Vinegar Pickle Ratio Calculator

Enter the total brine your jars need and pick a sweetness level to get the vinegar, water, salt and sugar for a classic refrigerator pickle brine.

ml

Roughly what your packed jars will hold in liquid. A quart mason jar of cucumber spears takes about 475 ml, a pint jar about 240 ml.

Five percent acidity vinegar cut half and half with water lands near 2.5% acetic acid, the standard safe range for refrigerated pickles. For shelf-stable canned pickles this brine still needs a tested boiling-water process - do not simply jar it at room temperature.

How the ratio works

The classic refrigerator pickle base is half 5% acidity vinegar and half water, salted at 20 g per liter of finished brine. Sugar is optional: about 15 g per liter for a lightly sweet brine or 40 g per liter for bread-and-butter style. Dissolve the salt and sugar fully, pour hot over packed vegetables, chill, and keep refrigerated.

vinegar = water = total / 2; salt (g) = liters x 20; sugar (g) = liters x (0, 15 or 40)

Frequently asked questions

Is a 50/50 vinegar brine safe for pickles?

For refrigerator pickles, yes: 5% acidity vinegar diluted half and half lands near 2.5% acetic acid, well inside the range home pickling guidance treats as safe while the jars stay refrigerated. Use vinegar labeled 5% acidity and keep the finished pickles cold - this brine is not shelf-stable on its own.

Can I reduce the vinegar for a milder taste?

For refrigerator pickles you can shift toward 40/60 vinegar to water for taste, but the classic 50/50 is the well-documented starting point. Never reduce the vinegar share for pickles you intend to can at room temperature - shelf-stable recipes must follow tested acidity levels and processing times.

Do I need to heat the brine?

Heating helps dissolve salt and sugar and pulls air from whole spices, giving clearer brine and faster flavor pickup. Pour it hot over hardy vegetables like cucumbers, carrots and onions, let the jars cool, then refrigerate. For delicate vegetables, cooling the brine first keeps them crisp.
