Broad copper-contact role retained. PDF125 caption's universal conversion to copper sulfate is not a reliable mechanism; placement, compounds and operating conditions matter.
The passage follows discussion of still operation and spirit character.
Hyde identifies copper contact in the vapor path as a way to react with and reduce undesirable sulfur compounds, making material choice and placement part of still design.
