YAN (Yeast Assimilable Nitrogen)

  • Purpose:

    Yeast Assimilable Nitrogen (YAN) is quantitative analysis for both organic nitrogen (PAN/FAN) and inorganic nitrogen (Ammonia/Ammonium) combined into one value. It is an important value when determining quality of must or nutrient deficient fermentations and how much nutrient additions are necessary. When using a combination of nutrients containing both organic and inorganic nitrogen, this is the preferred testing method.
