Regarding the allergic reaction to alcohol,it is usually not the alcohol that produces the allergic reaction to the wine or beer. The other ingredients in the alcohol, such as yeast
, sulfur dioxide, and additives are often the culprits. Beer may contain a variety of ingredients, including barley, corn, wheat, and rye that may precipitate an allergic reaction.
Since the allergens have not been identified in your case,so I would advise you to get allergy testing done.
