Brine Salt Concentration Calculator

Calculate the exact amount of salt needed for any brine percentage.
Perfect for lacto-fermentation of vegetables, pickles, kimchi, sauerkraut, and more.

Salt Needed

Brine Salt Concentration

Salt Weight = (Water Weight × Brine %) ÷ (100 − Brine %)

For a 2% brine using 1000g of water: Salt = (1000 × 2) ÷ 98 ≈ 20.4 grams

Recommended concentrations for different ferments:

Ferment Salt % Notes
Sauerkraut / Kimchi 2% Applied to shredded vegetables by weight
Cucumber pickles 3–5% Keeps cucumbers crunchy
Fermented hot sauce 2–3%
Fermented garlic 2–3%
Olives 8–10% Higher salt for firm texture
Curing / preservation 10%+ Not for eating as brine

Use non-iodized salt only — iodine inhibits beneficial bacteria.
