As The Seasons Grey

1 oz Rye, Rittenhouse
1 oz Bourbon, Old Grand Dad 100
14 oz Coffee liqueur, St. George (NOLA)
14 oz Maple syrup (Grade A Dark Color, Robust Taste)
2 ds Bitters, Fee Brothers Black Walnut
1 ds Bitters, Angostura
1 ds Bitters, Angostura orange
1   Orange peel (as garnish)
Instructions
Stir, strain into old fashioned glass with a large cube or sphere. Garnish with an orange swath. If you're feeling ambitious, you can also smoke the drink with maplewood.
Notes
The St. George NOLA Coffee Liqueur is drier than most large producer coffee liqueurs, so adjust ratios or add another dash of Angostura bitters if using something sweeter. I prefer using "Grade A Dark Color, Robust Taste" syrup (formerly Grade B) in cocktails due to its stronger, more intense maple flavor.
