CC North or South
An interesting question. I've known product to be similar but with different names for different markets do to alcohol content but CC Cdn 40%/vol should be CC Imp ? %/vol. If your Imported version states 40% than there should be no real difference as it is a blended whisky however I'm not aware of this happening. If its less % then the blend was changed for the market's taste. If the same %/vol then was it an error or something?
Check this out and let me know.
