We had read about wet-hulling for years and understood none of it until we were standing in it, in the rain, watching parchment go grey-green under a blue net.

The nursery came first — tunnels of seedlings, two years from anything drinkable. Then the rows, then the tanks, then the patio, then a mill that sounded like a small factory because that is what it is. In ten days we saw the same lot at five stages of its life, which is not something you can do on a buying trip.

What we took away was mostly a set of questions. Why turn by hand four times a day rather than three. What the shade net actually does. How you decide a lot is finished. We asked all of them badly, in two languages, and got answers we are still thinking about.

She ran the nursery, the rows, the tanks and the warehouse, and walked us through all four in an afternoon.

Everything we know about this coffee came out of that walk. We have it on video and we have not transcribed it yet, which is why there is no quotation on this page.

What we noticed

Ours, not the farm’s claims

Turned by hand

Four times a day, by whoever was nearest. No machine anywhere in the drying stage.

The bag was wrong

Nothing we tasted on the table resembled the notes printed on Sumatran bags at home.

Signage as record

A yellow board in the rows reading RED CATURRA · NOVEMBER 2024 — the only written provenance on site.
