Red wine headache is a headache
Headache
A headache or cephalalgia is pain anywhere in the region of the head or neck. It can be a symptom of a number of different conditions of the head and neck. The brain tissue itself is not sensitive to pain because it lacks pain receptors. Rather, the pain is caused by disturbance of the...

Sulfites

Since wines contain a warning label about sulfites many people have assumed that sulfites are the cause of RWH. This is not the case. Almost all wine contains sulfites. Many sweet white wines have more sulfites than red wines. Dried fruit

 and processed food like lunchmeat have far more sulfites than red wine. Less than 1% of the population is sensitive to sulfites.

There are sulfite sensitive individuals who have asthma problems from red wine and dried fruit (such as apricots and golden raisins) that have added (not just natural) sulfites. Some of these sulfite sensitive individuals generally do not have asthma problems from red wine that only has sulfites naturally inherent to the grapes.

Histamines

RWH is probably not caused by histamine

. Again, if histamine is not the cause of a given individual's reaction to wine, the antihistamine effects of black tea will be of no more help than the antihistamine effects of loratadine, just as in the example of the previous paragraph.

Tannins

Other experts think tannins are at the root of RWH. Tannins are the flavonoids in wine that give its degree of mouth-drying bitterness. The taste is the same as when you bite into a grape skin. Tannin is a chemical substance that comes from grape skins, stems, and seeds. The skins also impart color to wine, which is why red wines typically have a lot more tannin than whites. Red wines are fermented while in contact with the skins and seeds. Modern winemakers take care to minimize undesirable tannins from seeds by crushing grapes gently when extracting their juice.

Wines can also take on tannins from the oak or other woods used in wine barrels for storage. Different woods in different countries affect the type of tannins in the wine.

Tannins help prevent oxidation, an important role in a wine's aging potential. As age-worthy red wines mature, tannin molecules gradually accumulate and precipitate out of the wine in the sediment.

Certain wine styles have much less tannin content than others, due to reduced maceration time (grape juice contact with the grape pulp, including sources of tannin such as stems, seeds).

 are also lower tannin wines.

A quick way to identify these lower tannic wine bottles on a store shelf is to look for the sloped shoulder "Burgundy bottle". This is specially true for European wines, but several new world wineries have also adopted traditional bottle shapes to help consumers distinguish their wines.

There is a difference between the varieties and brands of red wine and the amount one can consume before the headache occurs, but the reports have not been consistent from person to person. Considering how the amount of tannins changes with aging, this would not be surprising.

, added that no one complains about tea, soy, or chocolate headaches though all contain tannins.

The tannins that are extracted from grapes found in red wine are primarily condensed tannins which are polymers of procyanidin monomers. Hydrolysable tannins are extracted from the oak wood the wine is aged in. Hydrolysable tannins are more easily oxidised than condensed tannins.

Prostaglandins

RWH could be caused by the release of prostaglandins which some people are not able to metabolize. Prostaglandins are substances that can contribute to pain and swelling. Ibuprofen

 (Advil), acetaminophen (Tylenol) and aspirin are prostaglandin inhibitors. Some people get good results taking a dose of an inhibitor an hour before consuming red wine. Aspirin and ibuprofen were shown to be effective at blocking both early and late stages of the RWH, and acetaminophen was effective in blocking the early stage. It should be noted that acetaminophen and alcohol are not good for the liver, and can be potentially harmful.

Tyramine

Tyramine may well be a major player in RWH syndrome. Tyramine is an amine that is produced naturally from the breakdown of protein as food ages. More specifically it is formed by the decarboxylation of the amino acid tyrosine. It is found in aged, fermented, and spoiled foods. Everyday foods we consume including aged cheeses, overripe and dried fruit, sauerkraut, soy, and many processed foods contain high levels of tyramine. Tyramine is suspected of inducing migraine headaches in about 40% of migraine sufferers, according to Dr. F.G.Freitag of Diamond Headache Clinic in Chicago.

Dr. Lynn Gretkowski, co-founder of WineDoctors.com states that tyramine could be the cause of RWH. Last year, she told The Wine Spectator (May 31, 2009), “Tyramine is thought to be a vassal active substance that causes the dilation and contraction of blood vessels - the squeezing and relaxation component of headaches.” She goes on to say that younger wines and wines that have not been extensively racked or filtered will tend to have higher rates of tyramine. Not all wine has the same level of tyramine present so not all red wine causes RWH symptoms.

While tyramine has not yet been definitely proven as the source of the Red Wine Headache, it seems to be a more probable cause than sulfites or histamine.

It has also been postulated that RWH could be caused by a strain of yeast
