Three numbers and a taste note
A dial-in card is the whole craft on one piece of paper — dose, yield, time, and what it tasted like. It changes every morning, which is exactly why it's worth printing one.
DOSE 18 · YIELD 36 · TIME 27, and underneath, in someone's handwriting: tastes like dark
chocolate, toffee, orange zest.
That's an espresso recipe. It was true this morning and it may not be true tomorrow, which is the most interesting thing about it.
Why is a dial-in card the right artefact?
Because it's a craft that has to be re-derived daily and written down every time.
Beans change as they age. Humidity moves. The grinder drifts. So every morning somebody pulls shots, adjusts, tastes and writes the numbers on a card by the machine — and that card is the only record that the work happened at all.
It's the same shape as a nurse's observation chart: a grid somebody filled in by hand, which is evidence of attention rather than a symbol of a job.
Why do the numbers work on a chest?
Because they're a complete sentence to about four hundred thousand people and gibberish to everybody else.
18 / 36 / 27 is instantly parseable by anyone who has worked a bar — a ratio, a time, and an
implied grind setting. To everyone else it's three numbers in boxes, which reads as a nice
technical graphic.
Numbers are legible to everyone and meaningful to almost nobody, and this is one of the purest examples of it.
What's the handwriting doing?
Making it a person's card rather than a specification.
The printed grid is the form; the taste note is what somebody wrote in it. That split — printed structure, handwritten field — is what makes the design read as a used object.
Same device as a recipe in somebody's own hand, and it's why the note should be scrawled rather than set.
What should the taste note say?
Something honest, including the unflattering versions.
Dark chocolate, toffee, orange zest is a good day. So is sour, grind finer, ashy, nobody noticed, third attempt. The failures are funnier and they're the more accurate record of what the job is like.
The register wants dryness. A note that reads like marketing copy turns the card into a menu.
Can I put the roaster or the café on it?
Your own café, yes. A roaster's name and their coffee's branding are theirs.
The interesting version doesn't need either: a dial-in card with no house name is universal to the trade, and one with your own name on it becomes a staff shirt people will actually wear — small mark, one-colour version, off to one side.
Is this only for baristas?
It's for anyone who dials something in, which is more trades than it sounds.
Bakers have hydration percentages and proof times. Brewers have gravity readings. Photographers have exposure triangles. Anyone whose work is a set of parameters re-tuned daily has an equivalent card, and none of them have merchandise.
The format is the same: printed grid, three numbers, one handwritten line.
Does it print well?
Very. It's type in a grid with generous spacing.
The numbers are large by design, which is most of the print sorted. The handwritten note is the element to watch — script at small size loses its character on cloth, so it wants to be comfortably readable at conversational distance rather than a whisper.
Big numbers, legible note, nothing else. It's one of the simplest designs in this section and one of the most specific.
How do I get one made?
Give the numbers at JustOG — your actual recipe — and the taste note in your own words. Pick a direction, drag the crop frame, see it composited on the real garment, and it's made to order and shipped.
Designs other people have published are in the shop.
Tomorrow it'll be 17.5 and 42. That's why somebody writes it down.
