Vinegar in BBQ Sauce

[cajunboudreaux]

Just wondering on how much vinegar is needed to keep sauce from going bad if not refridgerated??? Have any of you experimented with this, if so please chime in. I have been working on about 4 different sauces and i am very curious on your thoughts.. 
I had never heard of the grape soda sauce before so i tried last week for fun and passed out about 20 jars to friends of 3 different types and that was the one that people spoke of being alittle to vinegar tasting. They really liked the taste but said the vinegar needed to be toned down a tad.. .. Thanks in advance for your help.

Here's the recipe I like for BBQ Sauce. It's Shacks and can be kept with out refrigeration. Every body loves it. I do cut the black pepper in half though. It's a little much for a lot of people.
