The Dewar's whisky brand was created by John Dewar, Sr. in 1846. Under the control of his two sons, John A. Dewar Jr. and Thomas "Tommy" Dewar, the brand expanded to become a global market leader by 1896. Tommy became famous as the author of a travel journal, Ramble Round the Globe, which documented his travels while publicizing the Dewar name. Dewar's eventually expanded their product by constructing the Aberfeldy Distillery in 1896.
The company joined Distillers Company in 1925. Distillers was acquired by Guinness in 1986, and Guinness merged with Grand Metropolitan to form Diageo in 1997. Diageo sold Dewar's to Bacardi the next year.
