Yellowstone is an American brand of Kentucky Straight Bourbon Whiskey founded in 1872 and owned and marketed by MGP Ingredients.

[1][2] In 1920, the Yellowstone Bourbon brand was produced by James Thompson and Brothers and was bottled for "medicinal purposes only" during Prohibition.

[3] Thompson and Brothers was one of only six companies that were granted permits to bottle medicinal whiskey (from existing stocks – distilling was not allowed).

[5][full citation needed] The Thompson family maintained control of the company until 1991, at which time it was acquired by Guinness, which merged it with Schenley Industries and named the new entity United Distillers (now Diageo).

[9][10] In April 2021, MGP Ingredients completed its acquisition of Luxco, making them the owners of the Yellowstone brand.
