The washing station at Kanzu sits on a hill above the lake, surrounded by neat rows of fermentation tanks and a drying field of raised beds that, at six in the morning, are still blue with dew. A group of women in patterned kitenge is already at work on the beds, hand-sorting parchment coffee by color and density under a sky that has not yet decided what to do.
Immaculée Umutesi is the one with the ledger. She is the station manager, the cooperative’s vice-president, and, since 2008, the person whose signature has to appear on every export contract leaving the facility. She is fifty-one. She runs the station with a combination of enormous warmth and absolutely no tolerance for approximation.
“We started with forty-two women,” she says, not looking up from the ledger. “One borrowed depulper. A promise to each other. Everything else is arithmetic.”
Arithmetic, and its opposite
The women who founded Kanzu did so in the early 2000s, in the long shadow of the genocide that had, in 1994, killed or displaced nearly everyone in the region. Many were widows. Many had returned to farms that had no workers, no infrastructure, and, in some cases, no clear legal ownership. Coffee was one of the few cash crops that still had an export market. It was also, at the time, being bought from small farmers at prices that barely covered the cost of picking.
What the cooperative did was, at first, unremarkable: they pooled their cherries, bought a depulper, and sold parchment coffee collectively. What happened next was not unremarkable. Within five years they had a full washing station, a quality manager trained in Kigali, and a direct-trade relationship with a roaster in Portland, Oregon, who paid a premium that they used to buy a truck. The truck allowed them to collect cherries from farms higher up the hill that had, until then, been too remote to reach during the short daily window in which a ripe cherry can be depulped without damaging the bean.
The premium is now significantly larger. The truck is newer. There are fourteen hundred members. The coffee, every year, gets a little better, which is, Immaculée says, the only thing that matters.
The discipline of the double soak
Rwandan washed coffee has a particular character — clean, bright, with a tea-like delicacy and notes of red fruit — that comes from a processing method that is, by global standards, almost pathologically demanding. The cherries are pulped within six hours of arrival. They ferment underwater for sixteen to eighteen hours. They are washed, graded through grading channels, and then, crucially, soaked a second time in clean water for another twelve to twenty-four hours before being moved to the drying beds.
The double soak removes almost all of the residual mucilage. It produces a cup that is extraordinarily transparent. It also means that any flaw in the coffee — an under-ripe cherry, an insect bite, a fermentation off-note — is ruthlessly exposed. The margin for error is essentially zero.
This is why Kanzu hand-sorts everything twice, once at cherry and once at parchment, and why the raised beds are manned, literally, by hand from dawn until dusk during the drying period. The coffee at the end of this process is not forgiving. It is truthful. That is the trade.
A different kind of ledger
In the office above the station, Immaculée keeps two sets of books. The first is the export ledger, with contract numbers, weights, prices, and buyer codes. The second is a green cloth-bound notebook in which she records, by hand, the names of every member of the cooperative, the size of their plot, the number of trees they manage, the amount of cherry they delivered last season, and — in a column that she added herself, five years ago — what the premium they received that year was spent on.
The entries are specific. Primary school fees for two children. Roof repair. Replacement of depulper motor. Funeral expenses for mother-in-law. Savings toward calf. The book is, as a working document, an accounting of where the value of the coffee actually goes once it leaves the hill.
“This one,” she says, putting her finger on a line. “Marie-Claire. She bought a bicycle last year. This year her daughter rides it to secondary school. That is the coffee.”
She closes the book. Outside, on the drying beds, the parchment has turned the color of old ivory in the morning sun. Somewhere down the hill, the first depulper of the day has started up, and the faint, green-apple smell of fresh mucilage is beginning to rise over the station.
