Five bottles of Duffy's Malt Whiskey were recovered from an early twentieth-century deposit in Old Sacramento. Duffy's Malt Whiskey was first manufactured by the Walter B. Duffy Distilling Co., in Rochester, New York, in 1884. This bottle is made from amber glass, is nearly neckless and embossed with "THE DUFFY MALT WHISKEY COMPANY/ROCHESTER N.Y."
