Questions About This Product
The things people actually want to know before they cook with it.
Is 5 percent acidity strong enough for pickling?
Yes, and it is the level the standard recipes are written around. The National Center for Home Food Preservation recommends white distilled or cider vinegar at 5 percent acidity for pickling, and this vinegar is labeled at exactly that strength. Heinz also states on the label that the acidity is right for canning and pickling. The important habit is checking the percentage on any vinegar label, since some products on the shelf now run at 4 percent.
Can I use this vinegar for home canning?
Yes. Tested USDA and extension recipes for pickles, relishes and other acidified products assume vinegar at 5 percent acidity, which is what this one supplies. Use it in a recipe that has been tested rather than one you have adjusted, and follow the stated processing method and times. The vinegar meets the acidity requirement, but safe canning still depends on following the whole recipe as written.
Can I water it down to make my pickles less sour?
Not in a canning recipe. Extension guidance is clear that you should not alter the vinegar, water or food proportions in a tested recipe, because diluting the vinegar dilutes the acidity the recipe depends on. If a batch is too sharp for your taste, add sugar instead, which changes the flavor without touching the acid level. Free adjusting of vinegar is only reasonable for refrigerator pickles you plan to eat quickly.
What does 50 grain mean on a vinegar label?
Grain is just another way of writing acidity, and it equals the percentage multiplied by ten. So 5 percent acidity is the same thing as 50 grain, and 4 percent is 40 grain. Older pickling recipes sometimes call for 50 grain vinegar, and a 5 percent bottle like this one is exactly what they mean.
What is the difference between this and cleaning vinegar?
Strength and intended use. Cleaning vinegar is typically bottled at around 6 percent acidity or higher and is sold for household chores rather than eating, while food grade distilled white vinegar like this is standardized at 5 percent. That 5 percent figure is what canning recipes are built around, so cleaning vinegar is not a substitute in the kitchen. Going the other direction, food grade vinegar works fine for the household jobs people use vinegar for.
Do I need a bottle specifically labeled pickling vinegar?
No. Products marketed as pickling vinegar are usually distilled white vinegar at the same 5 percent acidity, sometimes in a larger jug aimed at canning season. What matters for a tested recipe is that the label states 5 percent acidity and the vinegar is a commercial product of known strength. Homemade vinegar and any bottle without a stated percentage should stay out of canning.
White vinegar or apple cider vinegar for pickles?
Both are recommended at 5 percent acidity, so the choice is about flavor and color. Distilled white vinegar is neutral and keeps light colored foods looking bright, which is why it is preferred for cauliflower, onions and fruit. Cider vinegar brings a rounder, fruitier note but will darken the food and the brine. Swapping one for the other at the same acidity does not change the safety of a tested recipe.
What can I use a whole gallon of white vinegar for around the house?
A gallon jug is popular precisely because vinegar gets used in so many small jobs. Common ones are wiping down glass and mirrors with a roughly half and half mix of vinegar and water, running it through a coffee maker or kettle to cut mineral scale, soaking a shower head to clear hard water buildup, and adding a cup to a laundry rinse to help clear detergent residue. Use it on its own with water only, never combined with bleach or any other cleaning product, and note that it is a cleaner rather than a disinfectant or sanitizer.
What surfaces should I keep vinegar away from?
Its acidity is the whole point, and that is also why it does not belong everywhere. Skip natural stone such as marble, granite and travertine, since acid etches and dulls the polish. Also avoid it on waxed or oiled wood furniture, finished hardwood floors, phone and laptop screens, knife blades, and rubber gaskets and hoses, all of which can be stripped, corroded or degraded over time. Warm water with a little dish soap is the usual alternative for those.
Does a gallon of vinegar go bad once opened?
Vinegar is highly acidic and keeps for a very long time when the cap is closed and it is stored in a cool, dark spot. What can happen over months is a hazy look or a soft cloudy blob forming in the jug, which is the mother, a natural byproduct of the fermentation the vinegar came from rather than a sign that something went wrong. It can be strained out with a coffee filter, and it does not affect the acidity for canning.
Can I reuse leftover pickle brine to can another batch?
Not for canning. Used brine has been diluted by the water that came out of the vegetables, so its acidity is no longer the tested strength and it should not go into jars meant for the shelf. Leftover brine is fine for a quick refrigerator batch of onions or cucumbers that you keep cold and eat within a couple of weeks. For anything processed and stored at room temperature, mix fresh brine.
How much pickling can I do with one gallon?
It depends on the recipe, but most cucumber pickle brines run somewhere near equal parts vinegar and water, which puts a gallon in the range of a large canner load or two, roughly a couple dozen pints. Recipes with a higher vinegar to water ratio, such as many relishes and hot pepper pickles, use it up faster. Buying the gallon is generally worth it if you are doing a full canning day rather than a jar or two.
