Allergy to alcohol can vary depending on the nature of alcohol and on the batch, age and label
of the same type
of alcohol or wine. The allergy to
alcohol or to coke even can be due to preservatives, coloring agents, yeast used for brewing, sulfites, gluten products in the alcohol or even to grapes and other bases. It can develop at any time during a person’s life. You need to go for an allergy testing for the ingredients of the beverage you take to know what you are allergic to.
