Difference between Whisky & Scotch ?
Whiskey(with an 'ey') is distilled grain alcohol; Whisky( -y) is the same, but made in Scotland, most often flavoured by smoking the grain in peat smoke. If you order a "whiskey" in a London pub, you'll likely get a shot of scotch whisky.

RYE: Canadian whiskey
BOURBON: American whiskey (must contain corn as primary grain)
