Heading to the Southern USA in pursuit of distilleries to visit, it's easy to get confused. And that's before you've even had a drink. American bourbon and whiskey are different. Bourbon doesn't have to be made in Bourbon County, or even in Kentucky. You can make bourbon in Tennessee, or even in Texas if you abide by the rules. Tennessee is more noted for its whiskey, though. And in the USA they do spell it whiskey except for the people who spell it whisky.
