Duffy's Pure Malt Whiskey was a malted barley whiskey, distilled by the Rochester Distilling Co. and Duffy Malt Whiskey Co. of Rochester, New York (and briefly Baltimore, Maryland), which was promoted not as flavourful intoxicant, but as "medicine for all mankind," promising to act as a curative agent for any number of maladies, including consumption, catarrh, pneumonia, malaria, bronchitis, croup, diphtheria, cholera, dyspepsia, as well as stomach and heart problems.


An analysis by the North Dakota Agricultural College found that Duffy's Pure Malt Whiskey was 91 proof (45.8% alcohol), and described it as "nothing more than neutral spirits colored and flavored" with "syrup added to make it 'smooth' and give it flavor," further finding it was not aged in wood, and had a low fusel oil content.[1]
