Monsieur Fromage
I made my first Cheddar on a Saturday in March, with recipe notes printed out and the confident energy of a man who had watched several YouTube videos. Three months later, I opened the wheel, cut a wedge, and tasted something that — and I'm being diplomatic — would not have been out of place in a school changing room.
The crumb was acrid. The finish was soapy. There was a stubborn, vegetal wrongness in the middle that no amount of toasted sourdough could rescue.
I blamed everything. The milk (innocent). The cultures (also innocent). My kitchen's ambient temperature (slightly guilty, not the main culprit). It took me a humbler second attempt — and a £90 pH meter I'd been resisting for months — to discover what had actually happened.
The autopsy
My first Cheddar was acidified about 0.2 pH units too far before I pressed it. It's the sort of sentence you read in a textbook and nod at, then cheerfully ignore, until you've tasted the consequences.
At a lower pH, the casein network pulls its calcium out too aggressively. The result is a crumb that's chalky, not creamy, and a flavour profile that skews bitter as aging proceeds — because the peptides proteolysis produces from a calcium-starved matrix are not the savoury ones you were hoping for. They are, to put it gently, the peptides that taste like laundry.
I was measuring time, not acid. The recipe said "press for an hour at X weight, then flip" and I followed those instructions as though they were the actual target. They weren't. The target was a pH reading between 5.1 and 5.2 at pressing. My curd had apparently skated past that point about twenty minutes before I started.
What I'd do differently now
- Buy the pH meter on day one, not on month three.
- Record pH at every gate — set, cut, drain, pre-press, pre-salt, out of press.
- Trust the number over the clock. Acidification speed depends on starter vigour, room temperature, milk's buffering capacity, and the phase of the moon.
- When something seems off, assume pH before you assume anything else.
If you're curious about why this matters, the long version lives here: pH and Acidity in Cheesemaking. It's the single most important piece of reading a new cheesemaker can do.
The wheel ended up in the compost. Second attempt, with a working meter, came out clean — still imperfect, but recognisable as a Cheddar rather than as laundry.
