Brine to a salt target.

Choose the salt percentage you want in the cheese. Estimate the time, compare targets and refine the model with your own measured make.

What does 2% mean? 2 g salt in 100 g of cheese, including the salt. This is whole-cheese salt by weight, not brine strength or salt-in-moisture.

Your cheese

Target cheese salt % w/wTry 1.5% or 2%. Weight before brining kg Shape Diameter / width cm Thickness / height cm Block depth cmUsed only for rectangular blocks. Water before brining % w/wUse a measured or recipe-specific estimate. Salt already in cheese % w/w

Your brine & uptake rate

Brine salt concentration % w/wSalt ÷ total brine mass × 100. For example, 200 g salt + 800 g water makes 20% brine. Estimate method

Effective diffusion coefficient × 10⁻¹⁰ m²/s

2.21 is a published experimental Emmentaler coefficient. It is an illustrative starting point, not a validated value for your cheese or brining conditions.

Measured make

Use a make matching the dimensions, moisture, initial salt and brine entered above, at the same temperature and process conditions. Enter a representative whole-cheese salt measurement after the salt has redistributed—not a rind-only reading or the brine salinity.

The fitted coefficient absorbs your process effects. A single measured make calibrates one point; it does not validate the full curve.

Original idea and source inspiration: Complete Calculators’ Cheese Brining Time Calculator, credited to Natalie Reed. Tyrologia’s Python implementation independently estimates average salt uptake for a chosen cheese salt percentage; the source calculator uses a different planning method.

The reference coefficient comes from Guggisberg et al. (2025), Optimizing NaCl uptake in experimental Emmentaler cheese. Its experimental context does not validate this calculator for other cheeses.

How the calculation works

A constant-coefficient Fickian model combines the mean diffusion solutions for a disk and slab (round wheel), or three slabs (rectangular block). It assumes continuous contact with a large, constant-strength brine bath, unchanging geometry, uniform starting salt and a constant salt concentration at every exposed surface.

Equilibrium dissolved salt is approximated as water mass × brine salt fraction ÷ (1 − brine salt fraction). The model then solves for the time when salt ÷ (original non-salt cheese mass + salt) reaches your target. Cheese mass changes only by salt uptake in this calculation; water loss is not predicted.

Only round wheels and rectangular blocks are supported. Floating wheels, partial immersion, coatings, finite brine depletion and cheese-specific salt binding need a more detailed model or measurements. Halving all dimensions quarters the predicted time at the same composition and uptake coefficient.
