Im a big fan of bourbon. My goto when drinking straight is Willet Pot Still, but its getting to be tough to find.
Lately have gotten into the "craft cocktail" craze. Love almost any bourbon or rye cocktail.
For cocktails I like Buffalo Trace bourbon and Rittenhouse Rye. Have made some really good Old Fashioneds, Manhattans, Sazaracs and Whiskey Sours.
