Brine & Pickling

Weigh the salt right, every jar.

Start with a tested recipe, match its percentage basis, and calculate salt in grams. Choose vegetables plus water, water only, or dry salting.

The workflow

Pick the brine problem you need to solve now

Brine looks simple — salt and water — until two recipes call for tablespoons of different salts and end up tasting nothing alike. The calculators here weigh in grams first and translate back to tablespoons in a way that actually survives a brand switch.

01

Pick the salt percentage

Use the percentage and weight basis stated in your tested recipe. Different bases give different salt amounts.

02

Add vinegar (if pickling)

Follow a tested pickling recipe for food, vinegar and water proportions and the full preservation process.

03

Match the salt type

Diamond Crystal kosher and fine sea salt are not the same by volume — the tool corrects for this.

Common brine problems these tools solve

  • Mushy vegetables

    Salt, temperature and produce quality can affect texture. Follow the tested recipe; discard suspect batches.

  • Too salty

    Check the calculation basis and weigh salt. Equal spoonfuls of different salts can contain different weights.

  • White wrinkly film

    A description alone cannot reliably identify growth. Follow recipe spoilage guidance; do not taste a suspect batch.

  • Fuzzy coloured mould

    Toss it. Usually exposed veg above the brine. Use a fermentation weight on the next batch.

  • No bubbles after five days

    Bubbles alone do not establish progress or safety. Check the recipe and temperature; do not reduce its salt.

  • Cloudy brine

    Cloudiness can occur during fermentation, but appearance, smell and taste do not establish safety.

After the batch

Use the hub in this order

  1. 1

    First: match the percentage and calculation basis in your tested recipe.

  2. 2

    Second: weigh the salt in grams. Spoon conversions are approximate and depend on the salt type.

  3. 3

    Finally: follow the full recipe for submersion, temperature, completion checks and storage.

FAQ

Common brine & pickling questions

Should salt percentage include vegetables and water?
Follow the recipe’s stated basis. For a percentage of vegetables plus water, weigh both before adding salt. For a prepared water brine, use water weight alone. For dry salting, use vegetable weight. These methods cannot use the same percentage interchangeably.
What does 2% mean in this calculator?
It means 2 g salt per 100 g of the selected ingredients before salt is added. For example, 500 g vegetables plus 500 g water requires 20 g salt at 2% combined weight. Water-only mode gives 10 g for 500 g water at 2%. These are arithmetic examples, not recipe recommendations.
Does total weight include the jar or salt?
No. In vegetables-plus-water mode, total means the prepared vegetables, other recipe add-ins and added water, before adding salt. Exclude the container and fermentation weights. This recipe ratio differs from salt as a percentage of the final salted mixture.
What salt percentage should I use for fermenting?
Use the quantity and calculation basis from a research-based, tested recipe for that food. Keep its ingredient proportions, temperature, fermentation procedure and storage instructions. A percentage alone cannot establish that a ferment is safe.
How much salt does sauerkraut need?
The NCHFP tested sauerkraut recipe uses 3 tablespoons of canning or pickling salt for each batch of about 5 pounds of shredded cabbage. If the juice does not cover the cabbage, it adds boiled and cooled brine made with 1½ tablespoons of salt per quart of water. Follow the full recipe, including its temperatures and storage steps.
How much salt goes in fermented dill pickles?
The NCHFP fermented dill pickle recipe uses ½ cup salt dissolved in 8 cups of water and ¼ cup of 5% vinegar, poured over 4 pounds of 4-inch pickling cucumbers per gallon of container. Its salt, water and vinegar amounts work together, so keep them as written rather than swapping in a percentage.
Which salt should I use?
NCHFP recommends canning or pickling salt. Its guidance permits iodized or non-iodized table salt, but anti-caking ingredients can cloud brine. Spoon weights vary by salt type; the calculator’s spoon conversions are estimates. Do not substitute reduced-sodium salt in fermented pickle recipes.
How do I know fermentation is complete?
Follow your tested recipe’s completion checks and storage instructions. Time depends on the food and conditions. Taste, smell, bubbles or a calculated salt percentage alone do not establish safety. Do not taste a suspect batch.
