What is the purpose of citric acid in wine? I have seen a few recipes with it and a few without it. From what i can see i should add it to wines without citrus fruits in it? Would it be a major issue if i left it out.
 
i think what it does in the end is means that there will be less of a bite. but i could be wrong. i always add cirtic acid when its asked for.. e.g. Rosehip wine. because rosehips arn't acidic.
 
Firstly, yeasties work best in a slightly acidic environment.

Secondly, your taste buds will respond better to a wine with a bit of acid and tannin.

I understand from Wurzel that the correct term for a wine which is lacking in those factors is “flabby”, but go too far and you'll end up with something like a cheap Hock. Where fruits are high in acid (rhubarb, grapefruit, etc.) you might want to add some chalk to bring it down. Where fruits, veggies etc. are low in acids you will need to add some to get the balance right.


PS: Good link, thanks Neil :cheers:
