The cup

Lemongrass. Clean, citric, almost herbal. Then figs. Dried, dense. A quiet sweetness that sits underneath. Grapefruit on the finish, not bitter, more like the pith of a pink grapefruit eaten in the morning.

Geisha is a cultivar that rewards attention. Rushed, it gives less than a supermarket blend. Brewed carefully at 1:16, just off the boil, a slow draw. It gives almost too much.

Grown by Nestor Lasso at El Diviso, third generation on the farm. Twenty-four hours of anaerobic fermentation. Thermal shock at sixty-five degrees. Then dehumidified drying. The Lasso family standardised the protocol over many harvests.

The story

Eighty thousand trees across eighteen hectares of southern Colombia. Geisha is a small fraction of them. A cultivar the Lasso family chose to grow despite the difficulty, because the cup repays the patience.

Nestor's grandfather, José Uribe, planted the original El Diviso trees. Nestor himself is twenty-four. He works the farm with his family.

A standing arrangement

Arriving on a rhythm.

For drinkers who already know which coffee they want. Same coffee, same bag, the same single-origin standard. This is about not running out.

Pause, skip, or end whenever you like. A single email does it.

01Why this one

Why it is on the shelf.

We buy this lot from Finca El Diviso, Huila. Grown at 1,700 to 1,850 m. One farm, one lot, one harvest, bought because the cup earned it and not because it was easy to source.

02Why organic

What it means by the time it reaches you.

Most coffee is grown on a schedule of sprays. Fertiliser, herbicide, fungicide, applied to a plant that fruits in some of the wettest country on earth. It works, and it leaves a farm that needs a little more of it every season.

Organic is the decision not to. Compost in place of synthetic nitrogen, shade canopy in place of a cleared field, three years of it before the word may be used at all. It costs the farmer more and yields less, which is why so little coffee is grown this way.

You taste the consequence rather than the practice. Under shade the cherries ripen slowly and unevenly, so they are picked in passes rather than stripped in one. Nothing was added to the field to carry a thin harvest. What is in the cup, the tree made.

And there is the part that matters at seven in the morning, before anyone has thought about agriculture. You are not wondering. It is the same instinct as turning the olive oil around to read the back, applied to the one thing you drink every single day.

03What we measured

Screened before it is roasted.

A certificate records what a farm agreed not to use. It cannot tell you what is in the bag you are holding. So we send green beans to an independent laboratory and ask that question separately, against 952 pesticide and herbicide residues alongside ochratoxin A and the four aflatoxins.

This lot, batch 0526-CGS, is in that programme, and its report is not published yet. Three of our eight coffees have theirs online today and the rest follow as each batch clears. We would rather show you an empty space here than borrow someone else's result.

Mycotoxins are the reason this is a separate question at all. They form after harvest, in humid transit and storage, which is a stage no farming certificate covers.

Before you buy

The questions we would ask.

Is it worth RM55?
A 100g bag pours roughly six cups, which puts a considered morning at a little over the price of a takeaway flat white, made at home in your own time. You are also paying for things that cost us money and are easy to skip: single-origin buying rather than blending, roasting to order rather than to stock, and laboratory screening on the green bean.
Is this one for me?
Finca El Diviso, Huila. A single Gesha cultivar from the Lasso family farm, at 1,700 to 1,850 metres. If you already drink filter coffee black and notice the difference between origins, yes. If you take it with milk and sugar and want something dependable rather than distinctive, one of the chocolatier origins will suit you better, and we would rather point you there than sell you the wrong bag.
Can I trust what you claim?
By publishing the parts that do not flatter us. This coffee is certified organic, audited annually by an accredited body. Every batch goes to an independent laboratory accredited to ISO/IEC 17025 before roasting, and the reports are published whole rather than summarised into a claim. Where a lot has not been screened yet, we leave the space empty rather than borrow another result.
How long does a bag last?
Roughly six cups from 100g, so a fortnight for one person drinking a cup most mornings, or about a week for two. It is a deliberately small bag. Coffee is at its best in the first weeks after roasting, and we would rather you finished it while it is still worth drinking than kept it going stale.
How should I brew this one?
We would start with filter, v60 or chemex. or immersion, aeropress. Roasted light, so it is forgiving of a slightly coarse grind and rewards water just off the boil. Whole bean, ground at home if you can, because coffee begins losing its aromatics within minutes of grinding.
What if I do not enjoy it?
Write to us. If the bag is faulty, unfresh, or not what we promised, we replace it or refund it. Taste is personal, so if a coffee simply did not suit you, tell us what you thought and we will point you at the one that will. It helps us think about what to carry next.
