Gibson's Finest is a brand of Canadian Whisky produced between 40% & 46% alcohol by volume (80 & 92 U.S. proof).
[2] The Gibson's whisky brand was started by the Irish-born spirits merchant John Gibson at a distillery in Pennsylvania along the Monongahela River on 40 acres (16 ha) of land that he bought in 1856.
[1] He produced wheat, malt, and especially rye whiskey at the distillery.
Prohibition in the United States closed the distillery, and shortly afterwards the entire Gibson plant and its contents were auctioned off.
Today, Gibson's Finest Canadian Whisky brands are owned by family distiller, William Grant & Sons and produced at the Hiram Walker distillery in Windsor, Ontario.
