Hi Dave
Some white vinegar can be as low as 3.5% I almost bought a jug like that at the store
the other day by mistake it was just a cheep generic brand, so yes read the label before you buy.
The 3:1 ratio came from my experiments making shelf stable dill pickles a few years ago.
Nearly every dill pickle recipe you find on the net calls for a 1:1 vinegar/water ratio, so
that is where I started but the brine would start to produce mold on the surface after a week
or so. That probably would work fine if you were canning the pickles or keeping them in the fridge.
But for shelf stable that wasn’t going to work, after some experiments came up with the 3:1
ratio which works very well, I’ve had them stand for 2 years with no ill odors or any sign of
mold or slime on the surface. This is why I thought it work well with a pickled sausage which
already has plenty of salt and cure in it.
The good thing about this tread is we have people asking questions, posting comments, and
hopefully trying to learn something, and that is what these forums are all about, right.
