Used in conjuction with the pH function of either your SC-200 or SC-300 Analyzer, the Yeast Assimilable Nitrogen (YAN) test from Vinmetrica measures the combination of amino acids, ammonium ions, and small peptides. YAN is important as it can contribute to sluggish fermentations and off flavors in your wine.


  • Measures down to 20 mg/L of available nitrogen with accuracy of 10 mg/L of available nitrogen.
  • Enough for 25 tests (only $1.28 per test!)
  • 1 year shelf life


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

I do not own an SC-200 or SC-300 Analyzer. Will a standalone pH meter work with this test?
Peter Stauffer on May 28, 2018
BEST ANSWER: Yes, any properly calibrated pH meter will work.

Gets the job done
Measuring YAN is important so you're able to supplement with yeast nutrients if deficient, or skip it if plenty are available.

not very reliable
I used it and my lab assistant as well and got similar YAN for our must, we had the samples sent off and the test was way off. while easy to sue we found it to not be overly accurate.

Vinmetrica YAN evaluation kit.
The kit workd well, but really needs to come complete with all items shown in the photo. My kit only can with the narrow test tube.

Fast delivery, good instructions, got an answer.
Delivered to California the second day after the order was placed. The instructions were lengthy, but understandable. I took about an hour to complete the first (white) wine, and about 45 minutes to do the (red) second one. The numbers seemed reasonable based on past experience with commercial lab reports.
