Why Processing Method Changes Everything

You can take two coffee beans from the same tree, on the same farm, at the same altitude — and produce two completely different cups. The difference? How the coffee is processed after harvest.

Processing is the step between picking the ripe coffee cherry and producing the green bean that gets roasted. It determines how much of the fruit's natural sugars, acids, and flavour compounds transfer into the bean. It is one of the most powerful tools a coffee producer has — and one of the least understood by coffee drinkers.

At Kafe de Flores, we use multiple processing methods across our range of Manggarai, Flores coffees. This guide explains each method, what it does to the cup, and which of our coffees to try if you want to experience it.

The Coffee Cherry: Where It All Starts

Before we get into processing, it helps to understand what a coffee cherry is. The coffee bean is actually the seed inside a fruit — the coffee cherry. Each cherry has several layers: the outer skin, a layer of pulp, a sticky mucilage layer, a parchment layer, and finally the green bean at the centre.

Processing is essentially about deciding which of these layers to remove, when, and how — and how long the bean spends in contact with the fruit during drying. Each approach produces a fundamentally different flavour profile.

Washed Process (Wet Process)

What happens:

The skin and all of the pulp and mucilage are removed from the cherry immediately after picking, usually using water and mechanical depulping. The clean bean is then dried on raised beds or patios.

What it tastes like:

Washed coffees are the most "transparent" — they showcase the pure character of the bean and its terroir with minimal interference from the fruit. Expect high clarity, bright acidity, and clean, precise flavours. Floral, citrus, and tea-like notes are common. The body tends to be lighter and more delicate.

Best for:

Coffee drinkers who appreciate clarity, brightness, and terroir expression. Excellent for V60 and pour over brewing methods that highlight acidity and delicacy.

From Kafe de Flores:

Arabica UWU — our washed Arabica from Uwu Village, Manggarai. Clean, bright, and expressive — a textbook example of what high-altitude washed Arabica from volcanic Indonesian soil can achieve.

Honey Process

What happens:

The skin is removed but some or all of the sticky mucilage is left on the bean during drying. The amount of mucilage retained determines the "colour" of the honey process — Yellow Honey (least mucilage), Red Honey, and Black Honey (most mucilage). The bean dries slowly with this sticky layer intact, absorbing sugars and flavour compounds from the fruit.

What it tastes like:

Honey process coffees sit between washed and natural. They have more body and sweetness than washed coffees, but more clarity and structure than naturals. Stone fruit, caramel, and floral notes are common. The mouthfeel is smooth and round.

Best for:

Coffee drinkers who want complexity and sweetness without the intense fruit-forward character of natural process. Versatile across brewing methods — excellent for V60, Chemex, and Aeropress.

From Kafe de Flores:

• Grand Cru Gulang — Yellow Caturra, Honey Process. Our flagship. Stone fruit, florals, and exceptional clarity from Gulang Village at 1,400m.
• Farmhouse Heritage — Kartika, Red Honey. Tropical fruits, pomelo, and pear from Mbohang Village.
• Estate Heritage Mbohang — Kartika, Black Honey. The richest honey process in our range — black tea, orange, and raisin with a luscious, heavy mouthfeel.

Natural Process (Dry Process)

What happens:

The whole cherry — skin, pulp, mucilage, and all — is dried in the sun with the bean still inside. This can take several weeks. During this time, the bean absorbs an enormous amount of flavour from the surrounding fruit as it ferments and dries.

What it tastes like:

Natural process coffees are the most fruit-forward and full-bodied of the three methods. Expect intense sweetness, low acidity, and bold fruit notes — often blueberry, tropical fruit, dark chocolate, or wine-like fermentation character. The body is heavy and the finish is long.

Best for:

Coffee drinkers who love bold, sweet, fruit-forward cups. Excellent for French Press, cold brew, and espresso — methods that highlight body and sweetness.

From Kafe de Flores:

• Harmony Blend UWU — 50% Arabica, 50% Robusta, Natural. Orange, chocolate, and brown sugar from Uwu Village.
• Village Blend UWU — 70% Arabica, 30% Robusta, Natural. Orange, chocolate, and black tea — the ideal everyday natural process blend.
• Arabica UWU (Natural) — 100% Arabica, Natural. Bright and fruit-forward with excellent sweetness.

Anaerobic Natural: The Experimental Method

Beyond the three classic methods, there is a newer experimental approach gaining popularity in specialty coffee: anaerobic natural processing. The cherries are placed in sealed, oxygen-free tanks where they ferment under controlled conditions before being dried naturally. This produces highly complex, unique flavour compounds that cannot be achieved through conventional processing.

From Kafe de Flores: Funky Fruity — Kartika, Anaerobic Natural. Our most adventurous coffee. Tropical fruit, fermentation complexity, and a bold, unmistakable character. Not for the faint-hearted — but unforgettable for those who love it.

Which Processing Method Is Right for You?

The honest answer is: try all three. Processing method is one of the most exciting variables in specialty coffee, and your preference will depend on your palate, your brewing method, and your mood.

But if you need a starting point:

• If you love bright, clean, precise coffee — start with Washed. Try Arabica UWU.
• If you love sweetness and complexity without intensity — start with Honey. Try Grand Cru Gulang.
• If you love bold, fruit-forward, full-bodied coffee — start with Natural. Try Harmony Blend UWU.
• If you love adventure and intensity — go straight to Anaerobic Natural. Try Funky Fruity.

All of our coffees from Manggarai, Flores are available in Whole Bean, Fine, Medium, and Coarse grind — so you can match the processing method to your preferred brewing style and get the most out of every cup.
