Parmesan is traditionally made from partially skimmed milk — the table uses each column's milk as-is; pick the "Partially skimmed" preset in the calculator for the classic parmesan number (~12.7 L/kg).
🔬 How the math works (no black box)
Rennet-set cheeses use the Van Slyke formula, the dairy industry's standard yield equation:
- fat% — fat in the milk (e.g. 3.7% for cow's milk).
- 0.93 — fat recovery: 93% of the milk's fat is kept in the curd (adjustable above).
- casein% − 0.1 — casein kept in the curd; ~0.1% is lost to the whey.
- × 1.09 — retained non-fat, non-casein solids (whey solids, minerals, salt).
- ÷ (1 − moisture) — the drier the cheese, the lower the yield. This single term explains why parmesan (31% moisture) needs far more milk than brie (51%).

❓ Frequently asked questions
How much milk does it take to make 1 kg of cheese?
It depends on the cheese style and the milk. Rough whole-cow's-milk rules of thumb for home cheesemaking: cheddar about 9.4 litres, low-moisture mozzarella about 7.9 litres, fresh mozzarella about 6.4 litres, gouda about 8.8 litres, brie about 7.3 litres, feta about 7 litres, paneer about 6.5 litres, and parmesan about 12.7 litres (it is traditionally made from partially skimmed milk). The quick-answer table above lists every style for cow, goat, sheep and buffalo milk.
How much cheese does a gallon of milk make?
One US gallon (3.79 L) of whole cow's milk weighs about 3.91 kg. At a typical cheddar yield of ~10.3%, that makes roughly 0.40 kg (0.89 lb) of cheddar. The same gallon makes about 0.59 kg of fresh mozzarella (higher moisture = higher yield) or about 0.66 kg of paneer (acid-set). Use the Milk to Cheese tab with imperial units for your exact style and milk.
What is the cheese yield formula?
The industry-standard formula is the Van Slyke formula: yield % = ((0.93 x fat% + (casein% - 0.1)) x 1.09) / (1 - moisture fraction). Fat% and casein% are the milk composition, 0.93 is the fraction of fat recovered in the curd, and moisture is the cheese's water content. This calculator shows every number plugged into the formula for your batch, so nothing is a black box.
How much goat milk do I need to make a pound of cheese?
Goat's milk is slightly richer than cow's milk, so you need a little less of it. For cheddar, about 9.0 litres of goat's milk makes 1 kg of cheese, so 1 lb (0.454 kg) needs about 4.1 litres — roughly 1.1 US gallons. Sheep and buffalo milk need noticeably less again because of their much higher fat and protein.
How much milk is needed for 1 kg of mozzarella?
About 7.9 litres of whole cow's milk for low-moisture mozzarella, or about 6.4 litres for fresh mozzarella (its higher water content raises the yield). Traditional mozzarella di bufala needs only about 3.9 litres of buffalo milk per kilo — the famous 4-to-1 ratio — because buffalo milk is far richer in fat and protein.
Why does parmesan need so much more milk than cheddar?
Two reasons, and the formula shows both. First, parmesan-family cheeses are traditionally made from partially skimmed milk (about 2.5% fat instead of 3.7%), so there is less fat to recover. Second, parmesan is very dry (about 31% moisture vs 37% for cheddar), and drier cheese means less water weight in the final wheel. Together that pushes it to roughly 12.7 litres of (skimmed) milk per kilo vs about 9.4 for cheddar.
What is fat recovery, and why can I adjust it?
Fat recovery is the share of the milk's fat that ends up in the cheese instead of the whey. The textbook default is 93%, and most hard cheeses land between 90 and 95% depending on the make procedure (cut size, stirring, cooking). Moving it from 90 to 95% changes cheddar yield by only about 0.3 percentage points — the slider lets you see that sensitivity for yourself.
Why do sheep and buffalo milk give so much more cheese?
