vinegar and wine is a BAD idea!!!!!!!! even CO2 produced by vinegar and soda still has a vinegar smell. You don't want vinegar anywhere near your wine. a better alternative would be lemon juice... or acid blend in water would be better still. The acids in lemon juice and acid blend, when mixed with baking soda, will create the same reaction, but these are things we use in wine and contamination would not be an issue.
