The effort to make up this deficiency by longer contact of coffee and water, or repeated pouring through, results in no extraction of the oils
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly supported by the passage. The text explicitly states that 'The effort to make up this deficiency by longer contact of coffee and water, or repeated pouring through, results in no extraction of the oils,' which directly confirms that prolonged contact or repeated pouring does not extract aromatic oils.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (the passage presents scientific observations without naming a specific source). The stance is correctly marked as 'asserts' - the passage makes a definitive statement. The sentiment 'negative' is appropriate given the dismissive tone toward the ineffectiveness of prolonged contact. The time qualifiers are correctly null since the passage provides no temporal scope. Context is appropriately empty as no restrictive context is needed. The quote appears verbatim in the passage and directly supports the claim that prolonged contact or repeated pouring does not extract aromatic oils.
draws out undesirable elements, such as coffee-tannin, which is soluble in water at any temperature and is governed by the time of contact

- groundedness 1.00 pass — The claim is directly stated in the passage. The text explicitly says 'The effort to make up this deficiency by longer contact of coffee and water, or repeated pouring through, results in no extraction of the oils, but draws out undesirable elements, such as coffee-tannin.' This fully supports the claim that prolonged contact or repeated pouring draws out undesirable elements including coffee-tannin.
- qualifier_fidelity 0.95 pass — The claim is highly faithful to the passage. The quote appears verbatim and accurately captures the passage's assertion that prolonged contact/repeated pouring draws out undesirable elements like coffee-tannin. All qualifiers are correct: viewpoint is 'author' (the passage presents this as factual statement, not attributed to a named source), stance is 'asserts' (the passage states this as fact, not disputed), sentiment is 'negative' (undesirable elements is clearly pejorative), time is null (passage provides no temporal scope), and context is empty (appropriate, as the passage gives no contextual restriction). Minor deduction only for slight semantic precision: the passage discusses this as a result of attempting to compensate for weak extraction, though this does not materially affect the claim's fidelity.
