TOXIC HOME BREW ?

HEALTH WARNING TO HOMEBREWERS . I used LIQUIFRUIT RED G**** to make red wine which gave off a bad smell of rotten eggs and I believe is Toxic . I asked Pioneers Help Line (***-07-140) to refer this to a qualified Food Chemist for INVESTIGATION as I suspect possible Sulphur contamination. Their response was inadequate , unconcerned and pathetic.
