The cheesemaker cut by feel, then wrote down why

Times down the left, 05:30 to 07:45. Two columns beside them, both falling — pH and temperature. Against the last row, circled in green: CUT. Underneath, in a fast hand: slow set, gave it 20 more.

The cheesemaker didn't cut at a number. They cut when the curd looked right, and the number is what they'll be judged on.

What is the sheet actually recording?

A decision, not a process.

Milk doesn't turn to cheese on a schedule — it's a biological process running at whatever pace the bacteria and the day's milk allow, and the maker's real skill is reading the curd itself: how it breaks off a spoon, how it holds a clean edge when cut. The pH and temperature columns are recorded alongside that judgement so the decision has evidence attached to it afterward, when nobody else in the room can taste what the maker tasted at 07:45.

Why does the pH fall the way it does?

Because it's tracking the bacteria doing the actual work.

The starter culture converts lactose to lactic acid, and the acid is what pH measures — so a column falling steadily from 6.51 to 5.66 is a live graph of fermentation happening in real time, one reading at a time. A curve that falls too fast or stalls tells the maker something's wrong with the culture or the milk before the cheese itself shows any sign of it.

Why write "gave it 20 more" in the margin?

Because the sheet without it is a lie about how the day went.

The set didn't run to plan — it was slow, so the maker held it twenty minutes longer than the schedule called for, and that decision changes the cheese: a longer set draws more moisture out of the curd before cutting, which means a firmer, drier result than the same recipe run to time. The note is the only place that fact survives. Without it, next month's maker reads a set of numbers that don't match what they'll see in the vat and has no idea why.

What makes a good make sheet?

One somebody else could pick up partway through the make and understand.

The times, both columns, the cut point marked clearly, and a margin note whenever the day departed from the plan — which is most days, because milk varies and weather affects a room even indoors. A sheet with no margin notes at all is usually one nobody trusted enough to write on honestly. In that sense it's making the same promise as a bar's spec card: that the same inputs, followed the same way, get you the same result.

Does the sheet belong to a particular dairy?

The format doesn't. A specific dairy's actual recipe might.

Times, pH curves and cut points are a record of a process, not a possession — nobody owns the fact that lactic acid lowers pH. A named creamery's exact recipe and cheese name are a different matter and are theirs to licence if putting a real one on a shirt is the point; the invented make sheet here sidesteps that and lets the wearer print their own day rather than someone else's.

Does this apply beyond cheese?

Anywhere a live process gets judged by feel and recorded as numbers afterward.

A brewer's OG and FG readings do the same job for fermentation from the other end — recording what happened rather than what was decided in the moment. A baker's proofing log and a winemaker's fermentation curve are both variations on the same idea: the craft is the judgement, the sheet is the alibi.

Does it print well?

Yes — a ruled table with two falling columns is a strong, legible shape.

Keep the numerals crisp and dark against bone or cream; the pH column carries the story of the piece, so it should read clearly enough to follow top to bottom at a glance. Reserve the green for the single circled CUT — one hit of colour on the decision itself, nowhere else.

How do I get one made?

Describe your sheet at JustOG — the times, how the columns should move, and what the margin note says. Pick a direction, drag the crop frame, see it composited on the real garment, and it's made to order and shipped.
