To me, the bourbon terms sometimes seems odd. Bottled in bond means a vintage whiskey and straight means the whiskey is minimum 4 years old :-)

The Old Grand Dad is today a Beam brand, and uses a special high rye mash bill different from the other Beam whiskies. The whisky is named after Basil Hayden, the original distiller Raymond Haydens grand-dad. The name is also known from Beam's Basil Hayden's bouron which also uses the same mash bill.
Nose : Shoe polish, rye, liqeur
Palate : Wow, pure rye heaven. It's very smooth and hasn't got a lot of wood. Is this OBE ? (old bottle effect). I do find slight similarities to this and AH Hirsch 16, and the AH Hirsch 16 did spend around 1½ decade in stainless steel tanks. One thing is sure, I am glad I have been stocking up on bourbons bottled last century. I get more from this. Mint, licorise, floor varnish, rye, vanilla, but this is also one of the least woody and smoothest bourbons I have tried
Finish : medium-long
Thanks to Mike Ly for the sample
