Cobans are larger
judge verdicts (2)
- groundedness 0.70 pass — The passage directly states 'The Antiguas are medium, flinty beans; while Cobans are larger,' which supports the claim that Coban coffee beans are larger. The statement is clearly made by the author regarding the physical characteristics of these beans.
- qualifier_fidelity 0.90 pass — The claim is largely faithful to the passage. Viewpoint, stance, sentiment, time, and context all correctly reflect the source material. However, there is a minor issue: the quote 'Cobans are larger' appears in the context of comparing Cobans to Antiguas ('The Antiguas are medium, flinty beans; while Cobans are larger'), so the comparison is relative to Antigua beans specifically, not a general statement about Coban size. The context qualifier 'mountainous districts' is accurate but incomplete—the passage specifies both Coban AND Antigua are grown in mountainous districts, and the size comparison applies specifically to Cobans versus Antiguas, not just to Cobans in general. This is a very minor contextual precision issue that does not substantially undermine the claim's fidelity.
- Coban coffee makes one of most serviceable coffees on American market ⟨when properly roasted and blended⟩
Cobans make one of the most serviceable coffees on the American market
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The exact quote 'Properly roasted to a light cinnamon color, and blended with a high-grade combination, Cobans make one of the most serviceable coffees on the American market' appears in the text, and the claim accurately captures this assertion with appropriate context about roasting and blending.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (the passage is written in an authorial voice describing coffee grades). The stance is appropriately 'asserts' as the passage makes a direct declarative statement. The sentiment is positive, matching the connotation of 'serviceable' and the overall favorable description. The time qualifiers are correctly null since the passage provides no temporal specification. The context accurately reflects the passage's qualifier 'Properly roasted to a light cinnamon color, and blended with a high-grade combination.' The quote appears verbatim in the passage and directly supports the claim.
Waxy, bluish bean
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. Under Guatemala's Coban district, the passage explicitly describes the coffee as having a "Waxy, bluish bean" with additional characteristics. This is fully supported without any rewording or outside knowledge required.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The claim correctly attributes the statement to the author (not a named source), uses 'asserts' as the stance (the passage presents this as factual description), maintains neutral sentiment, has no time qualifiers (the passage provides none), and appropriately leaves context empty. The quote 'Waxy, bluish bean' appears verbatim in the passage under the Coban entry and accurately supports the claim about Coban coffee's characteristics.
handsome uniform roast with white center.
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The table explicitly describes Coban coffee as having a 'Waxy, bluish bean; handsome uniform roast with white center. Heavy body, fine acidity,' which fully supports the subject-predicate-object relationship presented in the claim.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (the passage presents this as factual description without naming a specific source). The stance is correctly marked as 'asserts' - the passage makes a declarative statement. The sentiment is positive, matching the connotation of 'handsome' and descriptive language. Time qualifiers are all null, which is correct as the passage provides no temporal information. Context is empty, which is appropriate as the passage does not restrict the claim to a specific sense or role. The quote appears verbatim in the passage under the Coban entry in the Trade Values column and directly supports the claim about Coban coffee's roast characteristics.
fine acidity.
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. Under the Coban entry for Guatemala, the Trade Values column explicitly states: 'Waxy, bluish bean; handsome uniform roast with white center. Heavy body, fine acidity.' The claim accurately reflects this passage text.
- qualifier_fidelity 0.85 pass — The claim is largely faithful to the passage. The subject (Coban coffee), predicate (has), object (fine acidity), viewpoint (author), stance (asserts), sentiment (positive), and time (null) are all accurate. The quote 'fine acidity' appears verbatim in the passage describing Coban coffee. However, the context qualifier is empty when it should specify that this refers to Coban as a district/origin producing coffee with specific characteristics (waxy, bluish bean with handsome uniform roast, heavy body, fine acidity). The passage uses 'Coban, t & m n' to identify it as a market/district name, and the fine acidity descriptor applies specifically to coffees from this geographic region. A more complete context would note 'Coban district coffee' or 'coffee from Coban region' to maintain fidelity to how the passage presents this information.
It is frequently compared with the fancy Cobans of Guatemala
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The exact quote 'It is frequently compared with the fancy Cobans of Guatemala' explicitly supports the assertion that Blue Mountain coffee is frequently compared with Coban coffee, with only the minor rewording of 'fancy Cobans of Guatemala' to 'Coban coffee.'
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly identified as 'author' (the passage itself makes this comparison, not attributing it to a named source). The stance 'asserts' is appropriate for the factual statement. The sentiment 'neutral' matches the objective tone of the comparison. The time qualifiers are appropriately null since the passage provides no temporal specification. The context is empty, which is correct as the passage does not restrict the comparison to a specific sense or role. The quote 'It is frequently compared with the fancy Cobans of Guatemala' appears verbatim in the passage and directly supports the claim.
