Fermentation Brine Salt Calculator

Work out exactly how much salt you need for pickles, sauerkraut, kimchi or hot sauce. Choose the brine method (vegetables covered in salt water) or the mash / dry-salt method (salt mixed straight into shredded or chopped vegetables).

Typical salt percentages

FermentMethodCommon range
SauerkrautMash / dry salt2% to 2.5% of cabbage weight
Kimchi (salting cabbage)Brine soak, then rinsevaries; final about 2% to 3%
Cucumber pickles (sour)Brine3.5% to 5% of water
Mixed vegetables, carrots, beansBrine2% to 3.5% of water
Hot sauce, whole peppers in brineBrine3% to 5% of water
Hot sauce pepper mashMash / dry salt2% to 3% of pepper weight

These are common ranges from traditional practice, not rules. Lower salt ferments faster and softer; higher salt is slower and crunchier. Follow a trusted tested recipe for food safety.

Why weigh salt?

Salt crystals differ in size, so one tablespoon of fine table salt weighs roughly twice as much as one tablespoon of light flaky kosher salt. Measuring by volume can easily double or halve your salt. A kitchen scale in grams is the most reliable tool; the spoon amounts below are approximate conversions only.

The math

Brine (% of water): salt grams = water grams × % ÷ 100. One liter of water weighs about 1000 g.
Equilibrium brine: salt grams = (water grams + vegetable grams) × % ÷ 100. This gives the final salt level once salt spreads evenly through vegetables and liquid.
Mash: salt grams = vegetable grams × % ÷ 100.
