Made an interesting mistake this last weekend...
I used the sringe and technique from one kit - 15cc wine, start with
Turns out technique 1 used NaOH with 0.2 normality and the other used
Is there a formula for TA that includes a variable for the Normality of NaOH so I recalc what my starting acids were?
thx, dan
Use this formula... %(W/V) = 7.5x(VbxN)/VwxF) Vb = ml of naoh used Vw= ml of wine used N= normality of NaOH F= normality factor if NaOH is not .1N >
TA = 75 * N * Vn / Vs
where TA = titratable acidity (as tartaric acid (g/l)) N = Normality of NaOH (0.2 in your case) Vn = Volume of NaOH (ml) Vs = Volume of sample (ml)

Thanks Greg.
What is F, the normality factor? If I used .2N would this be 2? dan
It would be .2
2 would be almost a 10 % solutionBTW the formula is in Margalits handbook for small wineries page 160 . Great book that covers making wine in small wineries .
