Brine Salt Calculator

Brine Salt Example: Cucumbers Under a 3.5% Brine

This example uses a hypothetical jar of cut cucumbers submerged in added water during a warm week, to show how the same salt weight changes shape depending on which salt is in the cupboard.

Fermentation counter with a jar of brined cucumbers, a cabbage ferment jar, a kitchen scale holding a bowl of salt, a halved cabbage, and measuring spoons.

This example uses a hypothetical scenario to show how the calculator works. It is a curated example page, not a saved user result or a claim about a real person.

Inputs used in the example

InputExample value
What you are saltingCut, under added water
Vegetable weight900 g
Water added1100 g
Target salt strength3.5%
Salt you will measure withMorton coarse kosher salt
Room it will ferment inWarm, over 24 C / 75 F

Output interpretation

The percentage applies to the cucumbers and the water together, so 3.5% of 2000 g is 70 g of salt.

That single 70 g is about 4 tbsp plus 2 1/2 tsp of Morton coarse kosher, about 3 tbsp plus 2 3/4 tsp of fine table salt, and about 8 tbsp plus 1 tsp of Diamond Crystal kosher. Same salt weight, three very different scoops.

A warm room is the reason this example sits at the higher end of the usual range rather than at 2%.

What to check next

  • Taste daily in a warm room and move the jar somewhere cooler if it races.
  • Keep every piece under the brine, and discard the batch if anything fuzzy or off-smelling appears rather than salting it further.
  • If you top up the jar later, mix the top-up brine at the same percentage instead of adding plain water.
