing IgE antibodies against a specific protein.	No, a digestive/metabolic issue, does not involve the immune system.	Histamine higher in reds, sulfites higher in whites.	Grape proteins, fining agents, yeast, mold.
Onset of Symptoms	Rapid, often within minutes to an hour of consumption.	Can be delayed, appearing hours after drinking.	Red wine may cause faster reactions due to higher histamine.	Sulfites, histamines, tannins, ethanol.
Symptom Severity	Can range from mild (hives, congestion) to life-threatening (anaphylaxis).	Usually mild to moderate (headaches, GI issues, flushing).	Red wines more commonly linked to migraines and flushing.	Ethanol, polyphenols, biogenic amines.
Diagnosis	Skin prick test or blood test by an allergist.	Often through self-observation, elimination diet, or patch test by a doctor.	Tracking what you drink can help isolate specific triggers.	Professional diagnosis is key for certainty.

Conclusion: Navigating Your Sensitivity to Wine

Developing a sensitivity to wine is a real and common occurrence, even for lifelong enthusiasts. Whether it stems from a true allergy to a specific protein or a more widespread intolerance to common compounds like sulfites, histamines, or tannins, the experience can be frustrating. Understanding the different potential triggers and how your body is reacting is the first step toward managing the symptoms. The best approach is to start with careful observation and, if necessary, an elimination diet, guided by advice from a healthcare professional. In many cases, it is not the wine as a whole that causes the problem, but a specific component, which can often be managed by selecting different types of wine or taking simple precautions. For severe symptoms, especially respiratory issues, always seek immediate medical attention. Taking control of your wine sensitivity allows you to continue enjoying the nuances of wine in a way that works best for your body.

Frequently Asked Questions

Why do I get headaches from red wine but not white wine?

Red wine contains higher levels of histamines and tannins, which can cause headaches and migraines in some individuals. White wine generally has lower concentrations of these compounds.

Is sulfite sensitivity common?

While a true sulfite allergy is rare, sensitivity is more common, particularly among asthmatics. White and sweet wines often have higher sulfite levels, not red wines as often assumed.

Can wine intolerance be cured?

There is no cure for an inherited intolerance, as it is a genetic condition. However, symptoms can be managed by identifying and avoiding the specific triggers in wine.

Can I prevent a wine sensitivity from developing?

You cannot prevent an inherited intolerance, but you can take steps to manage or avoid symptoms. This includes abstaining from wine, trying different types, or controlling the amount consumed.

What is 'alcohol flush syndrome'?

Alcohol flush syndrome is a genetically inherited metabolic condition where the body cannot efficiently break down alcohol, leading to an accumulation of toxic acetaldehyde. Symptoms include flushed skin, headaches, and rapid heart rate.

Can allergic reactions to wine be life-threatening?

In very rare cases, a true wine allergy can cause a life-threatening anaphylactic reaction, with symptoms like severe swelling, breathing difficulties, or collapse. These symptoms require immediate medical attention.

Do 'organic' or 'natural' wines have fewer triggers?

Not necessarily. While some producers might add fewer sulfites, other compounds like histamines and tannins are naturally occurring and still present. It depends on the specific winemaking process and ingredients.
