Bourbon is a minimum of 51 percent corn by law. Scotch and Irish styles use barley as their base. Canadian whisky is often mostly corn, but you can find some brands with a stronger rye base.
Scotch and Irish whiskies are made in beautiful copper stills often called pot stills. American whiskey is usually made in more modern stills -- known as column stills -- containing copper plates inside. This type of still is sometimes called a Coffey still, after Aeneas Coffey who patented his super efficient invention in 1831.
