Water, salt and vinegar and sometimes sugar are combined and heated and then fruit or vegetables are immersed in that liquid. However, there is a lot of variation within those ingredients that needs to be taken into account. According to Eugenia Bone , author of Well-Preserved: Recipes and Techniques for Putting Up Small Batches of Seasonal Foods , the most important thing about vinegar is its five percent acidity, which causes changes in flavor and texture and acts as a preservative.
In terms of which vinegar to use, it depends on the desired taste and color of your pickles. Distilled white vinegar and white wine vinegar are most popular because they won't affect the color of most vegetables red onions, however, will turn bright pink when exposed to white vinegar.

Do not use homemade vinegar or vinegar of unknown acidity in pickling. Do not dilute the vinegar unless the recipe specifies, because you will be diluting the preservative effect. If a less sour product is preferred, add sugar rather than decrease the vinegar.
So Easy to Preserve. University of Georgia Cooperative Extension. Bulletin Sixth Edition. The strength of a consumer-grade vinegar is measured by what concentration of acetic acid is in it.
And while you are at it, be sure to ask them what vinegar strength you would arrive at after following their dilution instructions. Be sure to measure precisely. In North America, spiced pickling vinegars are not common. Instead, the practice is to take vinegar, and add your own pickling spice as part of the recipe. In Europe, already spiced and seasoned pickling vinegars are sold next to plain pickling vinegars.

Apple cider vinegar, made from fermented apple juice is a good choice for many pickles. It has a mellow, fruity flavor that blends well with spices. However, it will darken most vegetables and fruits. Cider vinegar may be substituted for white vinegar of the same acidity.

These are salad vinegars and are not strong enough to make good quality or safe pickles for home canning. Use pickling or canning salt without iodine or anti-caking agents. Other salts contain anti-caking materials that may make the brine dark and cloudy.

The water you use may impact the final product. Hard water can interfere with the formation of acid and prevent pickles from curing properly. Water with above-average calcium content can shrivel pickles, and iron compounds can make them darker than normal. To soften hard water, boil for 15 minutes and let it sit undisturbed for 24 hours and discard sediment; add 1 tablespoon vinegar per gallon of water before using. Chlorine in municipal water does not negatively impact the quality of the final product.
However, do not reuse brine mixed with vegetables. The vegetables soak up the vinegar solution making them acidic while making the pickling solution less acidic.
For safety sake, do not use leftover brine that previously held vegetables for another recipe.
