Formulas Used

White Vinegar (5% acidity)

vinegar_ml = round((pickle_type == 1) * brine_ml * 0.5 + (pickle_type == 2) * brine_ml * 0.5 + (pickle_type == 3) * brine_ml)

Water

water_ml = round((pickle_type == 1) * brine_ml * 0.5 + (pickle_type == 2) * brine_ml * 0.5 + (pickle_type == 3) * 0)

Pickling Salt

salt_g = round(brine_ml * 0.03)

Sugar

sugar_g = round((pickle_type == 2) * brine_ml * 0.15)

How It Works

How Pickling Brine Is Calculated

Standard Ratios

  • Dill pickles: 50% vinegar (5% acidity), 50% water, 3% salt.
  • Bread & butter: 50% vinegar, 50% water, 3% salt, 15% sugar.
  • Quick pickles: 100% vinegar, 3% salt. Refrigerator only (not for canning).

    • Safety

    For shelf-stable canning, the brine must contain at least 50% vinegar with 5% acidity. This ensures a pH below 4.6, which prevents botulism. Quick pickles stored in the fridge are safe with any ratio but will not keep as long.

    Worked Example

    Make 4 cups of standard dill pickle brine.

    brine_cups = 4pickle_type = 1
    1. 01Total brine = 4 x 240 = 960 mL.
    2. 02Vinegar = 960 x 0.5 = 480 mL.
    3. 03Water = 960 x 0.5 = 480 mL.
    4. 04Salt = 960 x 0.03 = 29 g (about 2 tbsp pickling salt).
    5. 05Sugar = 0 g (dill pickles have no sugar).

    Frequently Asked Questions

    Can I use apple cider vinegar instead of white vinegar?

    Yes, as long as it has 5% acidity (check the label). Apple cider vinegar adds a mellower, slightly fruity flavor but may darken the brine and pickles slightly.

    Why use pickling salt instead of table salt?

    Pickling salt is pure sodium chloride with no anti-caking agents or iodine. Table salt anti-caking agents can cloud the brine, and iodine can darken the pickles.

    How long do quick pickles last?

    Quick pickles stored in the refrigerator last 2-3 months. They are best after 24-48 hours. For longer shelf life, process jars in a boiling water bath following tested canning recipes.
