How Is Coffee Processed? The Full Production Journey

Coffee goes through five real stages before it reaches your cup: growing, harvesting, processing, drying and milling, then roasting. Processing is the stage most drinkers know least about, and it's the one with the biggest single impact on flavour.

Here's what actually happens between the cherry and the green bean, and why it matters for what ends up in your bag.

Key Takeaways

Processing happens right after harvest: It's how the fruit gets removed from the bean, and the method used shapes the final flavour more than almost anything else in production.
Three methods dominate: Natural, washed, and honey processing each produce a genuinely different cup from the same cherry.
Instant coffee is processed differently again: It's brewed and dehydrated after roasting, not processed the same way as whole bean coffee.

What is the coffee production process, step by step?

Nicolas' Verdict: If you only remember one thing, remember this: processing happens before roasting, not after. Everything that determines a bean's base character is locked in long before it ever reaches our roastery.

The full journey runs: growing and harvesting the cherries, processing them to remove the fruit and reveal the bean, drying and milling to prepare them for export, then roasting at origin's destination roastery. Each stage adds or removes something from the final flavour, which is why two beans grown metres apart can taste completely different once processed differently.

How are coffee cherries harvested?

Hand-picking is the traditional method. Skilled pickers select only ripe cherries, which gives a more consistent, higher-quality result but costs significantly more in labour.

Mechanised harvesting strips cherries from the branch regardless of ripeness, using machinery. It's faster and cheaper, which is why it dominates large-scale production, but it pulls in some under-ripe and over-ripe fruit along with the good cherries.

What are the main coffee processing methods?

The processing method is where the biggest flavour decisions get made, and it happens well before roasting.

Comparing the three main processing methods

Method	How it works	Flavour result	Common regions
Natural (dry)	Cherries dried whole, beans absorb fruit sugars	Heavy body, fruity, sweet	Ethiopia, Brazil
Washed (wet)	Skin pulped off, mucilage fermented away	Cleaner, brighter, more acidic	Central America, East Africa
Honey	Some mucilage left on during drying	Between natural and washed	Costa Rica, El Salvador

Our own decaf coffee beans go through a washed process using the Colombian Mountain Water method, which is part of why they land closer to a clean, bright profile than a natural-processed decaf would.

What happens after processing?

Once processed, beans still need drying and milling before they're ready to export.

Drying removes remaining moisture, either by spreading cherries in the sun or using mechanical dryers. Sun-dried beans tend to come out fruitier and sweeter, while mechanically dried beans are more uniform.

Milling strips off the last parchment layer and sorts beans by size and density. This is the quality-control step that determines which beans are good enough to reach roasters like us.

Where is coffee grown?

Growing region shapes flavour just as much as processing does, altitude, climate, and soil all leave their mark on the cup. Our guide to coffee-growing regions and our piece on where coffee is grown cover this in full if you want to go deeper on origin specifically.

FAQs about how coffee is processed

1. What's the difference between washed and natural processed coffee?

Washed coffee has the fruit fermented and rinsed off before drying, giving a cleaner, brighter cup. Natural coffee dries with the fruit still on, giving a heavier, fruitier result.

2. Does processing method affect caffeine content?

No. Processing changes flavour, not caffeine content. Caffeine levels come down to bean type and roast, which our ultimate guide to caffeine content covers in full.

3. What is honey processed coffee?

It's a hybrid method where some of the fruit's mucilage stays on the bean during drying, landing somewhere between a washed coffee's clarity and a natural coffee's sweetness.

4. How is instant coffee made differently from regular coffee?

Instant coffee is brewed first, then dehydrated into soluble granules, either by spray-drying or freeze-drying. Regular coffee skips that step entirely, since you're brewing the actual ground bean yourself.

5. Is fair trade coffee processed differently?

Not necessarily. Fair trade refers to how farmers are paid and treated, not the processing method used. A fair trade coffee can be natural, washed, or honey processed like any other.

From cherry to cup

Processing is the step that turns a coffee cherry into something you'd recognise as a bean, and it's doing more work on your final flavour than most drinkers realise.

If ethical growing and processing matters to you as much as the flavour itself, our Fair Trade and Certified Organic ranges are grown and processed with exactly that in mind.
