Not to be confused with the whiskey made at George Washington’s Mount Vernon estate starting in 1798, this Mount Vernon brand was started by Edwin A. Clabaugh and George U. Graff of Baltimore. They sold the brand to Henry S. Hannis of Philadelphia in 1873; it was later purchased by Cook and Bernheimer, a wholesaler from New York. There was also a “Mt. Vernon” rye competitor, causing confusion in the marketplace. It appears based on cursory label research that multiple distillers were contracted to produce the whiskey; this bottle was distilled by the Hannis Distilling Company of Pennsylvania. This bottle was likely filled around 1915; one can imagine that it was hoarded away before prohibition began in 1920, which kept it from being consumed and allowed it to survive over a decade intact. The foil enclosure with a twist-wire has proven to be an excellent seal over the century plus. Note there is no alcohol percentage listed on the bottle.
