A vintage bottle of I.W. Harper Gold Medal Bourbon, produced at the Old Bernheim distillery in the late 1980s (the bottle code says 89). The I.W. Harper brand was introduced in the 1870s by the Bernheim Brothers. The ‘I.W.’ refers to the initials of Isaac Wolfe Bernheim, but a different surname was chosen for marketability. The brand was discontinued in the United States in the 1980s, when Schenley decided it would be more profitable to produce the bourbon solely for the Japanese market. After a 30 year absence, Diageo reintroduced the brand to the US market in 2015.
