R.A.N.  ( Readily Assimilable Nitrogen ) is the sum of AMMONIACAL NITROGEN and ALPHA-AMINO NITROGEN. They are really important in relation to protein stability and evaluation of the "authenticity" of the wine: ammonia nitrogen may be added to mask the lack of amino acids derived from grapes. The available nitrogen (RAN) is also a factor of great importance to determine whether there are sufficient nutrients in musts to the growth of yeasts responsible for alcoholic fermentation. This method replaces the FORMALIN N° which proved to be carcinogenic! In fact sum of ammoniacal and α-amino nitrogen corresponds to the num-ber of Formolo.
