Replacing Acid Blend / Citric Acid with Grape Concentrate

[hill1649]

I am adding 250 mls Grape Concentrate per gallon to my country wines (dried flower and berries) - do I still need to add the Citric Acid or Acid Blend or does the concentrate contain enough acidity?

I think the grape concentrate is used to add "vinosity" (Webster: the characteristic body, flavor, and color of a wine). There is some nutrient present (how much?) but I would think a teaspoon of citric acid won't do any harm if the berries are not acidic.
