A lot is not simply a quantity. In craft chocolate, a lot is a claim. It is an assertion that a specific set of beans, harvested from a specific section of a specific farm at a specific time, fermented under documented conditions, dried to a measured moisture level, and packed into numbered sacks, can be tracked from the moment the pod was cut until the moment the finished bar reaches the person eating it.
That chain of documentation is what traceability actually means. Not the word printed on packaging. Not the QR code that, when scanned, returns a generic origin story about farmers in a tropical country. The real thing: a continuous, verifiable record that connects the bar in someone's hand to the tree it came from.
At Blue Valley Chocolate, every batch begins as a lot. Here is how a lot is born.
It Starts at the Harvest Record
The first document in a lot's life is the harvest record: the date, the section of Finca Blue Valley where the pods were collected, the team members who harvested, the approximate number of pods opened, and the estimated fresh bean weight entering the fermentation box.
This information seems administrative. It is also agronomic. Tracking which farm sections are harvested on which dates, cross-referenced with weather data and the fermentation records that follow, is what builds the knowledge base that allows us to understand why a particular lot tastes the way it does. El Naranjo harvested in week three of the rainy season produces a different starting material than El Chaperno harvested in the dry-season transition, and the documentation of those variables is what makes the difference legible rather than mysterious.
The harvest record is not a spreadsheet entered after the fact. It travels with the lot from its first moment.
Box Assignment and Fermentation Documentation
When harvested beans enter a fermentation box, the box receives a lot identifier. That number will follow the beans through every subsequent step. The fermentation log attached to the lot records temperature readings twice daily, turn schedule and timing, aromatic observations at each monitoring visit, and the total duration before the beans are moved to drying.
The fermentation documentation is the most information-dense part of the lot record. A well-kept fermentation log tells the story of what happened inside the box in enough detail that a later batch showing a similar profile can be managed by reference to it. It also provides the evidentiary base for quality decisions: a batch that shows an unusual temperature curve, a delayed aromatic transition, or a cut test result inconsistent with the fermentation timeline is a batch that gets flagged, investigated, and potentially held rather than moved forward.
Craft chocolate producers who claim single-origin traceability but cannot produce a fermentation log for a given lot are making a marketing claim, not a supply chain claim. The fermentation documentation is where the real difference between genuine traceability and branded storytelling becomes legible.
Drying: Lot Identity Maintained
The move from fermentation box to drying beds could be a moment where lot identity is lost. Mixing different lots on the same drying bed is a common practice at scale, because managing multiple lots separately requires space, labor, and discipline that lower-margin operations deprioritize.
At Finca Blue Valley, lots maintain their identity on the drying beds. Each lot occupies a designated section, marked and kept separate. Moisture measurements are recorded per lot rather than per bed. The drying duration for each lot is logged individually, because the same bed under the same sun may dry at different rates depending on the bean density, the bean size, and the residual moisture arriving from fermentation.
The lot that arrives at the drying beds still carries its harvest date, its section of origin, and its fermentation record. By the time it is packed into sacks for transport to our factory in Brasilito, it has a documentation trail that covers every significant stage of its post-harvest life.
The Sack and What It Carries
Packed cacao beans leave Finca Blue Valley in labeled sacks. The label is not decorative. It carries the lot identifier that links the sack to the complete record package: harvest date and section, fermentation box number and duration, turn schedule, temperature log, cut test results, and final moisture reading.
At the factory, the lot record continues. Roast profiles applied to each lot are linked back to the lot identifier. Tasting notes from test batches inform the production decision. The final bar that results from a given lot carries, in principle, a complete lineage from tree to shelf.
This is what single-origin chocolate actually requires of its producers. The origin story is not a marketing narrative told in the past tense. It is a living document that begins at harvest and ends when the last bar from that lot has been sold and the records have been archived. Our full collection is the product of that chain. Come see where it starts on our farm tour.
We make three top chocolate bars right now: a 60% milk, a 70% dark, and a 78% dark with orange. All single-origin, all from our farm. Take a look.
