"For people with allergies and asthma, toasting the New Year could result in more than a hangover; it could also set off a variety of unpleasant reactions, warns an organization of allergists.
 
"It is usually not the alcohol itself that produces the reaction. It is most likely ingredients, such as sulfur dioxide metabisulfite, yeast and additives. Common allergic reactions include hives, skin rashes, flushing and warmth of the skin, bronchospasm or shortness of breath, especially in those with asthma," Dr. Clifford W. Bassett, chairman of the American Academy of Allergy, Asthma & Immunology's Public Education Committee, said in a news release."
