I.W. Harper Gold Medal Kentucky Straight Bourbon 1980s / Japanese Import

The I.W. prefix in this brand name derives from Isaac Wolfe Bernheim, who founded the brand. With his brother he helped establish Louisville in Kentucky as a centre for Bourbon production. Sadly, he felt Harper was a more marketable name than his own to apply to the bottles. 

This was distilled and bottled at the Bernheim distillery in Louisville by the Schenley company.

Schenley were eventually bought over by United Distillers who discontinued the I.W. Harper brand in the 1980s, shortly after this was produced. The modern iteration of United Distillers, Diageo, revived the brand in 2015, although it is no longer made at Bernheim, which was sold to Heaven Hill in 1999.
