After origin and roast level, processing method is one of the biggest — and most overlooked — factors shaping how a coffee tastes. Two coffees grown metres apart on the same farm can taste completely different depending on whether they're washed or naturally processed. This guide explains what each method actually involves, how they change flavour, and how to spot which one you're buying.

The quick answer

Processing is how the fruit (the "cherry") is removed from the coffee bean after picking. Washed coffee has the fruit removed before drying, producing a cleaner, brighter, more acidic cup that shows off origin character clearly. Natural processed coffee is dried inside the whole fruit, producing a heavier, sweeter, fruitier and more fermented-tasting cup. Neither is better — they're different styles that suit different taste preferences.

What "Processing" Actually Means

A coffee cherry is a small fruit with a seed (the coffee bean) inside, surrounded by pulp, a sticky layer called mucilage, and a protective skin. Before a bean can be roasted, all of that fruit needs to be removed and the bean dried down to a stable moisture level. How and when that fruit is removed — the processing method — has a huge influence on the final cup, because the bean absorbs flavour compounds from the fruit around it the longer it stays in contact with it.

Washed (Wet) Processing Explained

In washed processing, the skin and pulp are removed from the cherry mechanically shortly after picking, and the remaining sticky mucilage is then fermented briefly and washed off with water before the bean is dried. Because the bean spends very little time in contact with the fruit, washed coffees tend to taste clean, crisp and bright, letting the origin's own natural characteristics — its acidity, sweetness and varietal character — come through clearly without being layered with extra fruitiness. Our Colombian, Guatemalan, Peruvian and Ugandan single origins are all fully washed.

Natural (Dry) Processing Explained

In natural processing, the whole cherry is dried in the sun with the fruit still intact around the bean, often for several weeks, before the dried fruit is finally removed. Because the bean stays in prolonged contact with the sugary fruit as it dries, it absorbs much more of that fruit's character, producing a heavier body and pronounced fruity, sometimes wine-like or fermented sweetness. Our Amici House Roast, a Brazilian coffee from the Fazenda El Dorado estate, uses honey and natural processing, giving it its rich hazelnut, mango and milk chocolate character.

What's "Honey Processing"?

Honey processing sits between washed and natural. The skin is removed like a washed coffee, but some or all of the sticky mucilage is left on the bean during drying rather than washed off, so the bean picks up some of the sweetness and body of a natural process without going as far. Honey-processed coffees typically taste sweeter and fuller-bodied than washed coffee, without the more intense fermented fruitiness of a fully natural process — a useful middle ground, and part of what shapes the profile of our Amici House Roast.

How Processing Changes What You Taste

Washed coffees tend to taste clean, crisp and bright, with clear citrus, floral or tea-like notes and a lighter body — a good showcase for a specific origin's natural character. Natural coffees tend to taste heavier, sweeter and more fruit-forward, often with notes like berry, tropical fruit or wine, and a fuller, syrupy body. Honey processed coffees sit in between, usually landing on sweeter, rounder notes like caramel or stone fruit with a fuller body than a washed coffee but less intensity than a fully natural one.

Why Different Regions Favour Different Processing Methods

Climate has historically driven which processing method a region uses, more than tradition alone. Areas with reliable dry seasons and lower humidity, such as parts of Brazil and Ethiopia, are well suited to natural processing, since the cherries can dry slowly and evenly in the sun without rotting. Regions with more rainfall or humidity, common across much of Central and South America, tend to favour washed processing, which removes the fruit early and reduces the risk of spoilage during drying. That's part of why Amici's washed single origins come from Colombia, Guatemala, Peru and Uganda, while our naturally processed house roast comes from Brazil — the method often reflects what the local climate makes practical, as much as a deliberate flavour choice.

Common Misunderstandings About Processing

A common myth is that natural processing is a lower-effort or lower-quality shortcut — in reality, it requires very careful, attentive drying over several weeks to avoid mould or uneven fermentation, and a well-executed natural process is every bit as skilled as a well-executed washed one. Another myth is that processing method is the same as roast level; they're entirely separate variables; a coffee can be washed or natural at any roast level. Finally, processing method isn't a reliable indicator of caffeine content — it changes flavour and body, not strength.

How to Choose Based on Processing Method

If you enjoy a clean, bright, origin-driven cup — particularly through a pour-over or filter — a washed coffee is usually the safer choice. If you enjoy something heavier, sweeter and more adventurous, with pronounced fruit character, a natural or honey-processed coffee is worth seeking out, especially brewed through a cafetière or as espresso where the fuller body comes through well. Checking the processing method listed on the bag, alongside the tasting notes, tells you far more than the origin name alone.

Our Amici Recommendation

To try a natural process, our Amici House Roast is honey and natural processed, from the Fazenda El Dorado estate in Brazil, with rich hazelnut, mango and milk chocolate notes and an 85/100 cupping score. To try a washed process, our Guatemalan Single Origin from Huehuetenango is fully washed, offering a clean, vibrant cup with maple, caramel and honey sweetness.

Frequently Asked Questions

Is washed or natural processed coffee better?
Neither — they're different styles. Washed coffee tastes cleaner and brighter; natural coffee tastes heavier and fruitier. It comes down to personal taste.

Does processing method affect caffeine content?
No. Processing changes flavour and body, not caffeine strength.

Is natural processed coffee always more expensive?
Not necessarily, though it can be more labour-intensive to do well, which sometimes affects price. Cost varies more by origin, altitude and rarity than by processing method alone.

What does "honey processed" mean exactly?
It means some or all of the sticky mucilage is left on the bean during drying, giving a sweetness and body between washed and natural coffee.

Can I tell processing method just by looking at the beans?
Not reliably. Processing method is usually listed on the bag; looking at the beans alone isn't a dependable way to identify it.

The Bottom Line

Washed, honey and natural processing each bring out a different side of the same bean — clean and bright, sweet and rounded, or heavy and fruity. Trying one of each is the best way to discover which style you actually prefer.
