Processing Explainers

Natural Processing —
Fruit-Forward & Textural

When you see "natural" or "dry processed" on one of our bags, it means the whole cherry went to the drying bed intact — skin, fruit, seed, all of it. Done well, this produces bigger fruit, fuller body, and dessert-like sweetness while staying clean enough for daily drinking. Done carelessly, it's a mess. We only carry the ones that are worth it.

Step by Step

How Natural Processing Actually Works

Selective Picking

Natural processing punishes bad picking hard. Underripe cherries don't have enough sugar to develop properly and contribute green, grassy notes. Overripes go mushy and ferment unevenly. Only fully ripe, consistently red (or yellow, depending on variety) cherries go to the drying beds.

Sort & Float (Optional but Smart)

Some producers float-sort before drying — the same logic as washed: dense, ripe cherries sink; hollow or defective ones float and get skimmed. Not everyone does this step, but the ones who do tend to produce cleaner lots.

Whole-Cherry Drying — Weeks, Not Hours

Whole cherries are spread in thin, even layers on raised beds or patios. Workers rake and turn them multiple times a day to prevent mold, uneven drying, and fermentation pockets. This is the most labor-intensive part. Depending on altitude, humidity, and sun, drying takes 3–6 weeks — compared to days for parchment coffee.

Micro-Climate Management

Shade cloth, bed thickness, and airflow are all variables producers manage actively. Too thick a layer traps heat and moisture — mold risk. Too thin and drying is uneven. Good naturals are the product of producers who are obsessive about these details, not ones who just put cherries in the sun and hope.

Rest, Hull & Sort

Once dried to 10–12% moisture, the cherry rests in storage before milling. The dried fruit skin and pulp are then hulled off mechanically, the beans are sorted by density and screen size, and then defects are hand-sorted before export. A well-dried, well-hulled natural bean looks clean and green — not shrivelled or discoloured.

What goes wrong: Poorly managed naturals taste vinegary, boozy, or just muddy — sharp ferment character that doesn't sit well in the cup. These defects are permanent; no amount of roasting fixes bad processing. We taste through a lot of samples and pass on anything that isn't genuinely clean.

How It Tends to Taste

A well-processed natural coffee is genuinely one of the more exciting things in specialty coffee — the fruit character is unlike anything you get from washed lots. Here's the profile to expect when it's done right:

Fruit IntensityBlueberry, raspberry, strawberry jam, dried cherry — the fruit in a well-processed natural isn't subtle. It's the lead flavour, front of the cup, very much on purpose.
Full, Plush BodyThe sugars and oils from the fruit transfer to the seed during drying, producing a heavier, creamier mouthfeel than most washed coffees. Syrupy rather than tea-like.
Dessert SweetnessChocolate fudge, dark fruit jam, sometimes a winey or molasses note when the lot is pushed further. Lower brightness than washed — the sweetness is the story rather than the acidity.
Lower ClarityFlavour notes blend together more than in washed coffees — the impression is unified and lush rather than precise and separated. This isn't a flaw; it's a different aesthetic. We look for "big but clean," not muddy.

Brewing Natural Coffees

The body and sweetness of naturals reward brewing methods that preserve texture. Heavy-handed extraction amplifies ferment character — the goal is sweet and syrupy, not sharp. A slightly coarser grind and lower temperature than you'd use for a bright washed coffee usually gets you there.

MethodRatioGrindTempNotes
Pour-Over1:15–1:16Medium-coarse90–94°CGo slightly coarser than you would for a washed. Keeps the fruit sweet rather than sharp. Aim for 3:00–3:30 total.
Filter / Batch1:16Medium-coarse90–93°CNaturals can taste heavy in a batch brewer at regular ratios — dial back extraction slightly to keep it clean.
Espresso1:2–1:2.2Fine91–93°CWatch for fast blonding — naturals can look done before they are. Adjust grind fine in small steps. Syrupy is the target, not sharp or hollow.
Cold Brew1:8–1:10CoarseCold / room tempNaturals are exceptional cold brew. The chocolate-berry profile holds beautifully at low temperature — this is one of our strongest recommendations.
French Press1:14–1:15Coarse92–94°CThe extra body from immersion stacks well with the natural's existing body — rich, full, and sweet.

Natural Processing — Common Questions

Are naturals always funky or boozy?
They don't have to be — and when they're from us, they aren't. We look for naturals that are fruit-forward but clean: big berries and chocolate, without harsh ferment or vinegar notes. Over-fermentation is a processing defect, not a style. If it tastes like something went wrong at the farm, we don't carry it.
Why do good naturals cost more?
Labor, mostly. Workers are hand-raking and turning beds multiple times a day for 3–6 weeks. The sorting requirements are more demanding because every defect has more opportunity to damage the lot during drying. And the risk of losing a batch to mold or over-fermentation is higher than with washed lots, which producers price accordingly. We're happy to pay more when the care shows in the cup.
Do you roast naturals differently?
Yes, usually. We tend to give naturals a touch more development time to smooth out fruit intensity and draw out the chocolate notes. That might still read as "light" or "medium" on the bag — we adjust by coffee and by what the particular lot is telling us, not by a fixed rule based on processing alone.
Are naturals better for espresso or filter?
Both work well, but for different reasons. Filter lets you taste the fruit character cleanly. Espresso concentrates the body and sweetness into something almost dessert-like — a natural espresso pulled well is genuinely special. Cold brew is our honest recommendation if you want to show off what a natural can do: the chocolate-berry profile at cold temperature is hard to beat.
Is natural processing more environmentally sustainable than washed?
In terms of water use, yes — naturals use a fraction of the water that wet-milled washed coffees require, which matters a lot in water-stressed growing regions. The trade-off is more land and more labor time. There's no universally "greener" method — both have real advantages depending on the local context and how well-managed the operation is.
