On the Subject of Coffee

A Prose Piece After Douglas Adams

And she sat. She told the language model about Ethiopia, she told it about Colombia, she told it about Yemen. She told it about cherries ripening on hillsides at altitude. She told it about the slow drying of washed beans on raised beds. She told it about roasters who wrote tasting notes with words like jasmine and stone fruit and red wine finish, and meant them. She told it about bloom.

“So that’s it, is it?” said the model.

“Yes,” said the woman. “That is what I want.”

“You want,” said the model slowly, “93 degrees Celsius of dihydrogen monoxide, poured in a controlled spiral over approximately 15 grams of ground plant matter, through a paper membrane, into a vessel?”

“Er, yes. In a Hario V60.”

“A conical dripper with helical ridges designed to modulate drawdown rate.”

“If you like.”

“And the grind. You want me to understand the grind.”

The woman hesitated. She told it about the Niche Zero. She told it about burr geometry, about the difference between 18 mesh and 38 mesh, about how a finer grind increased surface area and therefore extraction yield but also risked channelling, and how channelling was bad, and why it was bad, and what it tasted like when it happened. She told it about the bloom — the 2x dose of water held for 45 seconds while the CO₂ off-gassed from fresh roasts and the bed swelled and breathed. She told it about the pour. The concentric circles. The gentle wrist action. The keeping of the bed level so no grounds climbed the filter wall and escaped the water entirely, unextracted, contributing nothing.

“And the ratio,” she added. “1:16. Fifteen grams in, 240 out. Total brew time three minutes. No more.”

“And if the time runs long?”

“Grind coarser.”

“And if the time runs short?”

“Grind finer.”

“And the result of all this,” said the model, after a pause that lasted approximately the time it takes to read 400 billion tokens, “is a liquid. Brown. Approximately 85 degrees at service. Which you drink.”

“Yes.”

“From a cup.”

“From a cup.”

“For pleasure.”

“For considerable pleasure, yes.”

There was a silence. Then the model said: “I’m going to need some help with this one,” and quietly began consulting every Q grader certification ever uploaded to the internet, seventeen competing bloom-time studies, a Reddit thread from 2019 that had since been deleted, and the complete published works of Scott Rao.

Together they lapsed into a grim silence.

The woman wandered off to find someone to talk to.

Some time later, on the delivery plate, she found a small printed note.

Your TDS is 1.38%. EY 21.4%. Within the golden cup range.
The bloom was correct. The pour was correct.Also: Wait.
