Cold milk is the most common culprit
When a home or artisan cheesemaker reports a set that never firmed, milk temperature is one of the first things to check — particularly in a cold room, an uninsulated pot, or a vat left uncovered during the set.
Too warm has its own problems
Pushing temperature up to force a faster set changes curd character and can work against the style you are aiming for. Temperature is a recipe parameter, not a throttle.
Practical control
- Measure at more than one depth before dosing.
- Cover the vat during the set.
- Watch ambient temperature — the same recipe behaves differently in January and July.
- Log the temperature you actually measured, not the one you intended.
