Processing Methods: Washed, Honey, and Natural

From Cherry to Parchment

Once a ripe coffee cherry is picked, the clock starts ticking. The fruit must be processed within hours to prevent uncontrolled fermentation. The method chosen -- washed, honey, or natural -- determines a significant portion of what you taste in the final cup.

On our farms in Caicedonia, Valle del Cauca, we use all three methods, tailoring the process to each lot based on variety, ripeness, and the flavor profile we want to achieve. I have spent years experimenting with process variations, and the results have taught me that processing is where science and intuition meet.

Washed (Lavado)

The washed process is Colombia's traditional method and remains our highest-volume approach.

Steps:

1. Depulping -- mechanical removal of the cherry skin and most of the fruit flesh

2. Fermentation -- beans sit in fermentation tanks for 12-36 hours, where naturally occurring microorganisms break down the remaining mucilage

3. Washing -- beans are rinsed with clean water to remove all fermented mucilage

4. Drying -- clean parchment coffee is dried to 10-12% moisture

Cup profile: Washed coffees are known for clarity. You taste the bean itself -- its terroir, variety, and altitude -- without the fruit flavors that other methods introduce. Expect bright acidity, clean sweetness, and defined flavor notes.

For our Caturra lots, washed processing consistently brings out that citrus brightness that Colombian coffee is famous for. It is a process that rewards good farming because there is nowhere to hide -- if the cherry was not picked at peak ripeness, you will taste it.

Honey (Miel)

The honey process is a hybrid that leaves some or all of the mucilage on the bean during drying.

Variations:

• White honey -- ~10-20% mucilage left (lightest, closest to washed)
• Yellow honey -- ~25-50% mucilage
• Red honey -- ~50-75% mucilage
• Black honey -- ~80-100% mucilage (heaviest, closest to natural)

Cup profile: Honey-processed coffees offer a bridge between washed clarity and natural fruitiness. They tend to have rounder acidity, more body, and subtle stone-fruit or caramel sweetness. The more mucilage left on, the more fruit influence in the cup.

Key challenge: Drying must be carefully managed. The sticky mucilage attracts mold and insects, requiring constant turning and monitoring.

I have developed a particular fondness for black honey Bourbons. The caramel sweetness and body that come from leaving nearly all the mucilage intact, combined with Bourbon's natural sweetness -- it creates something special. But it demands constant attention on the drying beds. One day of neglect and you can lose the whole lot.

Natural (Seco)

In natural processing, the entire cherry is dried intact -- no depulping, no fermentation tanks.

Steps:

1. Sorting -- cherries are floated to remove defects and unripe fruit

2. Drying -- whole cherries are spread on raised beds or patios and dried for 15-30 days

3. Hulling -- once dry, the entire dried fruit is mechanically removed

Cup profile: Naturals are the boldest process. Extended contact between the seed and the fruit produces intense fruitiness -- think blueberry, strawberry, tropical fruit. Body is heavy, acidity is muted, and sweetness is pronounced. The best naturals are extraordinary; poorly executed ones taste fermented or dirty.

Choosing the Right Process

Process selection is not random. We consider:

• Variety -- some varieties (like Geisha) express exceptional complexity through natural or honey processing
• Weather -- naturals require extended dry periods; washed is safer in rainy conditions
• Market -- buyers increasingly request specific processes
• Risk tolerance -- naturals carry higher defect risk but command premium prices when executed well

We document fermentation type, duration, drying method, and temperature for every lot -- building a dataset that helps us replicate our best results. When a lot scores 87+ on the cupping table, I want to know exactly what we did so we can do it again.

For a deeper look at how fermentation science -- including our work with levaduras (yeasts) -- shapes these profiles, see our post on fermentation science.
