This is a stupid point. There's no single authority on what is or isn't a "bourbon." According to federal law & regs, TN whiskey IS a bourbon. But the feds don't produce or distribute the hooch, so who really cares? Marketing depts and whiskey snobs might want to distinguish between bourbon & TN whiskey, but restaurants & bars are not going to make a separate category on their menus just for JD & GD. Lincoln County Process is just bourbon-plus or American whiskey-plus. Anyone who struts around correcting people about this is just being a poseur.
