YAN Test Kit

$32.00

YAN (Yeast Assimilable Nitrogen) Test kit. Utilizes the pH function of the Vinmetrica SC-200 or Vinmetrica SC-300.

Product Description

In our effort to bring you the latest in wine analysis, the Vinmetrica YAN Test kit is now available! 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.

The YAN Test Kit utlizes the pH function of either your SC-200 or SC-300 and includes:

1. YAN Reagent (37% Formaldehyde/15% methanol, Part Number SC-200-14-1)
2. YAN Formaldehyde Neutralizer Powder (Sulfite, Part Number SC-200-14-2)
3. Three Plastic Transfer Pipettes (SC-100-5)

 

Specifications

  • Measures down to 20 mg/L of available nitrogen with accuracy of 10 mg/L of available nitrogen.
