However, these effects are of various types and its effects are entirely depending on the individual. Many persons are noticed to have allergic reactions after consuming alcoholic drinks and such reactions are popularly known as wine, beer or alcoholic Alergy. The alcohol or ethanol as it is also known is broken down by the liver enzymes just within a few minutes of its consumption.

These liver enzymes are known as Alcohol Dehydrogenase that converts alcohol or ethanol into acetaldehyde. Acetaldehyde is then transferred to vinegar by these enzymes, and if the person’s liver is unable to break down the alcohol easily and yet alcohol is consumed, problems known as alcohol allergy may develop. Antibiotic and antifungal medications may reduce the effect of Alcohol Dehydrogenase and may cause the oriental flush syndrome.

Many of the ingredients of wine and beer are responsible of causing the allergic reaction.
