    FG/CG diff

    Fine grind represents the max. amount of extract that would be obtained in a lab. Coarse grind is the max. amount you would get with the typical grind most brewers use, if your efficiency was 100%. The difference should be less than 1.5%, higher numbers can indicate under modified malt. Here in North America, that is rarely seen. Check with your malt supplier for more info. on deciphering malt analysis....

    Cheers!

      Agree with pbutlert

      I agree with the comment by pbutlert. It is a way for the lab or brewer to assess whether or not the milling conditions are optimal. Unless you want stuck mashes you would never go to a fine grind (basically flour with no husks for filtration) in the brewhouse itself. The ratio FG/CG just gives you the goods on what you could attain as a theoretical 100% efficiency vs. the optimal brewhouse efficiency.

        Modification

        The difference between the two was used earlier as a method for determining how well modified malt was (i.e. the extent the cytolytic processes were allowed to work during malting). It is not used much anymore, and in fact has been taken out of the European analysis methods for determining malt quality, because measuring the viscosity, among other things, is much more accurate. The difference between the two is supposed to be low, because if it's not, then the malt still contains lots of the cellular framework which should have been broken down during malting.

          Extract fine and extract coarse are separately got by elaborate and different standard (ASBC, EBC, IOB) procedures.
          This is one of the indexes for malt modification.
          The most characteristic one for the modification is the percentage of soluble nitrogen of whole nitrogen, or Kolbach index.
          The extent of malt modification is not an absolute merit i.e. the higher the better. Beer style -> mash procedure -> malt (specification) is a proper way of decision making.

            FG/CG is an index for malt modification. FG alone is a base for calculating the efficiency. 100% efficiency is not a theoretical but just standard, for congress mashing. Efficiency of more than 100% are known in the industry.

                  Meura 2001 - mash filter, gives 102-106%. But regular MT and LT also give up to 99%.
