Supply Chain and Traceability

From Cherry to Container

When a roaster in Tokyo or Berlin opens a bag of specialty green coffee and reads the label -- farm, plot, variety, process, altitude, SCA score -- they are seeing the end result of a documentation chain that started months earlier in a Colombian coffee field. Traceability is what allows specialty coffee to command premiums over commodity. Without it, every bag is anonymous, and anonymity destroys value.

I learned this lesson early in our direct trade journey. A buyer in Dubai wanted to know the exact plot, the picker's conversion factor, the fermentation hours, and the drying method for a specific lot. We had the cupping score but not the full chain documented. That sale taught me: traceability is not paperwork -- it is the product itself.

The Lot Lifecycle

A single lot of coffee passes through multiple custody points, and at each one it must maintain its identity:

1. Cherry Collection (Farm)

• Harvested cherries are weighed by collector and plot
• Each day's collection from a specific plot becomes an initial wet lot
• The conversion factor (kg cherry per arroba of parchment) is recorded -- this measures cherry quality and picker selectivity
• Lower factor means better quality: a factor of 50 means excellent cherry; above 80 signals poor selectivity

I check conversion factors obsessively. When a picker's factor goes from 55 to 72 in a week, it tells me they are being less selective -- picking green and overripe cherries along with the ripe ones. That is not just a processing problem. It is a traceability problem, because poor cherry quality contaminates the lot's potential.

2. Wet Mill Processing

• Depulping, fermentation, washing, and initial drying happen at the farm's beneficiadero
• Each lot maintains its identity: plot code, variety, process method, fermentation hours, drying method
• The lot receives a wet mill code (e.g., SM-1294) that travels with it permanently

3. Parchment Storage (Bodega)

• Dried parchment coffee (pergamino) rests in the bodega at 10-12% humidity
• Lots remain separated by origin, process, and quality tier
• Inventory is tracked by weight, moisture, and storage duration

4. Dry Mill (Trilla)

• Parchment is hulled to produce green coffee
• Screen grading separates by size; density tables remove defects
• Each green lot receives a dry mill code linking back to the original wet lot
• Physical grading and cupping evaluation determine the quality tier
• Weight loss during hulling is typically 18-20% (parchment weight)

5. Export Preparation

• Approved lots are bagged in GrainPro-lined jute bags (69 kg standard)
• Each bag is labeled with lot code, origin, weight, and quality grade
• A standard 20-foot container holds approximately 250 bags

6. Export Documentation

• ICO certificate -- required for international coffee trade, issued by the exporting country
• Phytosanitary certificate -- from ICA (Colombia's agricultural authority), certifying pest-free status
• Certificate of origin -- proves Colombian origin for tariff and regulatory purposes
• Bill of lading -- shipping document that transfers ownership
• Quality certificate -- cupping scores, physical grading, moisture readings

Why Lot Separation Matters

The economics are compelling. A farm that mixes all its coffee into one large lot sells at the average quality level -- losing the premium that its best plots could command. A farm that separates by plot, variety, and process can:

• Price each lot independently based on its cup score
• Provide full traceability that buyers increasingly demand
• Identify which plots, varieties, and processes produce the best results -- feeding back into farm management decisions
• Build reputation as a traceable, transparent origin

On our farms, we maintain full traceability from cherry collection through export. Every lot can be traced back to the specific plot, harvest date, process method, and fermentation protocol that produced it. When I send a buyer a Bourbon lot from a specific high-altitude block processed with 72-hour anaerobic fermentation using levadura inoculation, that is not marketing. That is documented fact, with records at every custody point.

The investment in lot separation pays for itself. Our best plots -- certain Bourbon and Geisha blocks above 1,600 meters -- produce lots that score 86-89. If we mixed those with the Castillo from our lower blocks, everything would average out to 83-84. Lot separation captures the premium on the exceptional lots while still selling the solid lots at fair prices.

Container Logistics

The final step is physical: moving coffee from the dry mill to the destination port. This involves:

• Inland transport -- truck from dry mill to the port of Buenaventura (Pacific) or Cartagena (Atlantic)
• Fumigation -- required by some destination countries
• Container loading -- supervised to ensure bag count, weight, and lot identity are correct
• Ocean transit -- 3-6 weeks depending on destination, during which temperature and humidity can affect quality
• Customs clearance -- at both origin and destination, with full documentation required at each step

Every break in the documentation chain is a potential point of failure. Traceability is not just marketing -- it is operational discipline. When something goes wrong -- a lot arrives with high moisture, a cupping score does not match the pre-shipment sample -- traceability is what lets you trace the problem back to its source and fix it.
