Formulas Used

Total Brine Needed

total_brine = jar_count * jar_size_ml * 0.6

Vinegar

vinegar_ml = jar_count * jar_size_ml * 0.6 * vinegar_ratio / (1 + vinegar_ratio)

Water

water_ml = jar_count * jar_size_ml * 0.6 / (1 + vinegar_ratio)

Salt

salt_g = jar_count * jar_size_ml * 0.6 * salt_pct / 100

Total Brine (cups)

brine_cups = jar_count * jar_size_ml * 0.6 / 240

How It Works

How to Calculate Pickling Brine

Formula

Total Brine = Jars x Jar Size x 60% (roughly 60% of jar volume is brine, 40% is produce)

Vinegar = Brine x Ratio / (1 + Ratio)

Water = Brine / (1 + Ratio)

Salt = Brine x Salt %

Vinegar Requirements

For safe water-bath canning, use vinegar with at least 5% acidity. The brine must maintain enough acid to prevent botulism. Never reduce the vinegar below a 1:1 ratio for canned pickles.

Quick Pickles vs. Canned

Refrigerator pickles (quick pickles) can use lower acidity since they are not shelf-stable. Canned pickles must follow tested proportions.

Worked Example

4 pint jars with a 1:1 vinegar-water ratio and 3% salt.

jar_count = 4jar_size_ml = 480vinegar_ratio = 1salt_pct = 3
  1. 01Total brine = 4 x 480 x 0.6 = 1152 mL
  2. 02Vinegar = 1152 x 1 / 2 = 576 mL (about 2.4 cups)
  3. 03Water = 1152 / 2 = 576 mL
  4. 04Salt = 1152 x 0.03 = 34.6 g (about 2 tbsp)
