Updated March 2026.
Yellowstone Bourbon is a Luxco brand — Luxco is MGP Ingredients’ branded-spirits division — with Limestone Branch Distillery in Lebanon, Kentucky as the named home and Stephen Beam as master distiller. That is the company story. It does not mean every SKU is distilled at Limestone Branch. The 15 July 2026 Limited Edition press release is a 101-proof blend of 7- and 14-year Kentucky straight bourbons; those barrels were not described as Limestone distillate. Read the neck.
