Understanding Histamine in Wine
Histamine is a natural compound formed during the fermentation and aging process of wine through the action of bacteria, particularly during malolactic fermentation. Your body uses an enzyme called diamine oxidase (DAO) to break down histamine. However, some people have a deficiency or a lower-than-normal amount of this enzyme, leading to histamine intolerance. When these individuals consume wine, the excess histamine can trigger a variety of symptoms, including headaches, flushing, nasal congestion, and gastrointestinal upset. The amount of histamine can vary drastically, and it is not just present in red wine; traces exist in all fermented beverages.
Factors Influencing Histamine Levels
Several factors during winemaking contribute to the final histamine concentration, which is why some wines are tolerated better than others.
- Grape Variety and Skin Contact: Histamine is primarily found in the skins of grapes. Wines made from thick-skinned red grapes, such as Cabernet Sauvignon or Syrah, and those with prolonged skin contact during fermentation, will have higher histamine levels. In contrast, white wines and rosés have little to no skin contact, resulting in much lower histamine content.
- Malolactic Fermentation: This secondary fermentation process converts tart malic acid into softer lactic acid. It is almost always performed for red wines but is optional for whites. Lactic acid bacteria, which drive this process, are significant histamine producers. Avoiding wines that have undergone malolactic fermentation is a key strategy for reducing histamine intake.
- Aging and Storage: Older, barrel-aged wines, especially reds, tend to have higher histamine concentrations. Wooden barrels are difficult to sterilize and can harbor bacteria that increase histamine over time. Young, fresh wines fermented in stainless steel tanks contain less histamine because the cleaner environment limits microbial growth.
- Hygiene and Control: Wineries that maintain meticulous hygiene and use specific, non-histamine-producing yeast and bacterial strains during fermentation can produce wines with significantly lower histamine levels. This level of control is often a hallmark of certified low-histamine wines.
Best Wine Choices for Histamine Intolerance
When navigating the world of wine with histamine intolerance, the general rule is: the less 'red' the wine, the better. This prioritizes white, rosé, and some lighter reds.
- White Wines: Your safest bets are typically dry, young, and unoaked white wines. These are less likely to undergo malolactic fermentation and have minimal skin contact.
- Sauvignon Blanc: Often crisp and fresh, Sauvignon Blanc is fermented without skins and typically does not undergo malolactic fermentation.
- Pinot Grigio / Pinot Gris: This thin-skinned grape variety yields wines that are usually fresh, crisp, and low in histamine.
- Riesling: Especially dry, young German Rieslings are excellent choices due to minimal skin contact.
- Unoaked Chardonnay: While some Chardonnays undergo malolactic fermentation for a buttery flavor, unoaked versions fermented in stainless steel tanks are a safer bet.
- Rosé Wines: Generally, rosés are fermented with minimal skin contact, making them a suitable, low-histamine option. Lighter-colored, younger rosés are ideal.
- Sparkling Wines: Cava and Prosecco tend to be lower in histamine than many still reds. Aged Champagnes should be approached with caution due to longer aging on lees, which can increase histamine content.
- Red Wines: If you must have red, opt for a younger, lighter-bodied varietal.
- Pinot Noir: A notoriously difficult grape to grow, Pinot Noir has thinner skins than most red grapes, potentially resulting in lower histamine levels, especially in younger vintages.
- Specialty Certified Low-Histamine Reds: A few producers have developed certified low-histamine red wines using meticulous production techniques, such as Veglio Michelino e Figlio's Dolcetto D'Alba or Barbera D'Alba.
Comparison Table: High vs. Low Histamine Wines
| Feature | Low Histamine Wine | High Histamine Wine |
|---|---|---|
| Wine Type | Dry White, Rosé, Sparkling | Aged Red, Fortified Wines, Dark Beer |
| Grape Skins | Thin-skinned (e.g., Riesling) | Thick-skinned (e.g., Cabernet, Syrah) |
| Fermentation | Shorter, in stainless steel | Longer, often with malolactic fermentation |
| Aging | Young, fresh, unoaked | Aged in wooden barrels |
| Typical Histamine Content | Low (3-120 µg/L) | High (60-3800 µg/L) |
| Examples | Sauvignon Blanc, Pinot Grigio | Merlot, Cabernet Sauvignon, Port |
How to Enjoy Wine with Histamine Intolerance
Beyond choosing the right bottle, you can take other steps to minimize your symptoms. The key is moderation and being mindful of your body's individual response.
General Tips
- Watch Your Portion Size: Smaller quantities are less likely to overwhelm your body's DAO enzyme supply. Start with a small amount to gauge your tolerance.
- Limit High-Histamine Foods: Consuming wine with other high-histamine foods, like aged cheeses or fermented products, can increase your total histamine load and worsen symptoms.
- Stay Hydrated: Drinking water alongside your wine can help. Remember that alcohol itself inhibits the DAO enzyme, so hydration is always important.
Advanced Options
- Certified Low-Histamine Wines: Look for producers in Europe, particularly Germany and Italy, who have begun producing wines tested and certified to contain less than 0.5 mg/L of histamine. Some brands even provide analysis results on their websites.
- Wine Purifiers: Some products, such as filtering wands or sachets, claim to remove histamines and sulfites from wine after opening, though their effectiveness can vary.
Debunking Myths about Wine and Histamine
- Myth: Organic wine is low in histamine. Fact: Histamine is a natural byproduct of fermentation and can be high even in organic wines, as the organic label only refers to farming methods.
- Myth: Sulfites cause wine-related headaches. Fact: While some people are sensitive to sulfites, research shows that histamines are a more common trigger for the typical red wine reaction, like flushing and headaches.
- Myth: Histamine can be completely filtered out. Fact: Histamine molecules are extremely small and cannot be completely filtered from wine. While specialized products can reduce levels, choosing a wine with naturally lower histamine content from the start is more effective.
Conclusion: Finding Your Best Wine for Histamine Intolerance
Navigating wine options with histamine intolerance is about prioritizing lighter colors, less aging, and controlled fermentation. White wines like Sauvignon Blanc and Pinot Grigio are the most reliable choices, while younger rosés also present a low-risk option. If you crave a red, seek out young Pinot Noir or explore the growing market for specially certified low-histamine wines from producers in Europe. By understanding the factors that influence histamine levels, you can make informed choices and reclaim your enjoyment of a glass of wine with fewer side effects.
