This is my absolute go-to whiskey cocktail.  If you’re a fan of the classic Negroni (traditionally made with Gin), then the Boulevardier will be right up your alley.  In my opinion, this cocktail’s flavor profile goes a step further than a Negroni due to the use of [rye or bourbon] whiskey instead of Gin.  I personally prefer a nice, spicy, barrel-proof bourbon – it really brings out the depth of flavors in the cocktail.  Its a great balance of strong, sweet and bitter – the perfect pre/during/after-dinner cocktail.  Its the kind of cocktail that is not only delicious, but will garner a nod of approval from your bartender.  Cheers!
