Use Guglielmi for product development and launch positioning; use Wisniewski as independent corroboration of the 1984 launch and later prominence of the format.
Blanton’s launched in the United States in 1984 as a deliberately conceived premium single-barrel bourbon. Its product architecture combined selected individual barrels with named warehouse provenance, distinctive packaging, high shelf pricing, and promotion aimed at affluent buyers.
Verified against the cited, locator-checked passages in Guglielmi and Wisniewski. Publication wording must retain the stated boundary around first-ever and sole-cause claims.
The 1984 U.S. launch and the deliberately premium single-barrel positioning are well supported. Do not describe Blanton’s as the first single-barrel whiskey ever made, claim that it alone created the premium-bourbon market, or publish the Japan-market chronology without attributing that correction to Guglielmi unless additional independent launch records are added.
Three verified excerpts and three ready citations support the year, single-barrel format, deliberate premium brief, barrel-selection mechanism, and market positioning. The claim is intentionally narrower than the existing market-wide causal claim.
Editorial use
Use this claim as a dated premiumization milestone and a case study in product architecture: barrel selection, provenance storytelling, packaging, pricing, and audience were coordinated into one premium offering.
Boundary
This record does not establish that Blanton’s was the first single-barrel whiskey ever made or the sole cause of premium bourbon’s rise. Attribute the U.S.-before-Japan correction to Guglielmi unless independent launch documentation is added.
