Much of the whiskey produced in the US is from a major plant in Indiana. Smaller bottlers buy it then pretend it is a craft product.
My daughter in law, an architect, designed their tasting room (for their customers, the “artisan distillers”). I had to give her a crash course in the finer details of bourbon before she jumped on the MGB corporate jet and did the bourbon trail.
Here’s a YouTube video on the tasting center/sales center that my DIL put together for MGP at the distillery.
