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.

Elegant Bastard is a wonderful brew and I will brew it again. The kit contains one pound of corn sugar which serves only to increase the alcohol content. I would replace this with a pound of dry light malt extract.
Please stop asking me about the citric acid. Three times. It's only citric acid.
