Jack Daniels is all about the name, it's overpriced! Have you tried Jim Beam, as used by Corabar Steve? Much nicer! Even Asda own label bourbon is as good as JD..
My faves are Tennents, Stella, and Whisky & Irn Bru (any whisky really, I'm a bit more picky if I'm drinking it straight). Can't stand cider or Guinness!
