In the future, do acid trials with a 20% solution (20g tartaric brought
to a volume of 100ml), and use .10ml of 20% sol./50ml of wine to add the
equivalent of .05g/100ml to your wine.
Have you had your wine with food, or is this to be a sippin' wine?
How much of what did you add? Malic is more sour than tartaric, for
example (it drops the pH more than an equivalent amount of tartaric).
Have you titrated for total acidity, pH?
