Citric Acid can be used in sanitizing solutions to lower the pH, which will make the SO2 level more effective. It is also used to increase acidity at a ratio of 0.1% for each teaspoon per gallon in wine. Be careful with how much you add to your wine because you will get a very tart flavor if you use to much.
This works well to help lower the pH of wine. Measure well because unlike other acids this can change the wines flavor.

Add acidity to Wine and Mead
When I add acid, I add mostly Citric, with a touch of Malic and Tartaric to round it out. I wouldn't dream of doing this without a pH meter.

pH adjustment
I use several acids to adjust my Wines pH rather than rely on a blended powder, so I have more control. Citric acid is noticeable above a not so low threshold so add a little at a time in a sample then scale up.
