My first scotch was 30 year old Ballantine. After that I was sold. My favorite now is cask strength A'bunadh:
It has so many flavors that hit you, but at $80.00 a bottle it's a bit steep.
I only like whiskeys I can drink neat, or with a few drops of water.
I've recently taken to Jack Daniels. It is better than similarly priced scotches.
