Why I get itchy hives after drinking certain alcoholic beverages i.E. Beer, some red wine etc but ok with others?  

Tough question . Because wine & beer don't share common ingredients other than alcohol & you tolerate other alcoholic beverages. You might have 2 allergies - hops & something else in wine. Try michelob - supposedly made with rice hops. Is there a pattern to your wine hives - grape variety, region of origin, etc. Or be the designated driver. You may not be the life of the party but you will help save lives.
Allergy. Your hives may be due to an allergy to something in those beverages that make you break out, best to avoid them.
