Pickle Brine Ratio Calculator
Mix a salt brine for fermented or quick pickles: enter your water volume and target salt percentage to get the exact grams and tablespoons.
How it works
Salt (g) = water (mL) × salt % ÷ 100 · Tablespoons ≈ salt g ÷ 15 (coarse kosher)
Pickle brines are defined as a salt percentage by weight of the water, and since water weighs about 1 g per millilitre the maths is direct. A 2–3% brine is the classic range for lacto-fermentation — salty enough to favour the good bacteria while the pickles sour — while 3.5–5% gives a saltier, crisper cure. Always weigh salt rather than measuring by spoon, because table, kosher and pickling salts differ in density.
Worked example
For a 3.5% fermentation brine in 1 litre of water: 1000 × 3.5 ÷ 100 = 35 g of salt, roughly 2.3 tablespoons of coarse kosher salt. Scale both up together for a bigger crock.
Frequently asked questions
What salt percentage should I use?
For fermented pickles, 2–3% by weight is standard. A quicker, saltier cure or firmer texture uses 3.5–5%. Below about 2% fermentation gets risky; above 6% it stalls the good bacteria.
Why weigh the salt instead of measuring spoons?
A tablespoon of fine table salt weighs far more than a tablespoon of flaky kosher salt, so a volume recipe can be off by 30% or more. Weighing to a percentage keeps every batch consistent.
Does this work for quick refrigerator pickles?
Yes for the salt component. Vinegar-based quick pickles also add acid and often sugar; use this to set the salt level, then add vinegar to taste.
