I don't have the educated taste buds or years of experience to pull from but I have tried several and if I was to pick one that was less nasty than the others I pick Makers Mark.
Just can't quite get the taste for it. Heck I used to love miller lite but now would rather have bud light so tastes do change!!!
Maybe I'll acquire the taste for bourbon one day??? Hmmm I kinda doubt it but never say never!!
