Is this coffee from one place, or is it a blend?
ALS-COFFEE-1.1-SOURCE-001
This question is asked as a test and produces a result for a real page.
Assertion
single_origin_claim_stated is_stated true
Applicability
- applies when
- the product is roasted coffee offered to consumers in any format
- signal
- product_type or title indicates coffee
Accepted evidence
- product_description — an explicit single-origin claim with a named place at region level or finer e.g. Single origin from one farm in Huila, Colombia.
- structured_data — the same statement inside the JSON-LD product description
- product_title — the claim in the product title where the title also names the place
Explicitly insufficient evidence
What does not count, and why. Published because the omission is where a check quietly becomes a claim.
- "single origin: Ethiopia" or any country-only claim
A country with dozens of non-comparable growing zones is true and uninformative; the minimum non-misleading content is a place specific enough that a buyer could ask about it. - "100% Colombian"
A national blend of thousands of farms satisfies this exactly; it is a purity claim about a country, not a claim about granularity. - a single-origin claim on a page that names two or more regions
The label and the content contradict each other, and a keyword check passes it because the phrase is present. - "direct trade", "relationship coffee", "farm direct"
These are sourcing-relationship claims routinely substituted for granularity claims, and they say nothing about how many places the coffee came from. - "single farm" where the named entity is a washing station
A station buying cherry from hundreds of smallholders is one site rather than one farm, so the words overstate the granularity by an order of magnitude. - "our single origin range" or a collection-level statement
A statement about the seller's catalogue is not a statement about this product, and the engine cannot tell the two apart.
Conflict rules
- When the title says single origin and the description names a blend of countries — then record the contradiction; the standard reports that the page disagrees with itself rather than choosing a side precedence: product_description > product_title
- When the seller publishes its own definition of single origin elsewhere on the site — then a site-level definition does not change what this page states; evidence is read from product surfaces only
What a pass licenses
A pass establishes: That readable product text on this page contains a single-origin phrase, quoted verbatim where a clean sentence exists.
A pass does NOT establish: The granularity of the origin, that a place is named at all, that the claim is not contradicted elsewhere on the page, or that the sentence is about this product rather than the seller's range.
Discrimination
Measured fail rate: 89.0% (n=100 products asked)
Predicted before this standard had ever run: 40-75% — the real rate is higher, so the entry discriminates less than predicted.
Blends are at least as common as single-origin lots in retail coffee, and blends will correctly fail, but the engine's dictionary also matches "single estate" and "single farm" and will pass any sentence containing them regardless of subject. The band is wide because the pass condition is looser than the question.
Known gaps
- "Most cheap versions are made from thin stamped steel." — false_pass
The comparative veto in subject.ts tolerates exactly one word between "most" and its verb, so two-word noun phrases walk through. The coffee analogue credits a contrast against the seller's own other products. - "Love that it's fragrance-free!" — a customer in Portland. — false_pass
Review quotes credited as the store's statement.
For a shopper
Single origin has no agreed definition, so it can mean one farm or one country, and those are very different purchases. The useful check is whether a place is named at region level or finer, because a country name alone tells you almost nothing about what is in the bag.
For a merchant
State the granularity and the named entity at that level — region and municipality for a regional lot, the farm or estate name for a single-farm lot, or the co-operative and the number of contributing producers for an aggregated lot — rather than the phrase alone.
Grounding
- Coffee & Conservation, independent coffee certification and sourcing reference (consumer_guide)
that long-running independent consumer reference material exists to explain what coffee sourcing and certification labels do and do not mean, which is written because shoppers cannot read the labels unaided - ISO 3509 coffee and coffee products vocabulary, as summarised in trade reference material (trade_body)
that the international coffee vocabulary defines processing classes but contains no definition of single origin, single estate or microlot, so those terms resolve against no external definition
