A lot of kits contain Chitosan to aide in clearing and I was wondering if anyone knows if this would affect people with a fish allergy? I don't think I have used it on any of my wines but I would hate to forget and give a bottle of wine to someone that may be affected by it.
 
I have a shellfish allergy and have never had a reaction... I am by no means an expert on the chemistry but apparently the processing denatures the proteins, which are the source of the allergies...
