You can reduce histamines in wine using commercial filter devices, fining agents, or by choosing wines that are naturally lower in histamines. No method eliminates histamines completely from a glass already poured, but several approaches meaningfully lower the amount you consume.
Why Wine Contains Histamines
Histamines form in wine when certain bacteria convert the amino acid histidine into histamine during fermentation. The main culprits are lactic acid bacteria, which carry a specific gene for the enzyme that drives this conversion. The process happens primarily during malolactic fermentation, a secondary fermentation step that softens a wine’s acidity and adds complexity. Nearly all red wines go through this step, which is one reason reds tend to carry more histamine than whites.
White wines typically contain less than 1 mg of histamine per liter. Red wines often contain three to four times that amount, though the range varies enormously. Two Pinot Noir wines tested in one study differed by a factor of 30: one had 13.8 mg/L while the other had just 0.4 mg/L. The specific bacterial strains present during fermentation matter far more than the grape variety alone.
How Much Histamine Is Actually a Problem
Wine is considered a relatively low-histamine food overall, and most people process small amounts without any issues. Your body breaks down histamine using an enzyme called diamine oxidase (DAO). The trouble starts when that system gets overwhelmed or impaired. Alcohol itself makes this worse in two ways: it triggers the release of histamine from immune cells called mast cells, and it directly suppresses DAO activity. So even a modest amount of histamine in wine can cause outsized reactions because the alcohol is simultaneously flooding you with more histamine while disabling the enzyme that clears it.
Some sensitive individuals react to concentrations as low as 0.08 to 0.15 mg/L, which translates to roughly 15 to 30 micrograms per glass. There are no universal legal limits for histamine in wine, but several countries have set recommended thresholds. Germany and the Netherlands recommend levels below 2 mg/L. France, Belgium, Switzerland, and Australia set their guideline at 8 to 10 mg/L. There is no official definition for “histamine-free” or “low-histamine” wine anywhere in the world.
Commercial Wine Filters and Drops
The most accessible option for consumers is a commercial wine purifier, such as filter wands or pouches you place directly in your glass or bottle. These devices use ion-exchange resin technology: tiny polymerized granules that swap charged particles in the wine. The resins combine both cation and anion exchange materials with chelating agents, allowing them to bind histamines and other biogenic amines along with sulfites. The ions in the wine are exchanged for other ions of the same charge while the resin itself stays intact in the device.
These products do reduce biogenic amines and sulfites to some degree, but they also pull out other charged compounds in the wine, including certain metals like iron, copper, calcium, and potassium. That can shift the wine’s pH, its color intensity, and potentially its flavor. Red wines tend to be more noticeably affected than whites because they have more complex chemistry to begin with. If you’re using a filter wand, follow the recommended contact time closely. Leaving it in too long strips more flavor compounds; pulling it out too early reduces its effectiveness.
Liquid wine drops work on a different principle. Most sulfite-removing drops use a reducing agent to neutralize sulfur dioxide specifically, and some brands combine this with ingredients targeting biogenic amines. Read labels carefully, because many “wine sensitivity” drops only address sulfites, not histamines.
What Winemakers Do During Production
At the production level, the most effective tool for removing histamines is bentonite, a type of clay used as a fining agent. Bentonite adsorbs histamine and other biogenic amines from the wine matrix and is then filtered out. It is already standard practice in white winemaking to prevent haze from unstable proteins. The tradeoff is that bentonite also strips volatile aroma compounds, which can flatten a wine’s bouquet. This is why winemakers use it cautiously and why it is less common in premium red wine production.
Researchers have also tested functionalized silica, a more targeted adsorbent designed to grab biogenic amines while leaving other wine components relatively untouched. This technology shows promise but is not yet widespread in commercial winemaking.
Another production-level strategy involves controlling which bacteria are present during fermentation. Winemakers can now screen bacterial cultures for the histamine-producing gene using PCR testing before inoculation, selecting only strains that lack it. Co-inoculating the malolactic bacteria at the same time as the primary yeast fermentation, rather than adding them sequentially, has also been shown to reduce biogenic amine levels compared to the traditional approach.
Choosing Lower-Histamine Wines
If you’re trying to avoid histamines rather than remove them, your wine selection matters more than any filter. Here are the general patterns:
- White over red. White wines average less than 1 mg/L of histamine. Reds run three to four times higher because they undergo malolactic fermentation and have longer skin contact during production.
- Younger over aged. Histamine levels can increase during extended aging, particularly in barrel-aged reds where bacterial activity continues slowly.
- Controlled fermentation over natural. Wines made with carefully selected bacterial cultures are less likely to contain histamine-producing strains. Natural or “wild” fermentations are unpredictable in this regard.
- Cooler-climate whites. Unoaked Chardonnay, Riesling, Sauvignon Blanc, and other crisp whites that skip malolactic fermentation entirely tend to be the safest choices.
Some producers now market wines as “low histamine,” but without any regulated definition or certification standard, that label is essentially self-reported. A few specialty retailers test their wines independently, which is more reliable than a producer’s marketing claim alone.
What Actually Helps at Home
Chilling wine does not remove histamines, and neither does decanting, aerating, or letting a bottle “breathe.” These are common suggestions online, but histamine is a stable molecule in wine’s pH range and does not evaporate or break down with air exposure. The only approaches that physically reduce histamine in a poured glass are ion-exchange filters and adsorbent-based products.
Taking a DAO supplement before drinking is a different strategy that some people find helpful. Rather than removing histamine from the wine, these supplements provide extra enzyme to help your body break down whatever histamine you consume. They do not address the fact that alcohol itself triggers histamine release from your own cells, so they are only a partial solution.
If you react to wine consistently, it is worth noting that histamine may not be the only trigger. Wine contains sulfites, tyramine, and other biogenic amines that can cause headaches, flushing, and nasal congestion through entirely separate pathways. A product that removes only histamine may not resolve your symptoms if another compound is the primary cause.
