Copper-sulfur mechanism, approximately 75°C ethanol statement and equal-amount column evaporation/condensation description need specialist checking. Do not use the paper as a safety protocol or infer that discarding foreshots alone establishes methanol safety. Source cut-point examples are not bourbon operating instructions.
Still design, reflux, copper contact and fraction selection affect which congeners reach new-make spirit. Relative volatility varies with the liquid matrix; a neat-compound boiling-point list is insufficient.

Evidence
Still design, reflux, copper contact and fraction selection affect which congeners reach new-make spirit. Relative volatility varies with the liquid matrix; a neat-compound boiling-point list is insufficient.
Location and context
Sections 4.3–4.3.3 in the publisher review. This is a paraphrase, not a quotation or independent replication.
Annotation
