Three commercial Scotch whiskies were examined with five fiber coatings after substantial preparation, including dilution to 13% alcohol and salt addition. CAR/PDMS performed well under the selected conditions, while other coatings favored different analyte classes. The study demonstrates that a measured volatile profile depends on extraction conditions as well as the beverage.

Findings And Method
Three commercial Scotch whiskies were examined with five fiber coatings after substantial preparation, including dilution to 13% alcohol and salt addition. CAR/PDMS performed well under the selected conditions, while other coatings favored different analyte classes. The study demonstrates that a measured volatile profile depends on extraction conditions as well as the beverage.
Evidence Boundaries
The sampled headspace is not an ordinary drinking glass. Peak-area response is not calibrated concentration or perceived intensity. Some internal-standard quantities and table labels are inconsistent; do not bulk-import numerical values without checking the original table and calibration. The related 2006 conference report substantially overlaps these samples and methods and should not be counted as independent replication.
Blending Lab Application — Researcher Synthesis
Teach partitioning and method selectivity as established principles. Require extraction technique, coating, dilution, temperature, time, salt, calibration and identification confidence beside future imported chemical data. Do not turn the most sensitive coating into a universal best-method claim.
The practical recommendation is distinct from the authors' tested result. Established chemistry and measurement definitions can be taught directly; a particular whiskey's response, a consumer segment or a profitable offer still requires appropriate evidence.
