      Looked up 'Making Wine', B. Rankine:
      "The mecahanisms of fining can be quite complex and are usually
      oversimplified. The simplest explanation is that of electrostatic
      attraction, whereby the fining carrying a particular electric charge
      reacts with wine constituents carrying the opposite charge and the
      neutralised combination precipitates."
      e.g. the reaction between positively charged gelatin and negatively
      charged tannin and phenolics.
      Dosage rate for gelatin is 0.05-0.15 grams/litre
