Hannush traces wider American use of master distiller as a prestige title to the1960s–1970s while also identifying earlier individual promotional uses. The title's duties and credential expectations vary; it should not be projected backward as a uniform nineteenth-century office.
Supported by one complete secondary-source reconstruction with verified locators. Underlying period advertisements and trade records remain uninspected.
Source-attributed chronology, not proof of a first-ever use. Lack of a universal title credential does not mean that professional qualifications, licensing or technical competencies do not exist.
The source separates scattered early marketing language from the later individualized job title and documents wide variation in present-day duties.
