Malt whiskey is whiskey that is made from a fermented mash produced primarily from a malted grain. Unless otherwise indicated, it is generally assumed that the primary grain is barley, although whiskey is also made using malted rye or other grains.
Malted whiskey was the specialty of the Walter B. Duffy Co. and it was marketed across the United States as a heart tonic, remedy for pneumonia, consumption and haemorrhages.
Ultimately, “The Great American Fraud” helped lead to the passage of the Pure Food and Drug Act in 1906. This movement, along with the temperance movement and growing sophistication in medical knowledge, spelled eventual doom for Duffy’s.
Beginning in 1915, Duffy's Pure Malt Liquor ceased to make medicinal claims other than its being a "tonic stimulant" and "household remedy." As Prohibition set in, Duffy's dropped the label "whiskey" and marketed its product strictly as a "tonic."
