I would say one should identify if they are looking for a high rye, low rye or wheated bourbon for mixing<br /><br />Hard to beat Old Grand Dad BIB or 114 for a high rye mixer or for sipping. WT 101 also works well for mixing<br /><br /> For a lower rye, many of the mid to low shelf Beam and Heaven Hill products will do well as a serviceable mixer at a good price. KC is a bit pricier as a mixer but should work very well with 100 pf to stand up well for mixing<br /><br />For a wheated OWA, Weller SR or Makers will do well for mixing<br /><br />I'm more of a neat sipper and don't do cocktails much so personally I would look for mid to lower shelf for mixing
