Yield uses the Van Slyke formula with 93% fat recovery and casein at 78% of protein.

How the calculation works

How does the Van Slyke cheese yield formula work?

The Van Slyke formula estimates cheese yield from milk fat and casein. It credits 93% of the fat and most of the casein (the protein that binds into curd) to the cheese, applies a 1.09 factor for retained salts and minor solids, then divides by the dry-matter fraction (1 minus moisture) to give finished cheese weight.

Why does casein matter more than total protein?

Only casein coagulates into curd; the whey proteins largely drain off with the whey. The calculator estimates casein as roughly 78% of total protein, the standard share for EU bovine milk.

What moisture level should I use?

Gouda and Edam-style cheeses sit around 37 to 41% moisture. Harder cheeses such as aged Gouda or Parmesan are lower (30 to 35%); fresh cheeses are higher. Higher moisture means more finished weight per 100 kg of milk.

How accurate is this estimate?

Van Slyke is the industry-standard first approximation and is accurate to within a few percent for standard hard and semi-hard cheeses. Actual yield varies with make procedure, fat recovery, and standardisation.
