TA 4.42 g/L
Added 2 g/L Tartaric Acid, pH now 3.54
NaOH standardize to 0.01N HCl acid.
I tested for Malic Acid but I do not believe the result. I will try again w Riesling and Pinot Gris.
YAN estimate at 50 mgN/L
My spread sheet uses a value of 160 mgN/L for Fermaid O. It is rated to be equivalent to (160 to 240 mgN/L). Therefore a build in safety factor.
