“No headache and my wine taste better!” says one five-star review on Amazon aboutUllowine purifiers. Another user who reviewedPureWineraves, “This product is awesome. Swish it in your wine, and it doesn’t affect the taste of the wine at all. Results: Flat-out works. No headaches!”
In sharp contrast, you can find some reviews of wine purifiers stating that the device “does nothing” and “it made very little difference and altered the taste of most of the wines.”
Would putting your wine through a purifier help remove impurities, or is this just another gadget with a marketing gimmick? We delved into the science behind alcohol-induced headaches and spoke with some wine experts for their insight.
Is Wine Healthy? Here’s What Dietitians Have to Say
Wine purifier makers claim that their products can filter out impurities, mainly sulfites, to make the wine more “clean.”
While no brand proclaims that their wine purifiers prevent headaches, they imply that using their products would reduce the chances of unpleasant symptoms that come with drinking wine.
What Happens to Your Body When You Drink a Glass of Wine Every Night
Researchsuggests that alcohol in general may trigger inflammation in a particular part of the brain and the blood vessels surrounding the membranes that protect the brain. This inflammation manifests as painful headaches.
Among the alcohol varieties,red winetriggers more headaches than other alcoholic drinks, which could be due to the compounds present in red wine, including but not limited to sulfites. Histamines as well as flavonoids may also contribute to headaches.
I Just Found Out Most Wine Is Full of Chemicals—Here’s What You Need to Know
Flavonoids, such as anthocyanins and tannins, are antioxidants and pigments in red wine that give it color, flavor and mouthfeel.Researchnotes that flavonoids might block an enzyme, phenol sulfotransferase (PST), in the body. As a result, the body cannot rid itself of certain substances in alcohol that pass from the bloodstream to the brain, leading to headaches.
The same study also points out that people who have low PST enzyme activity in their blood may have a higher chance of experiencing red-wine-induced headaches.
When it comes to histamines, they’re present in the body when the immune system suspects a potential allergen. Histamines are also naturally found in foods, and have higher concentrations in fermented and aged foods, such as aged cheese, sauerkraut and red wine. Most people can tolerate them, however, a small percentage of people areintolerant. In this case, histamine may build up in the body, putting these individuals at a greater risk of experiencing headaches, due to the immune system’s response.
Now, on to sulfites. Since sulfites are naturally in wine and added as an additive, theU.S. Alcohol and Tobacco Tax and Trade Bureaurequires winemakers to declare sulfites on the label when there are more than 10 or more parts per million sulfites present. This statement is meant to inform consumers who may be allergic to sulfites and have asthma, as they may also be sensitive to sulfites.
Science suggests that people with lower PST enzyme activity levels and underlying sensitivities to histamines and sulfites may be at a greater risk of having alcohol-induced headaches. However, current evidence has not proven that histamines and sulfites can cause alcohol-related headaches if you do not have an intolerance to them.
5 Health Benefits of Drinking Wine
The relationship between compounds present in wine and wine-induced headaches remains debatable.
A 2019studypublished in theEuropean Journal of Clinical Nutritioninvestigated the relationship between sulfites and wine-induced headaches. This study involved 80 people and found that the concentration of sulfites present in wine may be linked to headaches.
However, James Fairbrother, cellar manager atArdesia Wine Barin New York City, argues, “There are fewer sulfites in wine than [in] most juices and dried fruits.”
For example, dried fruits can contain up to 1,000 ppm of sulfites per serving, whereas red and white wine only have about 160 ppm and 210 ppm, respectively.
More importantly, “Wine purifiers are not the solution to all your headaches,” says sommelier Bertil Jean-Chronberg, owner of Bonde Fine Wines in Cambridge, Massachusetts. He suggests that there are simple ways to reduce headaches without using a filter, such as choosing wines with the lowest possible levels of alcohol and residual sugar.
Jean-Chronberg adds, “The lower the alcohol content of the wine, the lower the chance of a residual sugar level.”
Lastly, while experiencing dehydration is not a red-wine-specific phenomenon, those who drink too much alcohol may havehangover headaches, which occur within 5 to 12 hours of consumption. The reason is thatalcoholis a diuretic, making one urinate more and leading to mild dehydration, thirst and tiredness.
