title_body: Does use of Isinglass require special mention on the beer?
upvoted_answer: NO.
  
  In 2003, the EC discussed requiring labeling for Isinglass as a potential food allergen.
  
  The brewers in the EC successfully argued that it was part of the processing and not an additive and thus did not require labeling. 
  
  
    Isinglass finings are a tried and tested method of clarifying beer and so it came as a great relief to traditional cask ale brewers when the EC, last year, introduced an amendment to the 2003 labelling directive. The brewing industry successfully argued that as a processing aid, not an ingredient that would be consumed, and with a long history of use with no recorded incidents of an allergic reaction, there was a good case for isinglass to be exempt from the directive.