Cheese is mostly recovered fat and casein plus retained water. Sheep's milk has about 6.5% fat and 4.3% casein vs about 3.7% and 2.6% for cow's milk; buffalo is similar. More solids in means more curd out — sheep's milk makes roughly 75% more cheddar per litre than cow's milk. The milk-type presets in this calculator use these real composition differences.
Can I use this calculator for cottage cheese or paneer?
Yes — switch to one of the acid-set styles. The Van Slyke formula only applies to rennet-set cheeses, so fresh acid-set cheeses (paneer, cottage, queso fresco, ricotta, cream cheese) use published whole-milk yield benchmarks instead, scaled by your milk's total solids. About 6.5 litres of cow's milk makes 1 kg of paneer; about 5.7 litres makes 1 kg of cottage cheese.
How much milk powder do I need to make 1 kg of cheese?
Reconstituted whole milk needs roughly 130 g of whole milk powder per litre (about 12.5% solids). So 1 kg of cheddar, needing about 9.4 litres of milk, takes roughly 1.2 kg of powder. The Cheese to Milk tab shows the powder equivalent for any style and milk type automatically.
How accurate is the Van Slyke formula?
For rennet-set cheeses it typically lands within 5-10% of real plant yields. Real batches vary with milk seasonality, exact fat and protein (get a milk analysis for the best numbers), make procedure, and salt and moisture targets. Treat the result as a planning estimate; commercial cheesemakers calibrate the fat-recovery factor against their own vats.
How much whey is left over after making cheese?
Most of the milk: roughly 85-90% of the milk's weight becomes whey. Making 1 kg of cheddar from 9.4 litres of milk leaves about 8.6 litres of whey. Sweet whey is usable for ricotta (about 5-6% of whey becomes ricotta), baking, or animal feed — the calculator shows the whey volume for every batch.
Does raw vs pasteurized milk change the yield?
Slightly. Pasteurization denatures a little whey protein and shifts calcium balance, which can soften the curd and trim yield by a small amount unless you add calcium chloride (the standard fix is about 1/4 tsp of diluted CaCl2 per gallon for pasteurized milk). Raw milk is not a yield strategy — it is a food-safety decision; follow local regulations.
How much milk do I need for a whole cheese wheel?
Multiply the per-kilo figure by the wheel or block weight. A 5 kg cheddar wheel needs about 47 litres of cow's milk; a 10 kg gouda wheel needs about 88 litres. Use the Cheese to Milk tab: enter the wheel weight, pick the style and milk, and it gives the milk volume, the powder equivalent, and the expected whey.
Is there a cheese yield calculator spreadsheet version?
The quick-answer table on this page is the spreadsheet equivalent: every style and milk type in one grid, with a copy-as-CSV button so you can paste it straight into Excel or Google Sheets. No download or sign-up needed, and everything runs in your browser.
How is this different from other cheese yield calculators?
Most existing calculators are static: one milk type, one direction, fixed numbers. This one computes both directions (milk to cheese and cheese to milk), covers four milk types with real composition data, shows the Van Slyke formula with your actual numbers plugged in, handles acid-set fresh cheeses with a separate honest method, and answers the common questions directly in a per-style table.
📚 Methodology & sources
- Formula: the Van Slyke yield equation as published in dairy-science literature (e.g. Kindstedt, P.S. — Cheese: Chemistry, Physics and Microbiology; Fox, P.F. et al.). The 93% fat-recovery default and the casein ≈ 78% of protein convention are the textbook standards.
- Benchmarks cross-checked against published yield tables: ~9–10 lb milk per 1 lb hard cheese (cheddar), ~4 L buffalo milk per 1 kg fresh mozzarella, ~13–16 kg milk per 1 kg parmesan from partially skimmed milk, paneer ~140–160 g per litre of cow's milk.
- Moisture values are typical composition-table figures (USDA FoodData Central style references) per cheese style; the calculator lets you override moisture for your exact make.
- Limitations: real vats vary ±5–10% with milk seasonality, exact composition, cut/stir/cook procedure, and salt targets. Pasteurized milk usually needs added calcium chloride for a firm curd. This tool is a planning estimate, not a process specification.
