From Coffee Cherry to a Stable, Storable Material

Coffee’s journey begins with a material that contains substantial moisture and changes quickly: freshly harvested cherries. After picking, the fruit has to enter a post-harvest process suited to the method chosen. In wet processing, the fruit flesh is removed and the beans pass through fermentation, washing and drying. In dry processing, the whole cherries are dried before the outer layers are removed. The details differ, but the common objective is to move coffee from a fresh, unstable state into a more stable condition for storage. Drying is particularly important because moisture directly affects storability. It is also a stage where control of time, drying surface, environmental conditions and turning can influence quality. Once initial processing is complete, the product is not yet roasted coffee. Depending on where it sits in the chain, it is typically parchment coffee or green coffee.

From Processed Coffee to Green Coffee

Processed coffee still contains material layers that have to be removed before it becomes commercial green coffee. Dry milling removes parchment or other surrounding layers, after which the coffee is cleaned and graded against criteria suited to the market. This is the stage at which a post-harvest agricultural product becomes a more standardized raw material that can be traded, stored and transported. Research in Kenya describes this chain through two processing levels: initial processing at a wet mill and dry milling to produce green coffee. The study also notes that grading and quality control form part of the value-creating work that takes place before coffee moves deeper into trade. This is why the “green bean” on the market is not simply a coffee cherry with its skin removed; it is the result of a process that prepares a lot for storage and commerce.

From the Producing Region to the Consuming Market

Once green coffee exists as a tradable lot, it may pass through a cooperative, trader, exporter or integrated business. Coffee can be aggregated, bagged, stored and moved to a port or other handover point before export procedures are completed. In the importing country, an importer or intermediary receives the shipment, checks it and arranges delivery to a roaster or the next customer. Not every handover means that ownership changes. A logistics provider may only transport the coffee; a warehouse may only store it; an inspection body may only provide test results. That is why any description of the “links” in the chain should distinguish physical activities from ownership and commercial responsibility. The SCA Systems Map likewise emphasizes that one actor can participate in several activities, while supporting services may sit outside the direct transformation of the bean.

From Green Coffee to Roasted Product

The roaster receives green coffee, evaluates the lot and chooses a roasting approach suited to the intended product. Roasting uses heat to transform the bean’s composition and sensory characteristics. The beans are then cooled and, depending on the product, kept whole or ground. Finally, the coffee is packaged in a format suited to the sales channel. At this point, it is useful to distinguish transformation from movement. Roasting, grinding and packaging change the product’s state or usability. Warehousing, transport and delivery mainly preserve that state while moving the product elsewhere. De'Longhi describes stages including purchasing, transport, roasting, grinding, packaging and sale; the sequence is useful for orientation, but it should not be mistaken for a structure that every business follows.

From Roasted Product to the Beverage

At the end of the journey, roasted coffee may be sold through a shop, coffee house, restaurant, online channel or directly for home use. If the buyer brews it, another transformation takes place: water interacts with coffee through a particular method to produce a beverage. At that point, the product’s value is no longer determined by the coffee package alone. It also depends on equipment, technique, time and service. A coffee shop makes this especially visible. The same beans can become very different drinks depending on the brewing method and recipe. Reaching the “drinker” therefore does not always mean reaching someone who bought a retail bag of coffee. The two routes may meet at retail, then separate again into home consumption and beverage service.

Not Every Coffee Lot Follows the Same Route

Some lots pass through several intermediaries. Others are aggregated by a cooperative and sold to an exporter; some businesses buy directly from farmers; and integrated chains may place several stages under one company. FAO notes that coffee is often exported relatively early in the chain, meaning that much value-added processing continues in consuming markets. That is a system-level observation, not a rule that applies to every individual lot. The route varies with scale, country, coffee type, buyer requirements and business model. For that reason, when tracing a particular lot, the most useful question is not “How many steps are in the standard chain?” It is where the lot was processed, who was responsible at each point, and how the coffee changed in form and condition along the way.
