Alright, this one's a bit mysterious. According to the Preiss website, this is a Kentucky Straight Corn Whiskey, which means it was distilled (presumably in Kentucky) from a mash containing greater than 80% corn. Then why does it say Illinois Whiskey on the label? Well, it seems that the whiskey was matured in used oak barrels (bourbon can legally only be matured in new oak barrels) and these barrels were stored in Illinois. It also appears to have been bottled for Preiss by the McCormick Distilling Company in Weston, Missouri, who is the owner of the fictitious business name "Hirsch Distillers" according to the Missouri Secretary of State. The distillery that produced the whiskey is unknown.
