Analysis for Yeast Available Nitrogen (YAN)
In a few weeks I will be fermenting wine from Chambourcin grapes that I'm growing in my backyard. Can you please tell me how much you charge for the YAN analysis and what is the turnaround time.

I have attached a link to the enology branch of Penn State Extension. I would also contact Denise Gardener at firstname.lastname@example.org with your question.
From the information that I could find, I am not sure if Penn State does the testing or if it sent to another lab.
