Tasty new cocktail

The other night I wanted to make a whiskey cocktail but didn't feel like juicing any fruit. So I went for the fruitiest thing in my cabinet, Cointreau. I really expected this to be a starting point, but I've made it three times since and it is really pretty good:

Slade Sunset (named for the 'town' in the Red River Gorge, KY area)

1.5 floz bourbon (I used OGD BIB)
0.5 floz Cointreau
4 good shakes of Peychaud's bitters

Shake with ice and strain. It's orangy, with more than a hint of gentian. The color is delightful.

Enjoy!

Sounds like a variation on the Old Fashioned with more bitter and less or hardly any sweetness. I've never had Cointreau before but I understand it to be bitter/sweet and ogangie.

That sounds delicious. I love cointreau in mixed drinks. I'll pick up some bitters and try the "slade sunset."
