Tool for the Ammonium ISE in wine

In the must during the alcoholic fermentation, yeasts need nitrogen and oxygen for their basic nutritional needs and growth. The power of yeast nitrogen is supplied by the ammonium ion and the amino acids. Insufficient water supply nitrogen in the vineyard or a too dry summer season can cause a deficiency of assimilable nitrogen in the must. The ammonium cation is particularly assimilable and can meet all the needs from only the yeast, including the synthesis of amino acids. The control of ammonia through the analysis of musts is one of the most important factors to ensure the good performance of the alcoholic fermentation of vini.Quando presents values ​​below 25 mg / l of ammonium cation or 160 mg / l of nitrogen similar (ammonium cations more amino acids except proline), a must must be added ammonia nitrogen (diammonium sulfate or diammonium phosphate). Thanks to HI 84185 is now possible to know the initial content of ammonium ion in the wort, in a simple and accurate, and can thus assess the appropriateness of proceeding with an enrichment of ammonia salts.
