YAN (Yeast Assimilable Nitrogen) Test kit utilizes the pH function of the Vinmetrica SC-200 or Vinmetrica SC-300. The Vinmetrica YAN Analysis Kit gives you confidence to run your YAN tests accurately and quickly. Kit includes everything to perform ~30 tests: Formaldehyde solution, YAN Neutralizing Powder, pipettes, and conical tube.

Testing for YAN just before primary inoculation will allow you to make needed adjustments for a successful fermentation. Yeast Assimilable Nitrogen (YAN) is the combination of amino acids, ammonium ions, and small peptides. Wines with high YAN concentrations typically have increased formation of ethyl acetate, acetic acid and volatile acidity (VA). Wines with low YAN concentrations are more susceptible to a sluggish fermentation as well as production of sulfur compounds like hydrogen sulfide.
