Understanding Histamine in Wine: Why Winemaking Choices Matter

Wine headaches prompt various theories. Sulphites get blamed frequently, though the science doesn’t support this for most people. Histamine receives less attention but may offer a more plausible explanation for some reactions to wine.
At Walsingham Estate, our winemaking decisions weren’t made specifically to produce low-histamine wines. We focus on expressing terroir with minimal intervention. For our 2023 vintage, those choices result in wines naturally lower in histamine than many others.
What is Histamine?
Histamine is a naturally occurring compound found in aged and fermented foods, cheese, cured meats, sauerkraut, chocolate, beer, and wine. It derives from the amino acid histidine during fermentation and ageing.
Most people metabolise histamine without issue. Some individuals lack sufficient diamine oxidase enzyme to break down dietary histamine effectively. For these people, histamine-rich foods can trigger headaches, flushing, nasal congestion, skin reactions, or digestive issues.
Wine contains varying amounts of histamine depending on grape variety, fermentation practices, and ageing methods. Understanding what increases histamine content helps identify wines that might be better tolerated.
What Increases Histamine in Wine?
Several winemaking factors affect histamine concentration:
Malolactic Conversion
A bacterial process that converts sharp malic acid into softer lactic acid, occurring after primary alcoholic fermentation. Many winemakers encourage it in red wines and some full-bodied whites to soften acidity and add complexity.
This process increases histamine content. The lactic acid bacteria responsible produce histamine as a byproduct. Red wines typically undergo this process. Some white wines do as well, particularly Chardonnay.
Oak Ageing
Extended ageing in oak barrels can increase histamine concentration. The process allows more time for histamine-producing bacteria to work. Oak itself doesn’t create histamine, but the extended period does.
Skin Contact
Red wines have higher histamine content than whites partly because fermentation involves extended skin contact. Histamine concentrates in grape skins. The longer juice sits with skins, the more histamine transfers into the wine.
Grape Ripeness and Variety
Late-harvest grapes and certain varieties naturally contain more histamine precursors. Very ripe fruit tends toward higher concentrations.
Walsingham Estate’s Winemaking Approach
Our winemaking decisions prioritise expressing what the Stiffkey Valley vineyard produces each vintage. In 2023 these choices created wines that are naturally lower in histamine.
White Wines: No Malolactic Conversion
Our white wines, Solaris, Bacchus and Bacchus Reserve, did not undergo malolactic conversion for our 2023 vintage.
White Wines: No Oak
Our white wines see no oak ageing. We ferment and age in stainless steel to preserve the aromatic character and fresh fruit that defines these varieties.
Bacchus shows elderflower and green apple aromatics. Solaris offers citrus and stone fruit. Oak would obscure these delicate characteristics. The wines are aged on lees briefly for texture, then bottled.
Stainless steel fermentation and minimal ageing mean less time for histamine-producing bacteria to work.
Pinot Noir: Wild Fermentation, Minimal Intervention
Our 2023 Pinot Noir is wild fermented in stainless steel with 14 days on skins. No oak ageing.
Wild fermentation means relying on native yeasts rather than adding commercial cultures. The process is less predictable but can produce more distinctive wines. Our 2023 Pinot Noir came from this approach.
Without oak our Pinot Noir likely contains less histamine than conventionally made red wines, though still more than our whites due to skin contact during fermentation.
Red vs White: The Fundamental Difference
Red wines contain higher histamine than white wines due to extended skin contact during fermentation. If you experience reactions to wine, trying white wines first makes sense.
Among white wines, those without malolactic conversion and oak ageing, like our Solaris, Bacchus and Bacchus Reserve, represent the lowest-histamine options.
What About Sulphites?
Sulphites often get blamed for wine headaches. The science doesn’t support this for most people. Dried fruit contains far more sulphites than wine, yet people who claim sulphite sensitivity rarely react to dried apricots.
True sulphite allergies exist but are rare and typically involve severe respiratory reactions rather than headaches. Sulphite sensitivity is real for some asthmatics. For most people experiencing wine headaches, sulphites aren’t the cause.
Histamine intolerance affects a larger portion of the population than sulphite sensitivity and causes symptoms, headaches, flushing and nasal congestion, that people commonly associate with wine.
Other Factors in Wine Reactions
Histamine explains some wine reactions but not all. Other factors include:
Dehydration: Alcohol is diuretic. Wine consumed without adequate water intake contributes to headaches.
Tyramine: Another amine found in aged foods and wines. Can trigger migraines in sensitive individuals.
Individual variation: People react differently to the same wines. What causes issues for one person may not affect another.
Practical Approach
If you suspect histamine sensitivity:
Start with young, fresh white wines. Avoid oak-aged whites and those that underwent malolactic conversion. Look for wines described as crisp, fresh, or unoaked.
Try wines from cooler climates. These typically have higher natural acidity and less likelihood of secondary fermentation.
Avoid aged reds. Young reds without oak ageing contain less histamine than heavily oaked or extensively aged wines.
Consider winemaking style. Minimal intervention wines made without malolactic conversion offer lower histamine content.
Keep notes. Track which wines cause reactions and which don’t. Patterns emerge.
The Walsingham Estate Range
For those exploring lower-histamine wine options:
Solaris 2023, Bacchus 2023, Bacchus Reserve 2023: White wines without malolactic conversion or oak ageing. Fermented and aged in stainless steel. These represent our lowest-histamine options.
Pinot Noir 2023: Red wine without any oak ageing. Wild fermented in stainless steel. Lower histamine than most red wines, though still higher than our whites due to skin contact during fermentation.
We don’t make specific health claims. Wine affects individuals differently. These descriptions simply explain our winemaking choices and their potential relevance to histamine.
Why This Matters
Understanding histamine in wine helps explain reactions some people experience and offers a framework for choosing wines that might be better tolerated.
We make choices based on expressing terroir and producing balanced wines that reflect their origin. Avoiding malolactic conversion in whites and oak ageing across the range naturally reduces histamine.
Whether histamine sensitivity drives your interest or you simply prefer fresh, unoaked wines, understanding what affects histamine provides useful information.
