I make this mayonnaise based sauce that my friends all rave over and I wanted to make a large batch, can it (which I've never done before) and give it out as a gift. I'm nervous about giving away something without understanding how long it can be preserved in the refrigerator.

The sauce has 1 part white wine vinegar, 1 part water and 6 parts mayonnaise, in addition to minced garlic and other spices. Any ideas on how long this might last, or where I can find better literature about preserving in general?
