Pickle Brine & Volume & Salt to Add
Brines mango
Enter your vegetable weight, a brine ratio and the brine strength to get the brine volume and the salt you need to preserve mango, lime, chilli or gherkin by salting and fermentation.
Mix the pickling brine
Next: dissolve 7.5 kg of salt in 75 L of water and pour over the vegetables so they stay fully submerged; keep them weighed down below the brine.
A 10%+ brine preserves by suppressing spoilage microbes while lactic fermentation develops; use non-iodised salt and clean, chlorine-free water.

The right salt keeps the pickle, the wrong amount spoils it
Salting and brining is the backbone of vegetable preservation: a strong enough brine pulls water from the produce and from spoilage microbes, while salt-tolerant lactic bacteria ferment and acidify the brine. Get the salt right and mango, lime, chilli or gherkin keep for months; get it wrong and the batch turns soft, slimy or moulds over. The concentration is the whole game.
This tool gives the brine volume and the salt you need from your vegetable weight, a covering ratio and the brine strength — so every batch hits the same reliable concentration instead of a guessed handful. Use it for salt pickles or lighter fermentation brines, then pair it with the Value Addition Profit and Dehydration Ratio tools to plan and price your preserved produce.

Frequently Asked Questions
How is the brine and salt calculated?+
Brine volume = vegetable weight × the volume ratio you choose (so the brine covers the produce), and salt = brine × the brine strength (concentration). For example 10 kg of vegetables at a 1.2 ratio gives about 12 litres of brine, and at 10% strength that's roughly 1.2 kg of salt. The tool does both steps for you.
What does salting and brining actually do?+
Salt draws water out of the vegetable and out of spoilage microbes, while a strong brine plus the absence of air suppresses harmful organisms. Salt-tolerant lactic acid bacteria then ferment the sugars into acid, lowering the pH. Together the salt and acidity preserve the vegetable and develop the tangy pickle flavour.
What brine strength should I use?+
It depends on the pickle. Long-keeping Indian salt pickles (mango, lime, chilli) often use 10% or more salt for shelf stability; lacto-fermented vegetables and gherkins typically use lighter brines around 3–6% that allow a livelier fermentation. Stronger brine keeps longer but tastes saltier — pick the strength for your product and climate.
Why does a strong brine suppress spoilage?+
High salt concentrations pull water out of microbial cells and create conditions most spoilage bacteria and moulds can't tolerate, while salt-tolerant lactic bacteria survive and acidify the brine. The combination of high salt, low oxygen and rising acidity is what makes brining a reliable, low-tech preservation method.
What is the volume ratio for?+
It sizes the brine to the vegetables so the produce stays fully submerged — exposed pieces spoil. A ratio above 1 means more brine than the vegetable weight, giving room to cover and weigh down the produce. Use a higher ratio for loosely packed or floating vegetables and a lower one for tightly packed jars.
What salt should I use for pickling?+
Use pure, non-iodised salt — pickling salt, kosher salt or plain sea salt. Iodine and anti-caking agents can darken the pickle or cloud the brine, and additives may inhibit the fermentation. Coarse or fine both work as long as it's additive-free; weigh it rather than measuring by volume for accuracy.
How do I keep the vegetables submerged?+
Pack them below the brine line and weigh them down with a clean plate, a brine-filled bag or a fermentation weight so no piece touches air. Anything above the brine can mould. Skim any surface scum, keep the vessel clean, and top up with fresh brine of the same strength if the level drops.
Which vegetables can I brine?+
Plenty — raw mango, lime, green and red chilli, gherkin and cucumber, cauliflower, carrot, turnip, garlic and more. Firm, fresh produce holds up best. Indian-style oil-and-spice pickles still rely on this salt step for safety; the calculator handles the brine and salt for any of them.
Can the brine be too weak or too strong?+
Yes. Too little salt risks spoilage and soft, off pickles; too much salt halts fermentation and makes the pickle harshly salty. The right strength for your product is the sweet spot. Use the calculator to hit a consistent concentration every batch rather than guessing by handfuls of salt.
Are the figures exact?+
The brine and salt are exact arithmetic for the ratio and strength you set, but the practical amount depends on how the produce packs, how much brine you need to cover it, and your recipe. Treat the result as your starting batch quantities and adjust the ratio to whatever fully submerges your vegetables.
