Ross & Squibb Distillery (MGP)

One of the most influential distilleries in American whiskey that most consumers have never heard of. George Ross founded Rossville Distillery on the banks of Tanner's Creek in 1847; the Squibb Distillery was founded nearby in 1869. The modern facility was acquired by MGP Ingredients in 2011 and rebranded as Ross & Squibb in 2021. It has supplied bulk aged rye and bourbon to hundreds of brands — including many that market themselves without disclosing their production source. Produces approximately 75% of the commercial rye whiskey in the US. Also produces its own George Remus bourbon brand.
