It is funny you say that Ivan. I found Bushmills to be close to some Sherry cask malts. A bit like Macallan, Balvenie double wood or Glenfarclas.
Bushmills is a drink I would certainly say would be good to try for someone looking at getting into whisk(e)y.
Cougar, you are right, the Scotch market needs a good supply of ex bourbon barrels. For a Scotch whisky to obtain that colour it would probably spend 20 years in a Sherry cask. Seen pictures of I think 30 year old Dalmore that looks like blood.
